This repository contains a single Metasploit module targeting TP-Link NCXXX series cloud cameras (models NC200, NC210, NC220, NC230, NC250, NC260, NC450) running Linux. The exploit leverages an authenticated command injection vulnerability (CVE-2020-12109) in the Bonjour system name functionality, allowing arbitrary command execution as root via the /setsysname.fcgi endpoint. The module requires valid web interface credentials and interacts with the device over HTTP(S), first authenticating, then enabling the Bonjour service, and finally injecting the payload using the sysname parameter. For NC210, exploitation requires chaining with CVE-2020-12110. The payload is delivered using Metasploit's CmdStager, typically fetching a MIPSLE binary via wget. The module is weaponized, allowing customizable payloads and reliable exploitation. The code is written in Ruby and structured as a standard Metasploit exploit module.
