Web applications become an important part of our daily lives. Many other activities are relay on the functionality and security of these applications. Web application injection attacks, such as SQL injection (SQLIA), Cross-Site Scripting (XSS) and Cross-Site Request Forgery (XSRF) are major threats to the
security of the Web Applications. Most of the methods are focused on detection and prevention from these
web application vulnerabilities at Run Time, which need manual monitoring efforts. Main goal of our work
is different in the way it aims to create new systems that are safe against injection attacks to begin with, thus allowing developers the freedom to write and execute code without having to worry about these attacks. In this paper we present SQL Attack Scanner (SQLAS) a Tool which can detect & prevent SQL injection Attack in web applications. We analyzed the performance of our proposed tool SQLAS with various PHP web applications and its results clearly determines the effectiveness of detection and prevention of our proposed tool. SQLAS scans web applications offline, it reduces time and manual effort due to less overhead of runtime monitoring because it only focus on fragments that are vulnerable for attacks. We use XAMPP for client server environment and developed a TESTBED on JAVA for evaluation of our proposed tool SQLAS.
Prevention of SQL Injection Attacks having XML DatabaseIOSR Journals
This document discusses an XML-based technique called XML-SQL for preventing SQL injection attacks. It proposes submitting all client data to the server in an XML format and having the server validate the entire XML file against pre-defined validation rules at once, rather than validating each data item separately. This allows complex data to be validated more easily and generically. The technique aims to separate the data validation from the application development to make the developer's job simpler and more secure.
SQL injection is the major susceptible attack in today’s era of web application which attacks the database to gain unauthorized and illicit access. It works as an intermediate between web application and database. Most of the time, well-known people fire the SQL injection, who is previously working in the organisation on the present database. Today organisation has major concern is to stop SQL injection because it is the major vulnerable attack in the database. SQLI attacks target databases that are reachable through web front. SQLI prevention technique efficiently blocked all of the attacks without generating any false positive. In this paper we present different techniques and tools which can prevent various attacks.
The document discusses various types of injection attacks, including SQL injection, cross-site scripting (XSS), and OS command injection. It describes the mechanisms of these attacks and how they can be used to steal data, bypass authentication, and compromise systems. The document then provides several countermeasures that can be implemented to help prevent injection attacks, such as input validation, prepared statements, firewalls, access control, and encryption.

Routine Detection Of Web Application Defence FlawsIJTET Journal
Abstract— The detection process for security vulnerabilities in ASP.NET websites / web applications is a complex one, most of the code is written by somebody else and there is no documentation to determine the purpose of source code. The characteristic of source code defects generates major web application vulnerabilities. The typical software faults that are behind of web application vulnerabilities, taking into different programming languages. To analyze their ability to prevent security vulnerabilities ASP.NET which is part of .NET framework that separate the HTML code from the programming code in two files, aspx file and another for the programming code. It depends on the compiled language (Visual Basic VB, C sharp C#, Java Script). Visual Basic and C# are the most common languages using with ASP.NET files, and these two compiled languages are in the construction of our proposed algorithm in addition to aspx files. The hacker can inject his malicious as a input or script that can destroy the database or steal website files. By using scanning tool the fault detection process can be done. The scanning process inspects three types of files (aspx, VB and C#). then the software faults are identified. By using fault recovery process the prepared replacement statement technique is used to detect the vulnerabilities and recover it with high efficiency and it provides suggestion then the report is generated then it will help to improve the overall security of the system.
PHP is one of the most commonly used languages to develop web sites because of i
ts simplicity, easy to
learn and it can be easily embedded with any of the databases. A web developer with his basic knowledge
developing an application without practising secure guidelines, improper validation of user inputs leads to

application causes work flow deviation attacks.
In this paper, we are analyzing the complete behaviour of a
web application through static and dynamic analysis methodologies
Base Paper Abstract:
Most web applications have critical bugs (faults) affecting their security, which makes them vulnerable to attacks by hackers and organized crime. To prevent these security problems from occurring it is of utmost importance to understand the typical software faults. This paper contributes to this body of knowledge by presenting a field study on two of the most widely spread and critical web application vulnerabilities: SQL Injection and XSS. It analyzes the source code of security patches of widely used web applications written in weak and strong typed languages. Results show that only a small subset of software fault types, affecting a restricted collection of statements, is related to security. To understand how these vulnerabilities are really exploited by hackers, this paper also presents an analysis of the source code of the scripts used to attack them. The outcomes of this study can be used to train software developers and code inspectors in the detection of such faults and are also the foundation for the research of realistic
vulnerability and attack injectors that can be used to assess security mechanisms, such as intrusion detection systems, vulnerability scanners, and static code analyzers.

A Review paper on Securing PHP based websites From Web Application Vulnerabil...Editor IJMTER
In today’s Era, Web applications are one of the most part ubiquitous platforms for
information sharing and services over Internet which play significant role in individual life as well
as in any country’s growth. Web applications have gone through a very rapid Growth As they are
increasingly used for the financial organization, government, hospitality and many critical services.
Web applications become a popular and precious target for security attacks. at the present time,
billions of transactions are done online through net banking, online shopping, online billing and
many more. Even though these applications are used by lots of people modern web applications
often implements the complex structure requires for user to carry out actions in given order, in
many cases the security level is too low, which makes them vulnerable to get compromised. Even
though a large number of techniques have been developed to build up web applications and
mitigate the attacks toward web applications, there is little effort constant to drawing relations
among these techniques and building a big picture of web application security(WAS) research. In
this paper, we present a survey on various types of web application vulnerabilities(WAV).
