[Full-disclosure] Element CMS script insertion vulnerability

Date: Fri Jul 13 2007 - 20:41:29 CDT

TeamIntell Security Advisory TISA2007-06-Public
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)


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

Proof of Concept:



Vendor informed. Official patch not available.

Note: because of arrogant and unprofessional vendor's
response TeamIntell decided to release the advisory.
