Elementor Pro for WordPress up to version 3.11.6 contains a vulnerability in the update_page_option function, where a missing capability check allows authenticated users with only subscriber-level permissions to update arbitrary site options. This can be exploited to escalate privileges or modify site configuration.

This repository contains a Python proof-of-concept exploit for CVE-2023-3124, targeting the Elementor Pro plugin for WordPress (versions <= 3.11.6). The exploit leverages a missing capability check in the 'update_page_option' function, allowing an authenticated user with subscriber privileges to escalate their privileges to administrator. The main script, 'PoC.py', performs the following steps: logs in to the target WordPress site as a subscriber, extracts a required nonce from the response, and sends crafted POST requests to the '/wp-admin/admin-ajax.php' endpoint to set 'users_can_register' to true and change the 'default_role' to 'administrator'. This results in new users being created with administrator privileges. The repository also includes a README.md with a description of the vulnerability and a requirements.txt listing dependencies (bs4, requests, argparse). The exploit is network-based and requires valid subscriber credentials to execute.