This document summarizes research conducted on exploiting vulnerabilities in Apache web servers through command line arguments. The researchers created a test environment with one machine hosting a local Apache server and another for browsing. They were able to use command line injections in a PHP search query to gain administrative access and traverse the file structure. The document reviews related literature on topics like directory traversal, SQL injections, and input sanitization. It provides an overview of the computing environment used, which included setting up an Apache server on one virtual machine for testing exploits.
The International Journal of Engineering and Science (The IJES)theijes
This document summarizes a research paper that proposes a new intrusion detection system (IDS) to identify distributed denial-of-service (DDoS) attacks in multitier web applications. The system models relationships between web server requests and database queries to detect attacks where normal traffic is used maliciously. It handles both deterministic and non-deterministic relationships. For static websites, the system classifies traffic into patterns and builds a mapping model. For dynamic websites, it aims to extract one-to-many mappings despite parameter variations and overlapping operations. The paper also discusses SQL tautology attacks, which exploit input fields to bypass authentication or extract all data.
This document summarizes vulnerabilities in web applications and methods to protect against them. It discusses how vulnerabilities can occur from issues like format string exploits, SQL injection, and cross-site scripting. The document also describes different approaches to testing for vulnerabilities, including white-box and black-box testing. Additionally, it analyzes vulnerability information from various organization's lists of top vulnerability categories to provide a comparative overview. The goal is to help organizations identify and address vulnerabilities in their web applications.
Prevention of SQL injection in E- Commerceijceronline
Structured Query Language (SQL) injection, in present scenario, emerges as one of the most challenging fact to effect on the online business, as it can expose all of the business transaction related sensitive information which is stored in online database, inclusive of most highly secured sensitive information such as credit card passwords , usernames, login ids, credentials, phone, email id etc. Structured Query Language injection remain a responsibility that when intruder gets the ability with SQL related queries which is passed to a back-end database. The query which is passed by the intruder to the data, can allow the query to data which is an assisting element with database and required operating system. Every SQL Query that allows the inputs from the attacker sides can defect our real web application. Intruder which attempts to insert defective SQL query into an entry field to extract the query so that they can dump the database or alter the database which is known as "code injection technique" and this type of attacker is also called attack vector for websites and usually used by any type of SQL database. Through this research paper, our endeavour is to understand the methodology of SQL injection and also to propose solution to prevent SQL Injection in one of the most vulnerable field of E commerce.
Attacks on web services need to secure xml on webcseij
Web Services are the newest mechanism of communication among applications. Web Services are independent of both hardware and software infrastructure, they are very flexible and scalable. Lack of security features provided by the web services creates a window of opportunity for attackers. Web Services are offered on Http with Simple Object Access Protocol (SOAP) as an underlying infrastructure. Both SOAP and Web Services relies heavily on XML, hence, Web Services are most vulnerable to attacks using XML as an attack parameter. Several attacks use XML and most of them lies in the category of XML injection.XML based attacks discussed in this study covered a variety of attacks for example Denial of Services and Data Theft, escalation of privileges etc. Among these attacks the injections attacks on the web services are more severe and being given special attention. This study is aimed at providing an insight of the various forms of XML injections such as XPath injection, Coercive Parsing, and oversize payload.
IRJET- An Efficient Technique for Finding SQL Injection using Reverse Proxy S...IRJET Journal
This document discusses an efficient technique for detecting SQL injection attacks using a reverse proxy server. It proposes redirecting user inputs to a proxy server before sending them to the application server. A data cleansing algorithm would then sanitize the inputs by checking for malicious patterns. If patterns are found, the request is rejected, otherwise it is passed to the application server. The technique aims to detect and prevent 93% of SQL injections and 85% of cross-site scripting attacks with low false positives. It uses techniques like pattern matching, sanitization of HTML/JavaScript, and tokenization to cleanse inputs before execution on the database.
A Study on Detection and Prevention of SQL Injection AttackIRJET Journal
This document discusses SQL injection attacks and proposes a method for detecting and preventing them. It begins with an introduction to SQL injection attacks and discusses how they work. It then reviews related literature on detecting and preventing SQL injection. The proposed system would use Aho-Corasick string matching to build a state machine model of valid SQL queries during static analysis. Runtime monitoring would then check dynamically generated queries against this static model to detect malicious queries before database execution.
Modeling and Testing Security and Privacy Requirements: A Use Case-Driven App...Lionel Briand
The document discusses an approach for capturing security requirements in a structured manner using use case modeling techniques. The approach, called Restricted Misuse Case Modeling (RMCM), defines templates for specifying misuse cases, security use cases, and mitigation schemes. It aims to address challenges with existing approaches, such as precisely eliciting security threats, capturing control flows, and separating mitigation specifications. The approach was applied to model security requirements for a case study project. An empirical study evaluated how well the approach supported precise definition of security requirements.
The document discusses SQL injection attacks, which take advantage of un-sanitized input in web applications to execute malicious SQL commands. It describes various types of SQL injection attacks, including piggybacked queries, stored procedures, union queries, and blind SQL injection. The document also covers mitigation techniques used to prevent SQL injection attacks.
In this digital era, organizations and industries are moving towards replacing websites with web applications for many obvious reasons. With this transition towards web-based applications, organizations and industries find themselves surrounded by several threats and vulnerabilities. One of the largest concerns is keeping their infrastructure safe from attacks and misuse. Web security entails applying a set of procedures and practices, by applying several security principles at various layers to protect web servers, web users, and their surrounding environment. In this paper, we will discuss several attacks that may affect web-based applications namely: SQL injection attacks, cookie poisoning, cross-site scripting, and buffer overflow. Additionally, we will discuss detection and prevention methods from such attacks.
