"According to its banner, the remote version of vBulletin is vulnerable
to a cross-site scripting issue, due to a failure of the application

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
