Description:
David 'Aesthetico' Vieira-Kurz of MajorSecurity reported a vulnerability in ZMS. A remote user can conduct cross-site scripting attacks.
The searchform does not properly filter HTML code from user-supplied input 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 ZMS 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.

Original Advisory:
----------------------------
http://www.majorsecurity.de/advisory/major_rls12.txt
Affected Products:
----------------------------
ZMS 2.9 and prior
Description:
----------------------------
ZMS is a ZOPE-based content management system for science, technology and medicine.
Requirements:
----------------------------
register_globals = On
Vulnerability:
----------------------------
Input passed to the searchform input fields is not properly sanitised before being returned to the user.
This can be exploited to execute arbitrary HTML and script code in context of an affected site.
Solution:
----------------------------
Edit the source code to ensure that input is properly sanitised.
You should work with "htmlspecialchars()" or "strip_tags()" php-function to ensure that html tags
are not going to be executed.
Example:
<?php
echo htmlspecialchars("<script");
?>
Set "register_globals" to "Off".
Exploitation:
---------------------------
Goto the searchform input fields and type in following line as searchword:
<script>alert("MajorSecurity")</script>
