`Advisory: ActiveWeb Contentserver CMS Multiple Cross Site Scriptings   
  
RedTeam Pentesting discovered three Cross Site Scripting  
vulnerabilities in the activeWeb contentserver CMS during a penetration  
test. One of the Cross Site Scriptings is persistent.  
  
  
Details  
=======  
  
Product: activeWeb contentserver  
Affected Versions: <= 5.6.2929  
Fixed Versions: 5.6.2964  
Vulnerability Type: Cross Site Scripting  
Security-Risk: high  
Vendor-URL: http://www.active-web.de/aw/home/Produkte/~gf/contentserver/  
Vendor-Status: informed, fixed version released  
Advisory-URL: http://www.redteam-pentesting.de/advisories/rt-sa-2007-005.php  
Advisory-Status: public  
CVE: CVE-2007-3014  
CVE-URL: http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2007-3014  
  
  
Introduction  
============  
  
contentserver is the comprehensive, scalable Content Management System  
for professional requirements. It combines editorial system, website  
management and development platform for web applications in one package.  
  
(translation of the description on the vendor's homepage)  
  
  
XSS Error Page rights.asp  
=========================  
  
The variable "msg" of the ASP script "rights.asp" is not properly  
filtered.  
  
Proof of Concept  
----------------  
  
http://www.example.com/errors/rights.asp  
?awReadAccessRight=True  
&msg=<script>alert('XSS')</script>  
  
  
XSS Error Page transaction.asp  
==============================  
  
The variable "msg" of the ASP script "transaction.asp" is not properly  
filtered.  
  
Proof of Concept  
----------------  
  
http://www.example.com/errors/transaction.asp  
?msg=<script>alert('XSS')</script>  
  
  
Persistent XSS Mimetypes  
========================  
  
As editors, users can add new mimetypes to the the system. The name of  
the new mimetype can contain arbitrary code. This allows for a  
persistent Cross Site Scripting.  
  
Proof of Concept  
----------------  
  
As an editor, log into the management interface and add a new mimetype.  
For the name, use a script, e.g.  
  
<script>alert('XSS')</script>  
  
Everytime a user looks at the mimetypes, the code will be executed.  
  
  
Workaround  
==========  
  
A possible workaround would be to use a filtering application set up in  
front of the real webserver, mitigating the risk of being exploited.  
  
  
Fix  
===  
  
The vulnerability is fixed in release 5.6.2964.  
  
  
Security Risk  
=============  
  
The risk is high, as these XSS can be used e.g. to steal session cookies  
of logged-in users.
