TrixBox CE endpoint_devicemap.php Authenticated Command Execution

This module exploits an authenticated OS command injection
vulnerability found in Trixbox CE version 1.2.0 to 2.8.0.4
inclusive in the "network" POST parameter of the
"/maint/modules/endpointcfg/endpoint_devicemap.php" page.
Successful exploitation allows for arbitrary command execution
on the underlying operating system as the "asterisk" user.
Users can easily elevate their privileges to the "root" user
however by executing "sudo nmap --interactive" followed by "!sh"
from within nmap.
