Description: x1ng reported a vulnerability in CMS Made Simple. A remote user can conduct cross-site scripting attacks.
The script does not properly filter HTML code from user-supplied input in the 'page' 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 CMS Made Simple 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]/[cms]/index.php?page=<script>alert(document.cookie);</script>
|
Impact: A remote user can access the target user's cookies (including authentication cookies), if any, associated with the site running the
CMS Made Simple 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.