IRJET- Testing Web Application using Vulnerability ScanIRJET Journal

SOURCE CODE ANALYSIS TO REMOVE SECURITY VULNERABILITIES IN JAVA SOCKET PROGR...IJNSA Journal
This paper presents the source code analysis of a file reader server socket program (connection-oriented
sockets) developed in Java, to illustrate the identification, impact analysis and solutions to remove five
important software security vulnerabilities, which if left unattended could severely impact the server
running the software and also the network hosting the server. The five vulnerabilities we study in this
paper are: (1) Resource Injection, (2) Path Manipulation, (3) System Information Leak, (4) Denial of
Service and (5) Unreleased Resource vulnerabilities. We analyze the reason why each of these
vulnerabilities occur in the file reader server socket program, discuss the impact of leaving them
unattended in the program, and propose solutions to remove each of these vulnerabilities from the
program. We also analyze any potential performance tradeoffs (such as increase in code size and loss of
features) that could arise while incorporating the proposed solutions on the server program. The
proposed solutions are very generic in nature, and can be suitably modified to correct any such
vulnerabilities in software developed in any other programming language. We use the Fortify Source
Code Analyzer to conduct the source code analysis of the file reader server program, implemented on a
Windows XP virtual machine with the standard J2SE v.7 development kit
website vulnerability scanner and reporter research paperBhagyashri Chalakh
This document discusses developing a website analysis tool to improve vulnerability scanning and reporting. It proposes using deep neural networks to enhance the accuracy of vulnerability scanners. It first reviews existing vulnerability scanners like Nessus, Acunetix, and OWASP ZAP and their capabilities. It then discusses how vulnerability scanners use techniques like crawling, fuzzing, and machine learning algorithms to detect vulnerabilities. The proposed tool aims to reduce false positives, allow simultaneous scans, and provide clear reports with countermeasure recommendations to better secure websites.
The document discusses various types of attacks against web applications, including SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). SQL injection occurs when untrusted user input is inserted into SQL queries without proper validation/sanitization, allowing attackers to alter queries for unauthorized data access or modification. XSS happens when a web app displays user input without sanitization, allowing scripts to be injected and run in a victim's browser in the context of the vulnerable site. CSRF tricks the victim's browser into unknowingly executing unauthorized commands by forging legitimate requests. Examples are provided for each type of attack.
Devoid Web Application From SQL Injection AttackIJRESJOURNAL
ABSTRACT: The entire field of web based application is controlled by the internet. In every region, World Wide Web is hugely necessary. So, network assurance is badly assuring job for us. Several kind of attacker or application programmer is attempting to split the immunity of information and destroy the instruction composed in the database. The SQL Injection Attack is very large safety measure risk in that present day. The indicated attacks allow to attacker’ s unlimited access from the database or still authority of database those determine web based application. That manages conscious and secret records and put the injurious SQL query put to modify the expected function. Many database reviewer and theorist give distinct concept to avoid regarding SQL Injection Attack. But no one of the concept is completely adaptable to. This research introduces a latest framework to protecting web based application from the SQL Injection Attack. Introduced framework i.e. present in this research is based on two techniques known as SQM (SQL Query Monitor) and Sanitization Application. That is the two ways filter program which analyses the user query and generate a separate key for user before it is sent to the application server. Several aspects of SQL Injection Attack are also discussed in that research.
The document discusses application threat modeling for a college library website. It describes decomposing the application into external dependencies, entry points, assets, and trust levels. It then covers determining and ranking threats using STRIDE and ASF categorizations. The document outlines identifying security controls and countermeasures to address vulnerabilities. It provides steps for threat analysis and defining mitigation strategies.
Now-a-days the world of information era, we can get information just our single click by using Web
application. Web applications are popular due to the ubiquity of web browsers, and the convenience of
using a web browser as a client, sometimes called a thin client. It are playing a major role in this, every
organization are mapping their business from a room to the world with the help of these Web Application.
It consist of a three tier structural design where database is in the third pole, which is the most valuable
assets in any organization, as the adaptation of web applications are increases day by day, various attacks
are possible increasing day by day. An attack which is directly compromises the database that is most
threatening attack is called SQL injection. There are various Vulnerability scanners has been proposed to
deal with this attack, but none of them are able to detect SQLI completely. In my tools have the accuracy
ratio very less as well as they produce a high rate of false positive, apart from that all these tools take
much time to scan. To avoid these problem and detect SQL completely we are presenting a NVS that is
Network Based Vulnerability Scanner approach this provides a better coverage and with no false positive
with a short span of time.
Electronic voting machines are becoming more popular as they help avoid invalid votes and reduce counting time and costs. The machines use a microcontroller to make voting simple and easy to operate. Voter confidence in the flawless working of electronic voting machines is increasing as their use becomes more widespread throughout the country.

