|
|
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.
