SecurityTracker URL:  http://securitytracker.com/id/1013907
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Updated:  May 8 2005
Original Entry Date:  May 6 2005
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information, Execution of arbitrary code via network, Modification of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  Exploit Included:  Yes  
Version(s): 2.0.3 and prior versions
Description:   Some input validation vulnerabilities were reported in Invision Power Board in 'login.php' and 'topics.php'. A remote user can inject SQL commands. A remote user can also conduct cross-site scripting attacks.

The 'sources/login.php' script does not properly validate user-supplied input in certain login methods. A remote user can supply a specially crafted URL to execute SQL commands on the underlying database. Magic_quotes_gpc does not need to be 'off' for this vulnerability to be exploited.

The 'sources/topics.php' script does not properly validate user-supplied input in the 'highlite' parameter when displaying search parameters. 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 Invision Power 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.

James Bercegay of the GulfTech Security Research Team reported this vulnerability.

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

A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the Invision Power 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:   The vendor has described a fix at:
