The remote host is running vBulletin, a web based bulletin board system written in PHP. The remote version of this software is vulnerable to a cross-site scripting issue, due to a failure of the application to properly sanitize user-supplied URI 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 vBulletin 3.0.2 or newer
