AI-analyzed exploit summary This repository contains functional exploit code demonstrating OS command injection (CWE-78) in Pi-hole AdminLTE v5.21 via the `webtheme` parameter in `savesettings.php`. Multiple PoC scripts are provided, including semicolon, command substitution, and pipe-based injection techniques.

Pi-hole Admin Interface is a web interface for managing Pi-hole, a network-level ad and internet tracker blocking application. Versions prior to 6.0 have a critical OS Command Injection vulnerability in the savesettings.php file. The application takes the user-controlled $_POST['webtheme'] parameter and concatenates it directly into a system command executed via PHP's exec() function. Since the input is neither sanitized nor validated before being passed to the shell, an attacker can append arbitrary system commands to the intended pihole command. Furthermore, because the command is executed with sudo privileges, the injected commands will run with elevated (likely root) privileges. Version 6.0 patches the issue.
