CVE-2021-33551 is a command injection vulnerability affecting multiple camera devices manufactured by UDP Technology, Geutebrück, and other vendors. The vulnerability allows an attacker to inject and execute arbitrary commands on the underlying operating system of the device remotely. This is due to insufficient input validation in the device firmware, which processes user-supplied data in a way that allows shell metacharacters to be interpreted as commands. The affected devices are widely deployed in critical infrastructure sectors and use third-party firmware from UDP Technology.

This repository contains a single Metasploit module (Ruby) that exploits multiple command injection vulnerabilities in Geutebruck network video devices (G-Cam EEC-2xxx, G-Code EBC-21xx, EFD-22xx, ETHC-22xx, EWPC-22xx) running specific vulnerable firmware versions. The module targets several CGI scripts exposed under the /uapi-cgi/ path, each vulnerable to command injection via different parameters. The exploit works by sending crafted HTTP GET requests to these endpoints, injecting arbitrary commands that are executed as root. The module leverages Metasploit's CmdStager to deliver payloads, typically resulting in a root shell on the device. The module also includes a check method to verify if the target is running a vulnerable firmware version by querying /brand.xml. The exploit is weaponized, allowing for customizable payloads and reliable exploitation. All endpoints are HTTP-based and require network access to the device's web interface.
