Description

This module exploits an authenticated RCE in Cayin CMS in the system_service.cgi file's ntpIp Parameter. The field is limited in size, so
repeated requests are made to achieve a larger payload.
Cayin CMS-SE is built for Ubuntu 16.04 (20.04 failed to install correctly), so the
environment should be pretty set and not dynamic between targets.
Results in root level access.
