[MajorSecurity Advisory #29]foresite CMS - Cross Site Scripting Issue

Details
=======
Product: ForeSite CMS
Security-Risk: moderated
Remote-Exploit: yes
Vendor-URL: http://www.foresite.ch
Vendor-Status: informed

Credits

Discovered by: David Vieira-Kurz

Original Advisory:
============
http://www.majorsecurity.de/index_2.php?major_rls=major_rls29

Introduction
============
foresite CMS is a content management system.

More Details
============
XSS:
Input passed directly to the "query" parameter in "search_de.html" is not properly sanitised before being returned to 
the user.
This can be exploited to execute arbitrary HTML and script code in a user's browser session in context of an affected 
site.

Fix
===
None

Solution
=============
Edit the source code to ensure that input is properly sanitised.
You should work with "htmlspecialchars()" or "htmlentities()" php-function to ensure that html tags
are not going to be executed. Further it is recommend to set off the "register globals" option in the
"php.ini" on your webserver.

Example:
$pass = htmlentities($_POST['pass']);
$test = htmlspecialchars($_GET('test'));
$id = intval($_POST['id']);
?>
