"The remote server runs a version of CjOverkill, a free traffic trading 
script that is as old as or older than version 4.0.3.

The remote version of this software is affected by a cross-site 
scripting vulnerability in the script 'trade.php'. This issue is due 
to a failure of the application to properly sanitize user-supplied 
input.

As a result of this vulnerability, it is possible for a remote 
attacker to create a malicious link containing script code that will
be executed in the browser of an unsuspecting user when followed. 

This may facilitate the theft of cookie-based authentication 
credentials as well as other attacks.");
