Cayin CMS NTP Server RCE
Description
This module exploits an authenticated RCE in Cayin CMS <= 11.0. The RCE is executed 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.

- Collect and share all the information you need to conduct a successful and efficient penetration test
- Simulate complex attacks against your systems and users
- Test your defenses to make sure they’re ready
- Automate Every Step of Your Penetration Test
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.
