vBulletin contains a flaw that allows a remote cross site scripting (XSS) attack. This flaw exists because the application does not validate the value of two global variables ('$scriptpath' and '$url') which are set based on the referring URL, upon inclusion in multiple scripts. 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.