SOURCE CODE ANALYSIS TO REMOVE SECURITY VULNERABILITIES IN JAVA SOCKET PROGR...IJNSA Journal
This paper presents the source code analysis of a file reader server socket program (connection-oriented
sockets) developed in Java, to illustrate the identification, impact analysis and solutions to remove five
important software security vulnerabilities, which if left unattended could severely impact the server
running the software and also the network hosting the server. The five vulnerabilities we study in this
paper are: (1) Resource Injection, (2) Path Manipulation, (3) System Information Leak, (4) Denial of
Service and (5) Unreleased Resource vulnerabilities. We analyze the reason why each of these
vulnerabilities occur in the file reader server socket program, discuss the impact of leaving them
unattended in the program, and propose solutions to remove each of these vulnerabilities from the
program. We also analyze any potential performance tradeoffs (such as increase in code size and loss of
features) that could arise while incorporating the proposed solutions on the server program. The
proposed solutions are very generic in nature, and can be suitably modified to correct any such
vulnerabilities in software developed in any other programming language. We use the Fortify Source
Code Analyzer to conduct the source code analysis of the file reader server program, implemented on a
Windows XP virtual machine with the standard J2SE v.7 development kit
website vulnerability scanner and reporter research paperBhagyashri Chalakh
This document discusses developing a website analysis tool to improve vulnerability scanning and reporting. It proposes using deep neural networks to enhance the accuracy of vulnerability scanners. It first reviews existing vulnerability scanners like Nessus, Acunetix, and OWASP ZAP and their capabilities. It then discusses how vulnerability scanners use techniques like crawling, fuzzing, and machine learning algorithms to detect vulnerabilities. The proposed tool aims to reduce false positives, allow simultaneous scans, and provide clear reports with countermeasure recommendations to better secure websites.
The document discusses various types of attacks against web applications, including SQL injection, cross-site scripting (XSS), and cross-site request forgery (CSRF). SQL injection occurs when untrusted user input is inserted into SQL queries without proper validation/sanitization, allowing attackers to alter queries for unauthorized data access or modification. XSS happens when a web app displays user input without sanitization, allowing scripts to be injected and run in a victim's browser in the context of the vulnerable site. CSRF tricks the victim's browser into unknowingly executing unauthorized commands by forging legitimate requests. Examples are provided for each type of attack.
Devoid Web Application From SQL Injection AttackIJRESJOURNAL
ABSTRACT: The entire field of web based application is controlled by the internet. In every region, World Wide Web is hugely necessary. So, network assurance is badly assuring job for us. Several kind of attacker or application programmer is attempting to split the immunity of information and destroy the instruction composed in the database. The SQL Injection Attack is very large safety measure risk in that present day. The indicated attacks allow to attacker’ s unlimited access from the database or still authority of database those determine web based application. That manages conscious and secret records and put the injurious SQL query put to modify the expected function. Many database reviewer and theorist give distinct concept to avoid regarding SQL Injection Attack. But no one of the concept is completely adaptable to. This research introduces a latest framework to protecting web based application from the SQL Injection Attack. Introduced framework i.e. present in this research is based on two techniques known as SQM (SQL Query Monitor) and Sanitization Application. That is the two ways filter program which analyses the user query and generate a separate key for user before it is sent to the application server. Several aspects of SQL Injection Attack are also discussed in that research.
The document discusses application threat modeling for a college library website. It describes decomposing the application into external dependencies, entry points, assets, and trust levels. It then covers determining and ranking threats using STRIDE and ASF categorizations. The document outlines identifying security controls and countermeasures to address vulnerabilities. It provides steps for threat analysis and defining mitigation strategies.
Now-a-days the world of information era, we can get information just our single click by using Web
application. Web applications are popular due to the ubiquity of web browsers, and the convenience of
using a web browser as a client, sometimes called a thin client. It are playing a major role in this, every
organization are mapping their business from a room to the world with the help of these Web Application.
It consist of a three tier structural design where database is in the third pole, which is the most valuable
assets in any organization, as the adaptation of web applications are increases day by day, various attacks
are possible increasing day by day. An attack which is directly compromises the database that is most
threatening attack is called SQL injection. There are various Vulnerability scanners has been proposed to
deal with this attack, but none of them are able to detect SQLI completely. In my tools have the accuracy
ratio very less as well as they produce a high rate of false positive, apart from that all these tools take
much time to scan. To avoid these problem and detect SQL completely we are presenting a NVS that is
Network Based Vulnerability Scanner approach this provides a better coverage and with no false positive
with a short span of time.

This document summarizes a research paper that proposes a Network Vulnerability Scanner (NVS) to detect SQL injection attacks in web applications. The NVS crawls web applications to generate URLs, sends simulated SQL injection attack payloads to those URLs, analyzes the responses to detect vulnerability patterns without false positives, and generates a report of vulnerable URLs. It analyzes responses faster and with higher coverage than existing vulnerability scanners by distributing the work across multiple connected systems in a network using Remote Method Invocation. The proposed NVS approach detects SQL injections more accurately and quickly than prior tools.

NVS crawls web applications to generate URLs, sends simulated SQL injection attack payloads to URLs, analyzes responses for SQL injection patterns, and generates a report of vulnerable URLs. It uses multiple connected systems to simulate attacks in parallel, aiming to improve on existing vulnerability scanners that are slower with higher false positive rates when scanning large web applications from a single system. The proposed approach is implemented in Java using a MySQL database to store URLs and attacks.
Security against Web Application Attacks Using Ontology Based Intrusion Detec...IRJET Journal
The document presents a proposed ontology-based intrusion detection system to provide security against web application attacks. The system aims to address limitations of existing signature-based intrusion detection systems, such as high false positive and negative rates. The proposed system uses an ontology created with Protege to model web application attacks, vulnerabilities, threats and security controls. Rules are also defined to allow the system to predict and classify attacks based on the ontology. The system architecture includes components for system analysis, interface, rule engine, ontology generation and a knowledge base. The system is evaluated on its ability to detect common web attacks like SQL injection, cross-site scripting and buffer overflow attacks.
