vBulletin contains a flaw that allows a remote cross site scripting (XSS) attack. This flaw exists because the application does not validate input passed via the URI upon submission to the 'newthread.php' script. This may allow a user to create a specially crafted URL that would execute arbitrary script code in a user's browser within the trust relationship between their browser and the server.
