CVE-2017-18368 is an unauthenticated command injection vulnerability affecting the ZyXEL P660HN-T1A router running TCLinux firmware version 7.3.15.0 v001 / 3.40(ULM.0)b31 as distributed by TrueOnline. The flaw exists in the Remote System Log forwarding functionality exposed through the ViewLog.asp page. Insufficient sanitization of the remote_host parameter allows attacker-controlled input to be incorporated into system command execution, enabling arbitrary shell command injection without authentication.

This repository contains a single Metasploit module targeting an unauthenticated command injection vulnerability (CVE-2017-18368) in the TrueOnline/ZyXEL P660HN-T v1 router's web interface. The exploit leverages a POST request to the '/cgi-bin/ViewLog.asp' endpoint, injecting a command to start a telnet daemon that provides a root shell to the attacker. The module includes a check method to verify the target device by querying '/cgi-bin/authorize.asp'. The exploit is weaponized, allowing for customizable payloads and integration with the Metasploit framework. The code is written in Ruby and is structured as a standard Metasploit exploit module, with clear separation of initialization, checking, and exploitation logic. No hardcoded IP addresses or external domains are present; the exploit targets the router's local HTTP interface.
