CMS Made Simple Antz Toolkit 1.02 Module Arbitrary File Upload Vulnerability. Webapps exploit for php platform

The Antz toolkit module for CMS Made Simple is prone to a vulnerability that lets attackers upload arbitrary files because the application fails to adequately sanitize user-supplied input.

An attacker can exploit this vulnerability to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible.

Antz toolkit 1.02 is vulnerable; other versions may also be affected.
