AI-analyzed exploit summary This repository contains a functional Python exploit for CVE-2023-6972, an unauthenticated arbitrary file deletion vulnerability in the WordPress Backup Migration plugin (<=1.3.9). The exploit automates both vulnerability checking and exploitation, allowing deletion of arbitrary files via a crafted request to the vulnerable endpoint.

Description

The Backup Migration plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 1.3.9 via the 'content-backups' and 'content-name', 'content-manifest', or 'content-bmitmp' and 'content-identy' HTTP headers. This makes it possible for unauthenticated attackers to delete arbitrary files, including the wp-config.php file, which can make site takeover and remote code execution possible.
