Description:
An input validation vulnerability was reported in Jebuch. A remote user can conduct cross-site scripting attacks.
PuWu reported that Jebuch does not filter scripting code from BBCode tags. A remote user can submit a specially crafted comment that, when viewed by a target user, will cause arbitrary scripting code to be executed by the target user's browser. The code will originate from the site running the Jebuch software and will run in the security context of that site. As a result, the code will be able to access the target user's cookies (including authentication cookies), if any, associated with the site, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
A demonstration exploit tag is provided:
[img]"?" onError="window.location='http://dangerousrage.net'"[/img]
The 'eintragen.php3' script is reportedly affected.

Impact:
A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Jebuch software, access data recently submitted by the target user via web form to the site, or take actions on the site acting as the target user.
