Updated: Jun 8 2008
|
Original Entry Date: Aug 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): 1.0.3(stable), 1.1

Description: A vulnerability was reported in toendaCMS. A remote user can conduct cross-site scripting attacks.
The '/toendaCMS/' scripts do not properly filter HTML code from user-supplied input in the 's' 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 toendaCMS 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 vendor was notified on July 21, 2006.
David Vieira-Kurz discovered this
vulnerability.

Original Advisory:
============
http://www.majorsecurity.de/index_en2.php?major_rls=major_rls27
Introduction
============
"The toendaCMS Content Management and Weblogging tool gives you a modern,
professional publishing system, based on an SQL and/or XML database.." (from Vendor's page)
More Details
============
Input passed directly to the "?s" parameter in "/toendaCMS/" is not properly sani
tised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in a user's browser session in contex
t of an affected site.
It works with a script code like this:
>'><script%20%0a%0d>alert(123456789)%3B</script>
Fix
===
None known.
Solution
=============
Edit the source code to ensure that input is properly sanitised.
You should work with "htmlspecialchars()" or "htmlentities()" php-function to ens
ure that html tags
are not going to be executed. Further it is recommend to set off the "register globals" opt
ion in the
"php.ini" on your webserver.
Example:
<?php
$pass = htmlentities($_POST['pass']);
echo htmlspecialchars("<script");
$id = intval($_POST['id']);
?>
Set "register_globals" to "Off".
