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 Modern Events Calendar
This is due to an incorrect check of the uploaded file extension.
Indeed, by using `text/csv` content-type in a request, it is possible to upload a .php payload as is is not forbidden by the plugin.
Finally, the uploaded payload can be triggered by a call to `/wp-content/uploads/.php`
