Grandstream GXV3175 'settimezone' Unauthenticated Command Execution

Description

This module exploits a command injection vulnerability in Grandstream GXV3175 IP multimedia phones. The 'settimezone' action does not validate input in the 'timezone' parameter allowing injection of arbitrary commands. A buffer overflow in the 'phonecookie' cookie parsing allows authentication to be bypassed by providing an alphanumeric cookie 93 characters in length. This module was tested successfully on Grandstream GXV3175v2 hardware revision V2.6A with firmware version 1.0.1.19.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
