'Description' => %q{
This module exploits a stack-based buffer overflow vulnerability in
version 5.3.11.1230 of scadaTEC's ScadaPhone.
2013-08-30 21:28:54 +00:00
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.
