Description

This module exploits an authenticated PHP code injection
vulnerability found in openmediavault versions before 4.1.36
and 5.x versions before 5.5.12 inclusive in the "sortfield"
POST parameter of the rpc.php page, because "json_encode_safe()"
is not used in config/databasebackend.inc.
Successful exploitation grants attackers the ability to execute
arbitrary commands on the underlying operating system as root.
