Windows Update Orchestrator unchecked ScheduleWork call - Metasploit


This page contains detailed information about how to use the exploit/windows/local/cve_2020_1313_system_orchestrator metasploit module. For list of all metasploit modules, visit the Metasploit Module Library.

Module Overview


Name: Windows Update Orchestrator unchecked ScheduleWork call
Module: exploit/windows/local/cve_2020_1313_system_orchestrator
Source code: modules/exploits/windows/local/cve_2020_1313_system_orchestrator.rb
Disclosure date: 2019-11-04
Last modification time: 2021-09-08 21:56:02 +0000
Supported architecture(s): -
Supported platform(s): Windows
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2020-1313

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 Ranking and Traits


Module Ranking:

  • excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.

Basic Usage


Note: To run a local exploit, make sure you are at the msf prompt. Also, to check the session ID, use the sessions command.

msf > use exploit/windows/local/cve_2020_1313_system_orchestrator
msf exploit(cve_2020_1313_system_orchestrator) > show targets
    ... a list of 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) > set SESSION session-id
msf exploit(cve_2020_1313_system_orchestrator) > exploit

Required Options


  • SESSION: The session to run this module on.

Knowledge Base


Vulnerable Application


Windows 10 and Server x64 build versions above 17763 to 19041.

Introduction

This module abuses CVE-2020-1313, a unchecked API call that allows a regular user to schedule a job that will run as system. The API call, ScheduleWork, will create a task in the System Update Orchestrator automatically scheduled to run at a time when the system is expected to be idle. The user cannot request or affect the scheduled time of execution. The scheduled job data is stored in HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\WindowsUpdate\\Orchestrator\\UScheduler\\x Where x is a numeric key assigned to the job.

Verification Steps


  1. Start msfconsole
  2. use exploit/multi/handler
  3. set payload <payload>
  4. set [r|l]host
  5. run (leave running)
  6. Start msfconsole
  7. use windows/local/cve_2020_1313_system_orchestrator
  8. set session <session>
  9. set payload <payload_matching_above>
  10. set verbose true
  11. Verify The job is scheduled
  12. Leave everything running
  13. Go to bed
  14. Have a healthy Breakfast, maybe some coffee if you want
  15. verify you got a callback as SYSTEM

Options


EXECUTE_DELAY The number of seconds to sleep after uploading the exploit and launching it.

EXPLOIT_NAME The name of the exploit EXE as it will appear on target

EXPLOIT_TIMEOUT The maximum time to wait for a response from the exploit binary.

PAYLOAD_NAME The name of the payload EXE as it will appear on target

WRITABLE_DIR Directory to use for file upload and linking; this should not already exist. This directory will require manual cleanup.
