Description

This module allows an attacker with a privileged Wordpress account to launch a reverse shell
due to an arbitrary file upload vulnerability in Wordpress plugin Backup Guard
This is due to an incorrect check of the uploaded file extension which should be of SGBP type.
Then, the uploaded payload can be triggered by a call to `/wp-content/uploads/backup-guard/.php`
