WoltLab Burning Board Input Validation Hole in 'thread.php' in 'hilight' Parameter Permits Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1013790
SecurityTracker URL:  http://securitytracker.com/id/1013790
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Apr 23 2005
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 2.3.1 and prior versions
Description:   An input validation vulnerability was reported in WoltLab Burning Board. A remote user can conduct cross-site scripting attacks.

The 'thread.php' script does not properly validate user-supplied input in the 'hilight' parameter. A remote user can create a specially crafted URL that, when loaded 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 WoltLab Burning Board 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 URL is provided:

/thread.php?threadid=[TOPIC_ID]&hilight=[XSS]

deluxe89 discovered this vulnerability.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the WoltLab Burning Board 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.
Solution:   No solution was available at the time of this entry.
