Loading vulnerability…
CVE-2024-28247 is a vulnerability in Pi-hole, a DNS sinkhole platform, that allows an authenticated user to read arbitrary internal server files. The vulnerability is triggered when updating adlists from a local file (using a URL beginning with 'file*'). If the specified file contains non-domain lines, up to five of these lines are printed to the screen, potentially exposing sensitive file contents. The application runs with elevated privileges, increasing the risk of sensitive data exposure.

This repository provides a working exploit for CVE-2024-28247, a vulnerability in Pi-hole (<=5.17.3) that allows authenticated users to read arbitrary files on the server via the web admin interface. The exploit is implemented in Python (exploit.py) and requires the attacker to know the admin password for the Pi-hole instance. The script performs the following steps: logs into the admin interface, extracts a CSRF token, injects a file:// URI (such as file:///etc/shadow) as an adlist, and then retrieves the contents of the file via a subsequent request. The repository includes a README.md with usage instructions and a requirements.txt listing dependencies (requests, beautifulsoup4, urllib3). The main entry point is exploit.py. The exploit targets the Pi-hole web interface and leverages several HTTP endpoints to perform the attack. The exploit is operational and demonstrates the ability to read sensitive files from the target system.
