---Google:"Chrome 18 anti XSS bypass" and feel lucky ;) A while ago I released a bypass for the webkit XSSAuditor in Chrome, I thought I'd honor it with a blog post and discuss another danger the XSSAuditor presents to web application security. This 'danger' of XSS filters has been published in a very popular paper---http://www.collinjackson.com/research/xssauditor.pdf--- about some XSS filters. What I'm doing here is demonstrating whats described. XSSAuditor is part of WebKit's HTML parser and exists to try and mitigate reflected XSS attacks. Unfortunately because of how the auditor operates it can often have quite the opposite effect! In this post I'll explain the situations where XSSAuditor can actually have the adverse effect on a web application's protection against XSS attacks.
