Loading vulnerability…
Grandstream UCM6200 series firmware versions 1.0.20.22 and below store user passwords in cleartext within an SQLite database. This insecure storage mechanism allows any attacker with access to the database file to retrieve all user passwords, potentially leading to unauthorized access and privilege escalation.

This repository contains a single Metasploit auxiliary module targeting Grandstream UCM62xx IP PBX devices vulnerable to a blind SQL injection (CVE-2020-5724) and cleartext password storage (CVE-2020-5723). The exploit operates by sending crafted WebSocket requests to the '/websockify' endpoint, leveraging a blind SQL injection vulnerability in the authentication challenge mechanism. It uses the server's response status to infer database contents and extracts usernames and cleartext passwords from the 'users' table. The module also checks the device's firmware version via the '/cgi' endpoint to determine if it is vulnerable (versions below 1.0.20.22). The exploit is operational, providing credential extraction capabilities, and is implemented in Ruby as part of the Metasploit framework.
