Loading vulnerability…
A command injection vulnerability exists in the Ctek SkyRouter 4200 and 4300 devices, specifically in the apps/a3/cfg_ethping.cgi script. Remote attackers can execute arbitrary commands on the device by supplying shell metacharacters in the PINGADDRESS parameter when performing a 'u' action. This allows attackers to inject and execute shell commands with the privileges of the web server process.

This repository contains a single Metasploit module (modules/exploits/unix/http/ctek_skyrouter.rb) targeting CTEK SkyRouter 4200 and 4300 devices. The exploit leverages an unauthenticated command injection vulnerability (CVE-2011-5010) in the /apps/a3/cfg_ethping.cgi HTTP endpoint. By sending a specially crafted POST request with a malicious PINGADDRESS parameter, the attacker can execute arbitrary commands as root on the target device. The module supports generic command payloads and is operational, allowing for remote code execution. The code is written in Ruby and is structured as a standard Metasploit exploit module, making it easy to use within the Metasploit framework.