This document discusses using Python to build a web application vulnerability scanner called SCANSCX. SCANSCX uses Python tools like AST, CFG, Flask and Django to analyze source code and detect vulnerabilities like command injection and cross-site scripting (XSS). It parses web applications into abstract syntax trees and control flow graphs to identify vulnerabilities. The scanner was tested on purposefully vulnerable applications and was able to correctly detect the vulnerabilities. SCANSCX can scan applications built with both Flask and Django frameworks.
Deployment of Reverse Proxy for the Mitigation of SQL Injection Attacks Using...ijcisjournal
Internet has eased the life of human in numerous ways, but the drawbacks like the intrusions that
are attached with the Internet applications sustains the growth of these applications. Hackers find
new methods to intrude the applications and the web application vulnerability reported is increasing
year after year. One such major vulnerability is the SQL Injection attacks (SQLIA). Since SQLIA
contributes 25% of the total Internet attacks, much research is being carried out in this area. In this
paper we propose a method to detect the SQL injection. We deploy a Reverse proxy that uses the
input-data cleansing algorithm to mitigate SQL Injection Attack. This system has been tested on
standard test bed applications and our work has shown significant improvement in detecting and
curbing the SQLIA.

The document describes an approach called PXpathV that detects XPath injection vulnerabilities in web applications. PXpathV works by intercepting XPath expressions, analyzing them to identify user input parameters, generating an XML file with the parameters, and validating the XML file against a schema to detect any injection attempts. An evaluation of PXpathV showed it increased response times but successfully identified injection vulnerabilities that would otherwise not be detected.
PXpathV: Preventing XPath Injection Vulnerabilities in Web Applicationsijwscjournal
Generally, most Web applications use relational databases to store and retrieve information. But, the growing acceptance of XML technologies for documents it is logical that security should be integrated with XML solutions. In a web application, an improper user inputs is a main cause for a wide variety of attacks. XML Path or XPath language is used for querying information from the nodes of an XML document. XPath
Injection is an attack technique, much like SQL injection, exists when a malicious user can insert arbitrary XPath code into form fields and URL query parameters in order to inject this code directly into the XPath query evaluation engine. Through the crafted input a malicious user would bypass authentication or to
access restricted data from the XML data source.Hence, we proposed an approach to detect XPath injection attack in XML databases at runtime. Our approach intercept XPath expression and parse the XQuery expression to find the inputs to be placed in the expression. The identified inputs are used to design
an XML file and it would be validated through a schema.

This document describes a web vulnerability scanner created by students at D.Y.Patil College of Engineering. The scanner focuses on detecting and preventing common web vulnerabilities like SQL injection, cross-site scripting, file inclusions, and OS command injection. It was developed using the waterfall model, with phases for requirements gathering, system design including UML diagrams, and implementation. The motivation was that cyber attacks cost the global economy over $400 billion annually, so an automatic tool is needed to identify vulnerabilities in web applications.
This document summarizes a survey of cloud-based secure web applications. It begins with an introduction to cloud computing and the security risks of web applications. It then presents two tables: 1) a comparison of related work on web application security that analyzes the attacks, algorithms, languages, models, studies, and test cases used; and 2) a comparison of Python to PHP and Ruby programming languages in terms of their version, purpose, creator, influences, popular sites built with each, usability, and ease of learning. The document concludes that there is a need for solutions that allow users to securely test websites for vulnerabilities in the cloud.
Cross Site Scripting Attacks and Preventive MeasuresIRJET Journal
This document summarizes cross-site scripting (XSS) attacks and preventive measures. It discusses that XSS attacks allow attackers to inject malicious scripts into web pages through inputs like search fields or comment boxes. There are three main types of XSS attacks: non-persistent reflect XSS through query parameters, persistent stored XSS by storing scripts on servers, and DOM-based XSS using document object model functions. Input validation and code filtering are effective preventive measures. The document also proposes a script filtering algorithm to sanitize inputs and prevent execution of malicious scripts.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

ABSTRACT
Web applications become an important part of our daily lives. Many other activities are relay on the
functionality and security of these applications. Web application injection attacks, such as SQL injection
(SQLIA), Cross-Site Scripting (XSS) and Cross-Site Request Forgery (XSRF) are major threats to the
security of the Web Applications. Most of the methods are focused on detection and prevention from these
web application vulnerabilities at Run Time, which need manual monitoring efforts. Main goal of our work
is different in the way it aims to create new systems that are safe against injection attacks to begin with,
thus allowing developers the freedom to write and execute code without having to worry about these
attacks. In this paper we present SQL Attack Scanner (SQLAS) a Tool which can detect & prevent SQL
injection Attack in web applications. We analyzed the performance of our proposed tool SQLAS with
various PHP web applications and its results clearly determines the effectiveness of detection and
prevention of our proposed tool. SQLAS scans web applications offline, it reduces time and manual effort
due to less overhead of runtime monitoring because it only focus on fragments that are vulnerable for
attacks. We use XAMPP for client server environment and developed a TESTBED on JAVA for evaluation
of our proposed tool SQLAS.

