Description

This module exploits a command injection in TimeMachine on macOS order to run a payload as root. The tmdiagnose binary on OSX from a command injection vulnerability that can be exploited by creating a
specially crafted disk label.

The tmdiagnose binary uses awk to list every mounted volume, and composes
shell commands based on the volume labels. By creating a volume label with the
backtick character, we can have our own binary executed with root priviledges.
