Module Overview

Name: VMware Fusion USB Arbitrator Setuid Privilege Escalation
Module: exploit/osx/local/vmware_fusion_lpe
Source code: modules/exploits/osx/local/vmware_fusion_lpe.rb
Disclosure date: 2020-03-17
Last modification time: 2021-08-27 17:15:33 +0000
Supported architecture(s): x86, x64
Supported platform(s): OSX
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2020-3950

This exploits an improper use of setuid binaries within VMware Fusion 10.1.3 - 11.5.3. The Open VMware USB Arbitrator Service can be launched outide of its standard path which allows loading of an attacker controlled binary. By creating a payload in the user home directory in a specific folder, and creating a hard link to the 'Open VMware USB Arbitrator Service' binary, we're able to launch it temporarily to start our payload with an effective UID of 0. @jeffball55 discovered an incomplete patch in 11.5.3 with a TOCTOU race. Successfully tested against 10.1.6, 11.5.1, 11.5.2, and 11.5.3.

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/osx/local/vmware_fusion_lpe
msf exploit(vmware_fusion_lpe) > show targets
    ... a list of targets ...
msf exploit(vmware_fusion_lpe) > set TARGET target-id
msf exploit(vmware_fusion_lpe) > show options
    ... show and set options ...
msf exploit(vmware_fusion_lpe) > set SESSION session-id
msf exploit(vmware_fusion_lpe) > exploit

Required Options

  • SESSION: The session to run this module on.

Knowledge Base

Vulnerable Application

This exploits an improper use of setuid binaries within VMware Fusion 10.1.3 - 11.5.3. The Open VMware USB Arbitrator Service can be launched outide of its standard path which allows loading of an attacker controlled binary. By creating a payload in the user home directory in a specific folder, and creating a hard link to the Open VMware USB Arbitrator Service, we're able to launch it temporarily to start our payload with an effective UID of 0.

Additional description can be found in @mirchr's exploit.

It was found that VMware Fusion 11.5.3, which patched the previous vulnerability utilized an incomplete patch. The patch checked for a correct code signature on the VMware USB Arbitrator Service at start, but not at launch, thus creating a TOCTOU race condition. The discoverer @jeffball55 demoed the exploit working in ~30 attempts. This module has been successful between 5 and 25 attempts.

VMware Fusion 11.5.1 is available from VMware.

Verification Steps

  1. Install the application
  2. Start msfconsole
  3. Get a shell
  4. Do: use exploit/osx/local/vmware_fusion_lpe
  5. Do: set session #
  6. Do: run
  7. You should get a euid=0 shell.

Options

MAXATTEMPTS

The maximum attempts to start VMware USB Arbitrator Service, attempting to win the race against 11.5.3. Default is 75.

Session

Which session to use this exploit on.

  This exploits an improper use of setuid binaries within VMware 
  Fusion 10.1.3 - 11.5.3. The Open VMware USB Arbitrator Service can 
  be launched outide of its standard path which allows loading of an 
  attacker controlled binary. By creating a payload in the user home 
  directory in a specific folder, and creating a hard link to the 
  'Open VMware USB Arbitrator Service' binary, we're able to launch it

  @jeffball55 discovered an incomplete patch in 11.5.3 with a TOCTOU 
  race. Successfully tested against 10.1.6, 11.5.1, 11.5.2, and 
  11.5.3.
