'Name' => 'ScadaTEC ScadaPhone <= v5.3.11.1230 Stack Buffer Overflow',

'Description'=> %q{

This module exploits a stack-based buffer overflow vulnerability in

version 5.3.11.1230 of scadaTEC's ScadaPhone.

In order for the command to be executed, an attacker must convince someone to

load a specially crafted project zip file with ScadaPhone.

By doing so, an attacker can execute arbitrary code as the victim user.
