GOG GalaxyClientService Privilege Escalation - Metasploit
This page contains detailed information about how to use the exploit/windows/local/gog_galaxyclientservice_privesc metasploit module. For list of all metasploit modules, visit the Metasploit Module Library.
Module Overview
Name: GOG GalaxyClientService Privilege Escalation
Module: exploit/windows/local/gog_galaxyclientservice_privesc
Source code: modules/exploits/windows/local/gog_galaxyclientservice_privesc.rb
Disclosure date: 2020-04-28
Last modification time: 2021-09-08 21:56:02 +0000
Supported architecture(s): x86, x64
Supported platform(s): Windows
Target service / protocol: -
Target network port(s): -
List of CVEs: CVE-2020-7352
This module will send arbitrary file_paths to the GOG GalaxyClientService, which will be executed with SYSTEM privileges (verified on GOG Galaxy Client v1.2.62 and v2.0.12; prior versions are also likely affected).
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.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
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/gog_galaxyclientservice_privesc
msf exploit(gog_galaxyclientservice_privesc) > show targets
... a list of targets ...
msf exploit(gog_galaxyclientservice_privesc) > set TARGET target-id

... show and set options ...
msf exploit(gog_galaxyclientservice_privesc) > set SESSION session-id
msf exploit(gog_galaxyclientservice_privesc) > exploit
Required Options
- SESSION: The session to run this module on.
Knowledge Base
Vulnerable Application
GOG Galaxy is a video game management client. One of its Windows services, GalaxyClientService, runs with SYSTEM privileges. In versions 2.0.12 and earlier, and 1.2.64 and earlier, it is possible to communicate with the service and instruct it to execute arbitrary commands as SYSTEM.
A vulnerable version need only be installed on the target machine in order to be exploitable.
Verification Steps
- Start msfconsole.
- Acquire a Meterpreter session.
- Do:
use exploit/windows/local/gog_galaxyclientservice_privesc
- Do:
set SESSION <session_no>
- Do:
exploit
- Verify that you get a Meterpreter session.
Options
WORKING_DIR
The initial working directory of the command.

Error Messages
This module may fail with the following error messages:
- Galaxy Client Service not found
- Unable to determine version
- Unable to determine version from log file
- Galaxy Client version not found
- Vulnerable version found: <VER_NO>
- Galaxy Client version <VER_NO> not vulnerable
- Already running as SYSTEM
- Session type must be Meterpreter session
- Service already running. If the file_path execution fails, try it again in 15 seconds or so.
- GetLastError
- Connection failed. Waiting 2 seconds and trying again...
- Failed to connect to service
- Failed to read response from service (return value from recv(): <RET>). This probably means the exploit failed. :(
Check for the possible causes from the code snippets below found in the module source code. This can often times help in identifying the root cause of the problem.
