Loading vulnerability…
A buffer overflow vulnerability exists in the NETGEAR WNR2000v5 router in the hidden_lang_avi parameter when invoking the /apply.cgi?/lang_check.html URL. An unauthenticated attacker can exploit this flaw to achieve remote code execution on the device. The vulnerability is present in the router's web management interface and is accessible if remote management is enabled or if the attacker has internal network access.

This repository contains a single Metasploit module targeting a stack buffer overflow vulnerability (CVE-2016-10174) in the NETGEAR WNR2000v5 router's hidden_lang_avi parameter. The exploit can be performed in both authenticated and unauthenticated modes. In authenticated mode, valid web interface credentials are used to quickly retrieve a required timestamp; in unauthenticated mode, the exploit brute-forces the timestamp, which may take significant time. The module is written in Ruby and leverages Metasploit's HTTP client mixin to interact with the router's web interface, and attempts to gain a privileged command shell via telnet (port 23) upon successful exploitation. The exploit is operational and provides a working shell payload. The code is well-structured, with clear separation of functions for checking the target, retrieving timestamps, and performing the exploit. The only endpoints referenced are the router's web interface (HTTP, port 80) and telnet (port 23).