1. INTRODUCTION
Web application security is primary issue in today’s web world. The Web serves as a convenient
portal between end-users and company resources such as user accounts. Web application permits
user to link up with server by data exchange, which might be access web’s database or other
resources of system with the help of different browsers. Such applications that facilitate a rich
online experience (personal financing, social networking, business transactions, etc) are
burdened with securing the privacy of sensitive data while permitting data exchange. Inputs to
web application are known as Injection Attack if they belong to vulnerable category, these inputs
include XSS and SQL [1]. SQL and XSS are top most web application security thread listed by
OWASP in 2010[1]. Attack happens when

Injection attacks happens once input passes from the web browser to the web server application,
probably onto the database and even back to the user's browser; and this input includes malicious
values/scripts that may alter the activities of the online web application and produced surprising
results. A typical winning attack begins within the client-side browser wherever an internet
application is rendered, giving AN assailant chance to input malicious information via the
browser. This information is then sent to the server, wherever it should reach the back-end
information via a query, leading to a SQL Injection attack, or it should be sent back to the
attacker's client-side browser for execution, leading to a Cross-Site Scripting Attack. These
attacks become susceptible information or provide unauthorized access to system resources
forthwith.
Attacks will abuse on an innocent user once the previously stored malicious information is
retrieved and becomes a part of a query or the rendered web content. One extreme measure to
counter such attacks would be to prohibit any user input to net applications; such a measure is
impractical for any net application that interacts with end-users. an internet application while not
input has terribly restricted functionality; it doesn't have the power to query the user so as to show
pertinent info. Thus, there's no access to back-end databases to retrieve personal info (e.g., a
checking account balance) neither is there the aptitude to perform transactions (e.g., on-line bill
pay). Therefore, the first measure for countering injection attack involves characteristic attainable
malicious inputs and fixing them, so rendering them benign. this is often named because the
cleaning methodology.
In this research work we focused on the detection and prevention of SQL injection vulnerability
in web applications written in PHP. We choose SQL injection and PHP web applications for
several reasons. First, many web applications have SQL injection vulnerability. SQL injection
attack could combine with other attach techniques, which occurs very frequently, and could cause
huge financial losses for organizations and companies. In 2013, OWASP Top Ten Project rated
SQL injection as the number one attack [1]. Second, PHP is a popular web development
programming language, but web applications developed in PHP are the most vulnerable web
applications according to the study conducted by Positive Technologies [2]. The study compared
the security vulnerabilities of web sites on PHP, ASP.NET, and Java caused by inappropriate
software implementation. It showed that 81% of sites in PHP contain critical security
vulnerabilities, and 91% contained medium-risk vulnerabilities. Last, but not the least, the tool
developed in the research can be used for educational purpose. Students can use this tool to check
SQL injection vulnerability on their course projects.
This paper is organized as follows. Section two, includes some related work in web application
Vulnerability domains. Section three, discusses the approach to web application security,
provides a brief overview of the proposed method and explains the model. In Section four, we
explain the proposed system. In section five, we evaluate the performance of SQLAS as discussed
followed by a conclusion and future work.
2. LITERATURE SURVEY
This work is expounded to some areas of active analysis, such as rationalization and victimization
specifications for bug finding, vulnerability analysis, and attack detection for web applications.
during this section, we tend to describes the foremost seminal and interesting works in these areas

with the intent of highlight the most trends and achievements in these areas of research, and to
position the work drawn throughout this paper at intervals the context of previous work. A tool
WebSSARI [3], revealed in 2004, and is the key work that applies static taint propagation
analysis to finding security vulnerabilities in PHP applications. WebSSARI targets three specific
varieties of vulnerabilities: XSS, SQL Injection, and general script injection. WebSSARI used
flow-sensitive, intra-procedural analysis supported a lattice model and sort state. Previously
discussed all the PHP language is extended with two type-qualifiers, specifically tainted and
unblemished, and therefore the tool keeps track of the type-state of variables. The tool uses three
user-provided files, known as prelude files: a file with preconditions to any or all sensitive
functions (i.e., the sinks), a file with post conditions for acknowledged cleansing functions, and a
file specifying all attainable sources of doubtful input. So as to undamaged the contaminated
information, the information needs to be processed by a cleansing routine or to be forged to a
secure kind. Once the tool determines that tainted information reaches sensitive functions, it
mechanically inserts runtime guards, that area unit cleansing routines.
Another approach conjointly supported static taint propagation analysis, to the detection of input
validation vulnerabilities in PHP applications is delineated in [4, 5]. A flow sensitive, inter-
procedural and context-sensitive information flow analysis is employed to spot intra-module XSS
and SQL injection vulnerabilities. These approaches are imposed in a very tool, known as PIXY
that is that the most complete static PHP analyzer in terms of the PHP options shapely. To the
simplest of our information, it's the sole publicly-available tool for the analysis of PHP-based
applications
The work by Xie and author [6], revealed in 2006, describes a three-level approach to search out
SQL injection vulnerabilities in PHP applications. In beginning symbolic execution is used to
model the impact of statements within the fundamental blocks of intra-procedural management
Flow Graphs (CFGs). Then, the ensuing block outline is employed for intra procedural analysis,
wherever a typical reachable analysis is employed to achieves goal. In conjunction with substitute
data, every block outline contains a group of locations that were unblemished within the given
block. The block summaries area unit composed to come up with a perform outline, that contains
the pre- and post-conditions of perform.
The research by Su associated Wassermann [7] is another example of an approach which uses a
model of “normality” to find injection attacks, like XSS, XPath injection, and shell injection
attacks. However, this implementation, known as SqlCheck is meant to find SQL injection attacks
solely. The approach works by trailing substrings from user input through the program execution.
