CVE-2022-31137 is a remote code execution vulnerability in Roxy-WI, a web interface used to manage HAProxy, Nginx, Apache, and Keepalived servers. Versions prior to 6.1.1.0 are affected. The flaw is caused by improper neutralization of user-supplied input before it is passed to system command execution in the subprocess_execute function in /app/options.py. Because the application does not adequately process or sanitize attacker-controlled input, an unauthenticated remote attacker can trigger execution of arbitrary system commands via the web interface.

This repository contains a single Metasploit module (modules/exploits/linux/http/roxy_wi_exec.rb) that exploits an unauthenticated command injection vulnerability (CVE-2022-31137) in Roxy-WI prior to version 6.1.1.0. The exploit targets the '/app/options.py' endpoint, sending a crafted POST request with a malicious 'ipbackend' parameter to achieve remote code execution as the web server user. The module supports both in-memory command execution and staged payload delivery (dropper) for Unix/Linux targets. The exploit is weaponized, allowing for customizable payloads via the Metasploit framework. The repository is structured as a typical Metasploit exploit module, with all logic contained in a single Ruby file. No hardcoded IPs or external domains are present; the only fingerprintable endpoint is the vulnerable URI. The exploit does not require authentication and is effective against default installations of vulnerable Roxy-WI versions.
