VHCS check_login Authentication Bypass Vulnerability

Vulnerability Assessment Summary
Tries to access a restricted script using VHCS

Detailed Explanation for this Vulnerability Assessment

Summary :

The remote web server contains a PHP application that is prone to an
authentication bypass vulnerability.

Description :

The remote host is running VHCS, a control panel for hosting
providers.

The GUI portion of the version of VHCS installed on the remote host
does not halt script execution if 'check_login()' fails. A possible hacker
can leverage this flaw to bypass authentication and access VHCS
application scripts that would otherwise be restricted.
