Loading vulnerability…
ZyXEL P660HN-T1A v2 routers distributed by TrueOnline contain three user accounts with default passwords, including two hardcoded service accounts: 'true:true' and 'supervisor:zyad1234'. These accounts can be used to authenticate to the web interface, enabling attackers to exploit further vulnerabilities such as authenticated command injection and to modify router settings.

This repository contains a single Metasploit module targeting the TrueOnline/ZyXEL P660HN-T v2 router. The exploit leverages an authenticated command injection vulnerability in the router's remote log forwarding page, accessible via the web interface. The attacker must authenticate (default credentials: supervisor/zyad1234) and then injects a shell script into the device using a vulnerable POST parameter. The script downloads a MIPSBE ELF payload from the attacker's TFTP server and executes it, providing a reverse shell or arbitrary code execution. The module is operational, supports custom payloads, and is designed for use within the Metasploit framework. The main endpoints involved are the authentication page, the vulnerable log settings page, and a static JS file used for device fingerprinting. The exploit is relevant for CVE-2017-18370 and CVE-2017-18371.
