This repository contains a Python exploit script (CVE-2025-39538.py) targeting the WordPress WP-Advanced-Search plugin (versions <= 3.3.9.3) for an authenticated arbitrary file upload vulnerability (CVE-2025-39538). The exploit automates the process of logging into a WordPress site, extracting a required nonce from a plugin admin page, and uploading a simple PHP web shell to the server via a crafted POST request. The uploaded shell allows remote command execution through HTTP requests. The README provides clear usage instructions, details about the vulnerability, and post-exploitation guidance. The repository includes a requirements.txt for dependencies and a standard MIT license. The main attack vector is network-based, requiring valid WordPress credentials. Key endpoints include the WordPress login page, the plugin's import/export admin page, and the admin-post.php upload handler. The exploit is operational, providing a working web shell payload but requiring manual interaction for post-exploitation.
