Pligg Suffers from a Reflective Cross Site Scripting vulnerability in index.php. For the $_GET['category'] variable.
Exploit code was written that uses this flaw to bypass the CSRF protection to then vote on any pligg article of the
attackers choosing. I took inspiration from the Myspace Sammy worm utilizing XMLHttpRequest() to read the randomly
generated token protection requests from forgery. This is a more serious attack when combined with my Captcha
Implementation Bypass (http://www.rooksecurity.com/blog/?p=17) which allows an attacker to create new user accounts.
