CVE-2017-6334 is a command injection vulnerability in dnslookup.cgi on NETGEAR DGN2200 devices running firmware through 10.0.0.50. The flaw allows a remote authenticated user to supply shell metacharacters in the host_name parameter of an HTTP POST request, causing attacker-controlled input to be incorporated into an operating system command without proper neutralization. Successful exploitation results in arbitrary OS command execution on the affected device. This issue is distinct from CVE-2017-6077.

This repository contains a single Metasploit module (modules/exploits/linux/http/netgear_dnslookup_cmd_exec.rb) that exploits a command injection vulnerability (CVE-2017-6334) in NETGEAR DGN2200v1/v2/v3/v4 routers. The exploit works by sending a specially crafted POST request to the /dnslookup.cgi endpoint, authenticating with valid credentials, and injecting arbitrary shell commands via the 'host_name' parameter. The module includes a check method to verify if the target is a vulnerable NETGEAR router by inspecting the WWW-Authenticate header. The exploit is weaponized, allowing the attacker to execute arbitrary shell commands on the device. The only required configuration is the router's IP, port (default 80), and valid credentials. The code is written in Ruby and is designed to be used within the Metasploit framework.
