CVE-2025-12539 affects the TNC Toolbox: Web Performance plugin for WordPress in all versions up to and including 1.4.2. The vulnerability is caused by the plugin's "Tnc_Wp_Toolbox_Settings::save_settings" function storing cPanel API credentials—including hostname, username, and API key—in files under the web-accessible wp-content directory without adequate access protection. Because these files are reachable from the web, an unauthenticated attacker can retrieve the stored credentials. Exposure of valid cPanel API credentials can then be leveraged to interact directly with the cPanel API, enabling follow-on actions such as arbitrary file upload and remote code execution, potentially resulting in full compromise of the affected hosting environment.

This repository contains a Python exploit script (CVE-2025-12539.py) targeting the TNC Toolbox: Web Performance WordPress plugin (versions <= 1.4.2). The exploit leverages an unauthenticated sensitive information exposure vulnerability, where the plugin stores cPanel credentials in web-accessible files without proper access controls. The script first checks the plugin version by fetching the readme.txt file, then, if vulnerable, attempts to retrieve the cPanel username, API key, and server hostname from specific configuration files. The output is a structured JSON report containing the extracted credentials and vulnerability status. The repository also includes a README with detailed usage instructions, a requirements.txt specifying the 'requests' library, and a license file. The exploit is operational, providing real credential extraction if the target is vulnerable, and is not a mere detection script.
