What it detects

This rule detects the OMI server or engine process spawning a shell or command interpreter, which the OMIGOD CVE-2021-38647 and CVE-2021-38648 flaws abuse to execute attacker commands as root through the SCX provider on Azure Linux virtual machines. Such child processes indicate unauthenticated remote code execution or local privilege escalation and should be investigated as an active intrusion.
