2)Vulnerability Description
FlexCMS 3.2.1 suffers from multiple CSRF vulnerabilities which could allow an attacker to change any parameters when an authenticated user/admin
browses a special crafted web page. In this Advisory I've only demonstrate how to change settings of user "demo" (is default user of demo page)
and also I've created a new web page.
