Loading vulnerability…
The Backup Guard WordPress plugin before version 1.6.0 fails to validate that imported files are of the expected SGBP format and extension. This allows high privilege users (admin and above) to upload arbitrary files, including executable PHP files, which can then be executed on the server, resulting in remote code execution (RCE).

This repository contains a single Metasploit module targeting an authenticated remote code execution vulnerability (CVE-2021-24155) in the Wordpress Backup Guard plugin versions prior to 1.6.0. The exploit requires valid Wordpress admin credentials and leverages an arbitrary file upload flaw to upload a PHP payload (such as a reverse shell) to the server. The payload is then triggered by accessing it via the web, resulting in code execution as the web server user. The module is fully integrated with Metasploit, allowing for customizable payloads and automated cleanup. The main file is written in Ruby and follows standard Metasploit module conventions, with clear separation of authentication, token retrieval, file upload, and payload execution steps. Key endpoints involved include the Wordpress admin-ajax.php for file upload and the uploads directory for payload execution.
This repository contains a Metasploit module (CVE-2021-24155.rb) that exploits an authenticated arbitrary file upload vulnerability in the WordPress Backup Guard plugin (versions prior to 1.6.0). The exploit requires valid admin credentials for a WordPress site. It works by logging in, retrieving a CSRF token, and uploading a PHP payload (such as a reverse shell) via the vulnerable plugin's AJAX endpoint. The payload is then executed by accessing it through the web server, granting remote code execution. The module uses standard Metasploit mixins for HTTP, WordPress, and command staging. The README provides a brief description of the exploit and its requirements. No hardcoded IPs or domains are present; all endpoints are relative to the target WordPress installation.
