Full title: WordPress Backup Migration 1.3.7 Remote Command Execution Exploit 
Category: web applications
Platform: php
This Metasploit module exploits an unauthenticated remote command execution vulnerability in WordPress Backup Migration plugin versions 1.3.7 and below. The vulnerability is exploitable through the Content-Dir header which is sent to the /wp-content/plugins/backup-backup/includes/backup-heart.php endpoint. The exploit makes use of a neat technique called PHP Filter Chaining which allows an attacker to prepend bytes to a string by continuously chaining character encoding conversions. This allows an attacker to prepend a PHP payload to a string which gets evaluated by a require statement, which results in command execution.
