Land Down Under Input Validation Hole in Signature Lets Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1014813
SecurityTracker URL:  http://securitytracker.com/id/1014813
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Aug 29 2005
Impact:   Disclosure of authentication information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Exploit Included:  Yes  

Description:   A vulnerability was reported in Land Down Under. A remote user can conduct cross-site scripting attacks.

The software does not properly filter HTML code from user-supplied input in the user signature before displaying the input. A remote user can create a specially crafted signature and submit a message to the forum. Then, when a target user views the message, arbitrary scripting code will be executed by the target user's browser. The code will originate from the site running the Land Down Under 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.
