Description

This module exploits an unauthenticated command injection vulnerability in /controller/ping.php. The S100 through S350 (End of Life) models should be vulnerable to unauthenticated exploitation due to a session handling vulnerability. Later models require authentication which is not provided in this module because we can't test it. The command injection vulnerability is patched in the S650 v2.2 (CVE-2022-40022). Run 'check' first to determine if vulnerable. The server limits outbound ports. Ports 25 and 80 TCP were successfully used for SRVPORT and LPORT while testing this module.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
