Vulnerability Details : CVE-2018-20735

** DISPUTED ** An issue was discovered in BMC PATROL Agent through 11.3.01. It was found that the PatrolCli application can allow for lateral movement and escalation of privilege inside a Windows Active Directory environment. It was found that by default the PatrolCli / PATROL Agent application only verifies if the password provided for the given username is correct; it does not verify the permissions of the user on the network. This means if you have PATROL Agent installed on a high value target (domain controller), you can use a low privileged domain user to authenticate with PatrolCli and then connect to the domain controller and run commands as SYSTEM. This means any user on a domain can escalate to domain admin through PATROL Agent. NOTE: the vendor disputes this because they believe it is adequate to prevent this escalation by means of a custom, non-default configuration.

- Metasploit Modules Related To CVE-2018-20735

BMC Patrol Agent Privilege Escalation Cmd Execution
This module leverages the remote command execution feature provided by the BMC Patrol Agent software. It can also be used to escalate privileges on Windows hosts as the software runs as SYSTEM but only verfies that the password of the provided user is correct. This also means if the software is running on a domain controller, it can be used to escalate from a normal domain user to domain admin as SYSTEM on a DC is DA. **WARNING** The windows version of this exploit uses powershell to execute the payload. The powershell version tends to timeout on the first run so it may take multiple tries.
