Description

The remote version of vBulletin 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.