The trailing is enforced by augmenting the string with special characters, which spot the
beginning and so the finish of every substring. Then, dynamically-generated queries area unit
intercepted and checked by a changed SQL programmed.
Recently, applicability and scalability of model checking approaches in the domain of web
applications started being explored by the research community. In particular, in 2008, a work
describing the QED system was published [8]. QED identifies XSS and SQL injection
vulnerabilities that arise as a result of the interaction of multiple modules of a servlet-based web
application. The system uses explicit model checking to find XSS and SQL injection
vulnerabilities and uses a number of heuristics to scale the approach to large applications. To find
vulnerability, the tool needs to be supplied with a specification of a vulnerability (written in PQL)
and a set of inputs to the application under test. Then, the Java PathFinder [15] model checker is
4. International Journal of Security, Privacy and Trust Management (IJSPTM) Vol 4, No 1, February 2015
24
used to execute the application using a sequence of user requests that are generated based on user
input values provided by an analyst. Vulnerability is found when a match to a PQL query is found
by the model checker. In general, the approach proposed in this work can be applied to detect
vulnerabilities other than taint-based ones if an analyst is able to provide the tool with a
specification of a vulnerability specifying patterns of events (such as program method calls) that
need to occur on a program path.
Another example is the work by Paleari et al. [9] that takes a look at a new and unexplored class
of vulnerabilities in the domain of web applications. In particular, the paper looks at race
condition vulnerabilities that can arise in web applications interacting with a back-end database.
A race condition may occur in a multi-threaded environment between two database queries if data
accessed by one query can be modified by another one. In a multi-threaded application, the
shared data in the database might not be consistent between the two queries if code that was
designed to be executed sequentially is executed concurrently. The authors propose a dynamic
approach to identify this class of vulnerabilities, in which all database queries generated by a
running program are logged and analyzed (offline) for data dependencies.
A good example of an approach based on a model of expected behavior is the work of Halfond
and Orso, whose tool is called AMNESIA [10]. AMNESIA is particularly concerned with
detecting and preventing SQL injection attacks for Java-based web applications. In the static
analysis phase, the tool builds a conservative model of predictable SQL queries. Then, at
execution-time, dynamically-generated queries are checked against the resulting model to identify
instances that violate the intended structure of a query. AMNESIA uses Java String Analysis
(JSA) [19], a static analysis technique, to build an automata-based model of the set of legitimate
strings that a program can produce at given points in the code. AMNESIA also leverages the
approach proposed by Gould, Su, and Devanbu [11] to statically check type correctness of
dynamically-generated SQL queries.
SQL DOM [12] uses database queries encapsulation access to databases confidentially. SQL
DOM use a type-checked API which found query building process is efficient. Consequently by
API they apply coding best practices such as input filtering and strict user input type checking.
The disadvantage of the methods is that developer should learn new programming paradigm or
query-development process. SQL-IDS [13] focused on writing specifications for the internet
application that explain the intended configuration of SQL statements that are produced by the
application, and in automatically monitoring the execution of these SQL statements for violations
with respect to these specifications.
A proxy filtering system that intensifies input validation rules on the data flowing to a Web
application is called Security Gateway [14]. In this technique for transferring parameters from
web-page to application server, developers should use Security Policy Descriptor Language
(SPDL). So developer should know which data should be filtered and also what patterns should
apply to the data. SQLPrevent [15] is exists of a Hyper Text Transfer Protocol (HTTP) request
interceptor. Core data flow is corrected when SQLPrevent is installed into a web server. The
Hyper Text Transfer Protocol (HTTP) requests are saved into the existing thread-local storage.
Then, SQL interceptor intercepts the SQL queries that are made by internet application and send
them to the SQLIA detector module. Thus, Hyper Text Transfer Protocol request from threads
local storage is fetched and analyzed to determine whether it restrains a SQLIA. The malicious
SQL statement would be prevented to be sent to database, if it is doubtful to SQLIA. Rather than
5. International Journal of Security, Privacy and Trust Management (IJSPTM) Vol 4, No 1, February 2015
25
this there may many other modern methods has also been proposed for preventing SQLI attacks
[16], [17], [12], [18], [19], [20], [21].
Swaddler [22] is a distinctive way to notice the anomaly-based attacks in internet applications.
Swaddler analyses the inside status of an internet application and discovers the connections
between the application’s very important execution points and also the application’s internal
state. With this, Swaddler is capable to acknowledge attacks that commit to get associate
application in associate inconsistent, abnormal state, like violations of the projected work flow of
an internet application. Swaddler could be a unusual approach to the detection of attacks against
internet applications. The approach relies on a close characterization of the inner state of an
internet application, by suggests that of variety of anomaly models. A lot of exactly, the inner
state of the appliance is monitored throughout a learning part. Throughout this part the approach
derives the profiles that describe the traditional values for the application’s state variables in
important points of the application’s elements. Then, throughout the detection part, the
application’s execution is monitored to identify abnormal states. The approach has been enforced
by instrumenting the PHP interpreter and has been valid against real-world applications.
Zhendong Su [23] presents the primary formal definition of command injection attacks within the
context of internet applications, and provides a sound and complete rule for preventing those
supported context-free grammars and compiler parsing techniques. Our key examination is that,
for AN attack to succeed, the input that gets propagated into the info query or the output
document should amendment the meant grammar structure of the query or document. This
definition and rule are general and apply to several varieties of command injection attacks. This
approach is confirmative with SQLCHECK, An execution for the setting of SQL command
injection attacks. They evaluated SQLCHECK on real-world internet applications with
consistently compiled real-world attack information as input. SQLCHECK made no false
positives or false negatives, incurred low runtime overhead, and applied straightforwardly to
internet applications written in numerous languages.
