Ra.2 - Blackbox DOM-based XSS Scanner is our approach towards finding a solution to the problem of detecting DOM-based Cross-Site Scripting vulnerabilities in Web-Application automatically, effectively and fast. Ra.2 is basically a lighweight Mozilla Firefox Add-on that uses a very simple yet effective and unique approach to detect most DOM-based XSS vulnerabilities, if not all. Being a browser-add on it is a session-aware tool which can scan a web-application that requires authentication. Ra.2 uses custom collected list of XSS vectors which has been heavily modified to be compatible with its scanning technology. The add-on also implements basic browser intrumentation to simulate a human interaction to trigger some hard to detect DOM-based XSS conditions.
