CVE-2020-5722 is an unauthenticated SQL injection vulnerability in the HTTP interface of Grandstream UCM6200 series devices. A remote attacker can send a crafted HTTP request to inject SQL statements without authentication. On affected versions prior to 1.0.19.20, the flaw can be leveraged to achieve shell command execution as root, indicating that the SQL injection can be chained into operating-system command execution through backend application logic. On versions prior to 1.0.20.17, the vulnerability can also be used to inject HTML content into password recovery emails. The issue affects internet-exposed UCM6200 appliances through their web management interface and has been observed in botnet exploitation activity because it is remotely reachable and does not require credentials.

This repository contains a single Metasploit module targeting Grandstream UCM62xx IP PBX devices (firmware <1.0.19.20) via an unauthenticated remote code execution vulnerability. The exploit leverages a two-stage attack: first, an SQL injection in the 'Forgot Password' feature, and second, a command injection in a Python script invoked by the device. The module sends crafted POST requests to the '/cgi' endpoint to trigger the vulnerability, allowing arbitrary command execution as root. The payload can be a reverse shell (e.g., netcat) or a dropper, and the exploit is operational, providing real-world attack capability. The code is written in Ruby and is structured as a standard Metasploit module, with clear separation of version checking, exploitation, and payload delivery logic. No extraneous files are present; the repository is focused solely on this exploit.
