DeluxeBB Input Validation Bug in 'limit' Parameter Permits SQL Injection and Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1014924
SecurityTracker URL:  http://securitytracker.com/id/1014924
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Sep 16 2005
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information, User access via network
Exploit Included:  Yes  

Description:   LINUX from sosvulnerable.net reported a vulnerability in DeluxeBB. A remote user can inject SQL commands and conduct cross-site scripting attacks.

The script does not properly filter HTML code from user-supplied input in the 'limit' parameter before displaying the input. 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 DeluxeBB 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:

http://[target]/community/index.php?limit=<script>alert('LINUX%20aka');</script>

A remote user can also supply a specially crafted parameter value to execute SQL commands on the underlying database.

A demonstration exploit URL is provided:

http://[target]/community/index.php?limit='LINUX

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the DeluxeBB 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.

A remote user can execute SQL commands on the underlying database.

Solution:   No solution was available at the time of this entry.