3. PROPOSED METHOD
In this paper we are proposing a new tool for SQL injection Detection and Prevention mechanism
for the PHP web applications. However our planned technique will be equally effective for each
simple and complex data structure. The SQL Attack Scanner (SQLAS) is a tool to detect and
prevent attacks in PHP web applications, SQLAS is simple and really easy to implement. During
this technique all the data validations rules are going to be during a secure place. The data
validation rules also will be organized into some XML format and that they are referred to as
XML-rules. Whenever server receives any input from client the server can verify the whole XML
script supported the verification rules already written within the server.
The main distinction between SQLAS and therefore the alternative SQL injection detection and
prevention methods is that our method validates the complete incoming wed application data at a
time. Moreover the XML-rules are going to be written and stored on an individual basis. That
creates the developer task easier, what they have to do is simply to verdict the validation task for
validating any web application data. Presently one validation function written for an application.
The validation data can verify the incoming XML scripts supported the foundations written
within the XML-rules. For every application the incoming XML scripts can have registered
6. International Journal of Security, Privacy and Trust Management (IJSPTM) Vol 4, No 1, February 2015
26
format for various user requests. XML-rules are going to be written on an individual basis for
every kind of incoming XML scripts and therefore the incoming XML script should succeed the
validation method. This method can primarily divide the data validation of a web application
from the application development division. The developer at present ought not to worry about the
SQL injection attacks and data validity. The validation parts of data are going to be maintained by
a separate cluster which can manage the XML-rules. This is often conjointly useful as a result of
the traditional web developers are going to be utterly unaware regarding the safety rules of the
application.
Figure 2.1 explains the essential flow of SQLAS. Once user can submit any query then rather
than submitting straightforward data, it'll submit all the data in XML format. Essentially it'll send
one XML script to the server. The server can receive the XML script, analyze it and obtain the
initial data.
Fig.: 2.1 Flow Graph of proposed SQLAS
The Proposed SQLAS algorithm is as follow:
Algorithm 1: Algorithm SQLAS
Input: A web application.
Output: List of possible SQL injection threats.
• STEP 1: Select the Web page from web application folder.
• STEP 2: Convert it into XML script format (which is already known by server)
• STEP 3: Send this XML script to server
7. International Journal of Security, Privacy and Trust Management (IJSPTM) Vol 4, No 1, February 2015
27
• STEP 4: Server receives XML script and checks its validity with pre-specified XML-
Rules.
• STEP 5: Each SQL statement can have variables which are static, dynamic or composite.
For each SQL statement do the following operations:
if if any variable is composite then
for all composite variables in the statement do
recursively verify the composite variable until all its dependent variables are either
static or dynamic.
end for
if any of the dependent variable found as dynamic then
the SQL statement is may not be safe.
else
the SQL statement is safe.
end if
else if if any variable is dynamic then
the statement is may not be safe.
else
if all variables are static the statement is safe
end if
• STEP 6: if SQL statement is safe or valid than execute the SQL query.
• STEP 7: otherwise discard the SQL query.
• STEP 8: Exit.
4. EXPERIMENTAL ANALYSIS
For the Experimental analysis of proposed method we developed a Testbed, which is coded in
JAVASCRIPT and able to run SQL queries of web Applications. To create Client server
environment in PHP web application we used XAMPP 1.8.2 version. XAMPP is a tool , it is free
and open source cross-platform web server solution stack package, consisting mainly of
the Apache HTTP Server, My SQL database, and interpreters for scripts written in
the PHP and Perl programming languages.
To evaluate the effectiveness of SQLAS : the SQL Injection Testbed was used. Fig 3 shows
representation of Testbed. The SQL Injection Testbed has been used for evaluating various web
applications developed in PHP. It examined number of test cases on an open source web
applications. It contains two types of test cases: the XML rules from which SQL queries get
validate and the other is Return error message by the server. Table 1 summarizes the Web
applications. The first column contains the names of the Web applications. The second column
contains its descriptions.

5. CONCLUSION
In this work, we have converse about the concept of SQL injection which has become a common
problem of all the web-based applications. We have summarized a variety of techniques existing
to protected data from SQL injections, which can modify the program behavior permitting the
attacker to retrieve and modify the database information. In this paper our research work presents
a tool called SQLAS which can detect the vulnerability spots in the source code. Also, it provides
the developer with an additional option of checking the syntax. Detection is done by validating
the SQL queries using general validation procedure based on XML rules and the nature of the
injection type. Any possibility of vulnerability or violation of the analyzed nature is reported as a
warning message or error message to the developer. The warning message or error message
9. International Journal of Security, Privacy and Trust Management (IJSPTM) Vol 4, No 1, February 2015
29
includes the injection type description and the line number of vulnerable spot in the source code.
The concepts explained in this work assist the Developer to modify the SQL statements and make
the code attack free. We conclude by highlighting the robust features of the efficient tool SQLAS,
which can detect the error during the development statically and can protect web applications
from the future SQL injection.
We believe that the ideas presented in this research work can be further extended to include new
injection types. This work also paves way for the development of vulnerability detection services,
which can be used by developers to detect vulnerability spots in the source code. We feel the area
of SQL injection vulnerabilities is wide open for research and we conclude by suggesting that this
step to verify the code against SQL injection vulnerabilities can be added in the checklist for
performance review in the static code analysis of the source code of data driven applications.
