tag_summary = "The remote host is running vBulletin, a web based bulletin board system 
written in PHP.

The remote version of this software seems to be prior or equal to version 2.2.9.
These versions are 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.";

tag_solution = "Upgrade to latest version";
