Cross-Site Scripting Explained - Part 9: CSS String Injection
 
04:48
Author: Jeremy Druin Twitter: @webpwnized Description: In this video we look at injecting cross site script into the stylesheet context. The example comes from the set-background color page in Mutillidae. The example is trivial but the point is that cross site scripting can occur in any context. Developers need to encode all output even when the output is not occurring in the standard HTML context. The software used in the demo is the OWASP Mutillidae II Web Pen-Test Practice Application. Mutillidae is a free, open source web application with vulnerabilities added to allow pen testers and security enthusiasts to test for defects. Mutillidae can be downloaded from Sourceforge. Updates are tweeted to @webpwnized. Thank you for watching. Please support this channel. Up vote, subscribe or even donate by clicking "Support" at https://www.youtube.com/user/webpwnized!

19:01
Author: Jeremy Druin Twitter: @webpwnized Reference(s): http://blog.portswigger.net and http://www.thespanner.co.uk/2014/03/21/rpo/ (Gareth Heyes) Description: Path relative style sheet injection is a type of cross site scripting that takes advantage of the different methods web servers and web browsers use to interpret file path to relative resources such as stylesheets and scripts. The vulnerability was implemented in Mutillidae II web penetration testing environment. This video describes how to take advantage of the Styling with Mutillidae page using an exploit crafted from the attack described by Portswigger et al. Path relative style sheet injection (aka relative path overwrite) is described on the Portswigger Blog (Burp-Suite) with reference to Gareth Heyes who wrote about it on his blog.

XSS Cross Site Scripting Demonstration
 
05:55
Cross-site scripting ('XSS' or 'CSS') is an attack that takes advantage of a Web site vulnerability in which the site displays content that includes un-sanitized user-provided data. For example, an attacker might place a hyperlink with an embedded malicious script into an online discussion forum. That purpose of the malicious script is to attack other forum users who happen to select the hyperlink. For example it could copy user cookies and then send those cookies to the attacker. The Script Injection video should be watched before this video for greater understanding.

Revisiting XSS Sanitization
 
01:02:29
By Ashar Javed "The online WYSIWYG ""What You See Is What You Get"" editors or rich-text editors are nowadays an essential component of the web applications. They allow users of web applications to edit and enter HTML rich text (i.e., formatted text, images, links and videos etc) inside the web browser window. This talk will first demonstrate how to break the top 25 online WYSIWYG editors powering thousands of web applications. We show XSS bypasses for top WYSIWYG editors like TinyMCE, Jive, Froala, CKEditor etc. We will share stories of how we were able to XSSed WYSIWYG editors of sites like Twitter, Yahoo Email, Amazon, GitHub, Magento, and CNET etc. After breaking almost all WYSIWYG editors in the wild, this talk will present a sanitizer (very easy to use, effective and practical solution) which is based only on '11 chars + 3 regular expressions' and will show how it will safe you from an XSS in HTML, attribute, script (includes JSON context), style and URL contexts."

Ryan Seddon: So how does the browser actually render a website | JSConf EU 2015
 
29:34
We all take for granted that when we push enter in the browsers address bar, magic happens. The browser gets our HTML, that intern requests all the dependencies, insert magic, other things happen and then we have our site rendered. Simple, right, right… Like many people as I’ve progressed in my career, building for the web, I’ve become curious as to how the browser does what it does. What makes it tick, how it turns a string of HTML into a data structure, how CSS & JavaScript come into play. Things like render tree, style recalculation, paints, reflows, all alien words will start to make sense by the end of this talk. Suddenly you’ll understand why people recommend you place script tags at the bottom of the document, inlining critical CSS & all sorts of other performance techniques. Intro music by @halfbyte

Unfortunately that last word, "scripting", has ensured that our collective understanding of injection attacks remains fundamentally tied up with JavaScript. Cross-site _styling_ is actually more capable than you might expect; it's quite possible to exfiltrate sensitive data (like passwords!) without any script at all. This talk will walk through some of the cleverly malicious activity that CSS makes possible, and discuss some mechanisms for mitigating the risk that your sites and applications might be effected."

The Forgotten CSS Position
 
07:28
Everyone knows how to use relative, absolute, and fixed positioning in CSS, but most people don't even know about the amazing sticky position. Sticky position is a unique hybrid between relative and fixed position and makes creating elements that only act liked fixed elements after they are scrolled to a certain point incredibly easy. This used to be something that could only be accomplished in JavaScript, but sticky position makes it possible in CSS, and is much better for web performance.
