The remote server runs a version of CjOverkill, a free traffic trading script which 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.

Upgrade to version 4.0.4 or newer.
