Cross Site Scripting Defense Presentation
Cross site scripting (XSS) is a type of computer security vulnerability typically found in web applications, but in proposing defensive measures for cross site scripting the websites validate the user input and determine if they are vulnerable to cross site scripting. The major considerations are input validation and output sanitization.
There are lots of defense techniques introduced nowadays and even though the coding methods used by developers are evolving to counter attack cross site scripting techniques, still the security threat persist in many web applications for the following reasons:
• The complexity of implementing the codes or methods.
• Non-existence of input data validation and output sanitization in all input fields of the application.
• Lack of knowledge in identifying hidden XSS issues etc.
This proposed project report will briefly discuss what cross site scripting is and highlight the security features and defense techniques that can help against this widely versatile attack.
Cross site scripting attacks and defenses
Cross-site scripting (XSS) is an injection attack where malicious scripts are injected into otherwise trusted sites. There are three main types of XSS attacks: reflected XSS occurs via URLs, stored XSS occurs when scripts are stored in a database and delivered to users, and DOM-based XSS modifies the DOM environment. XSS attacks can lead to issues like session hijacking, phishing, and port scanning. Developers can prevent XSS by validating and encoding untrusted data, and using HTTP-only and secure flags for cookies.
Understanding Cross-site Request Forgery
This document provides an overview of cross-site request forgery (CSRF) attacks. It discusses how CSRF works, forcing victims to perform actions on a website without their knowledge. Common defenses like using nonces or CAPTCHAs are described. The document also covers how to validate if an issue is truly a CSRF vulnerability and lists some example attack vectors. Key takeaways emphasize the importance of validating any potential CSRF issue affects state, is sensitive, and has non-unique requests.
Cross Site Scripting ( XSS)
Cross Site Scripting (XSS) is a vulnerability that allows malicious users to insert client-side code into web pages that is then executed by a user's browser. This code can steal cookies, access private information, perform actions on the user's behalf, and redirect them to malicious websites. XSS works by having the server display input containing malicious JavaScript from a request. There are different types of XSS attacks, including non-persistent, persistent, and DOM-based attacks. Prevention methods include validating, sanitizing, and escaping all user input on the server-side and client-side. Web vulnerability scanners like Burp Suite can help test for XSS and other vulnerabilities.
Cross site scripting
Cross Site Scripting (XSS) is a type of injection attack where malicious scripts are injected into otherwise benign and trusted websites. XSS has been a top web application vulnerability since 1996. There are three main types of XSS attacks: reflected XSS, stored XSS, and DOM-based XSS. Reflected XSS occurs when malicious scripts come from URLs, while stored XSS happens when scripts are stored on websites. XSS can be used to steal cookies and sessions, redirect users, alter website contents, and damage an organization's reputation. Developers can prevent XSS through input validation, output encoding, and using the HttpOnly flag.

CSRF Basics
Csrf / Xsrf Basics defines CSRF as a type of web application vulnerability that allows a malicious website to send unauthorized requests to a vulnerable website using active sessions of its authorized users. CSRF tricks the victim into loading a page that contains a malicious request, which inherits the victim's identity and privileges to perform an undesired function like changing passwords. CSRF attacks target functions that cause state changes on the server but can also access sensitive data. The synchronizer token pattern is a server-side prevention technique that establishes a token on the server to validate submissions through a corresponding token in a hidden form field, marking tokens as invalid after single use.
Cross Site Request Forgery
Talk on CSRF I gave at work that talks about CSRF, how to prevent it and how frameworks can make prevention nearly automatic.

Reverse proxies & Inconsistency
https://2018.zeronights.ru/en/reports/reverse-proxies-inconsistency/
Modern websites are growing more complex with different reverse proxies and balancers covering them. They are used for various purposes: request routing, caching, putting additional headers, restricting access. In other words, reverse proxies must both parse incoming requests and modify them in a particular way. However, path parsing may turn out to be quite a challenge due to mismatches in the parsing of different web servers. Moreover, request converting may imply a wide range of different consequences from a cybersecurity point of view. I have analyzed different reverse proxies with different configurations, the ways they parse requests, apply rules, and perform caching. In this talk, I will both speak about general processes and the intricacies of proxy operation and demonstrate the examples of bypassing restrictions, expanding access to a web application, and new attacks through the web cache deception and cache poisoning.
Input Validation
Input validation is important to prevent incorrect or invalid values from being entered into an application which could lead to user frustration or security issues. Exceptions handle errors and unexpected conditions during program execution. Common exceptions include ImportError, ValueError, and IOError. The try-except block allows code to be executed within the try statement and exceptions raised to be handled in the except block through predefined or custom exceptions.
P H I S H I N G
Phishing involves tricking individuals into providing personal information through fraudulent emails or websites. Attackers often use technical tricks to make spoofed links and websites appear legitimate. This can lead to identity theft and financial loss if victims provide information like credit card numbers, social security numbers, or passwords. While technical measures can help detect some phishing attempts, a decentralized online criminal network has developed to steal and use personal data for profit through identity fraud.
File upload vulnerabilities & mitigation
This document discusses file upload vulnerabilities, exploitation, and mitigation. It provides 6 cases of how file uploads can be exploited such as through simple uploads without validation or altering content types. Tools mentioned for exploitation include BurpSuite and proxies. The document recommends mitigation techniques like using .htaccess files outside the upload directory, storing uploads outside the server root, not relying on client-side validation, and renaming files with random names. It concludes with offering a proof of concept demonstration.

Web 2.0 Hacking
Automated web application scanners have limitations in conducting comprehensive security assessments due to increasing complexities in web technologies. Scanners struggle with dynamic Ajax code, JavaScript obfuscation, complex session handling, backend APIs, and other emerging techniques. A better approach combines automated scanning with manual testing of known attack vectors, application profiling, input and output validation testing, and fuzzing to identify vulnerabilities beyond low-hanging fruit. Comprehensive security requires assessing how specific applications implement authentication, authorization, error handling, and defensive measures.

The document discusses the science behind runtime application self-protection (RASP) and interactive application security testing (IAST). It describes how RASP works by instrumenting application code to perform dynamic taint analysis, tracking tainted data from inputs and checking for policy violations at sinks like database queries. IAST similarly instruments code but also correlates runtime behavior with attacks to confirm vulnerabilities. The document outlines challenges with taint analysis like under-tainting causing false negatives or over-tainting causing false positives. Both RASP and IAST add overhead, and IAST also has limitations of traditional dynamic application security testing.

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).

Removing Uninteresting Bytes in Software Fuzzing
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.
- These are slides of the talk given at IEEE International Conference on Software Testing Verification and Validation Workshop, ICSTW 2022.
