CVE-2019-17621 is a command execution vulnerability in the D-Link DIR-859 Wi-Fi router (firmware versions 1.05 and 1.06B01 Beta01). The vulnerability resides in the UPnP endpoint /gena.cgi, which allows an unauthenticated remote attacker on the local network to execute arbitrary system commands as root by sending a specially crafted HTTP SUBSCRIBE request to the UPnP service.

This repository contains a single Metasploit module targeting D-Link DIR-859 routers vulnerable to unauthenticated remote command execution via the UPnP interface (CVE-2019-17621). The exploit leverages a command injection vulnerability in the /gena.cgi endpoint, accessible without authentication on the router's web interface (typically port 49152). The module uses Metasploit's command stager to deliver a payload (default: linux/mipsbe/meterpreter_reverse_tcp) using either wget or echo, resulting in a reverse shell or Meterpreter session on the target device. The exploit is fully weaponized, supporting automated payload delivery and session management. The only file present is a Ruby script structured as a standard Metasploit exploit module, making use of the HttpClient and CmdStager mixins for network communication and payload delivery.
