Element CMS "s" parameter script insertion vulnerability  
=========================================================================  
  
  
Release Date: 14.7.2007  
Severity: Less critical  
Impact: Cross-site scripting (XSS)  
Status: Official patch not available (0-day)  
Software: Element CMS  
Vendor: http://www.element.si

Disclosed: Edi Strosar (TeamIntell)  
  
  
Description:  
============  
  
Element CMS, a full featured Slovenian content management   
system, is prone to a cross-site scripting vulnerability   
because the application fails to properly sanitize   
user-supplied input.  
  
Input passed to the "s" parameter in default.asp is not   
properly sanitized before being used. This can be   
exploited to insert arbitrary HTML and script code in a   
user's browser session in context of an affected site.  
  
The vulnerability is reported in all versions of Element   
CMS.

Solution:  
=========  
  
Vendor informed. Official patch not available.  
  
Note: because of arrogant and unprofessional vendor's   
response TeamIntell decided to release the advisory.
