Exploiting reflected XSS vulnerabilities
Ever since Adobe patched Flash player to stop attackers spoofing certain headers such as Referer, User-Agent, etc, it has been considered impossible to exploit XSS vulnerabilities where the user input is taken from a request header, e.g. when a website prints out what User-Agent a user's browser is sending, without escaping it. With the exception of the Referer header which we can control enough to exploit XSS attacks through it.
I want to showcase several ways in which we can still exploit these vulnerabilities.
