CVE-2020-24574 (GCVE-0-2020-24574)

Vulnerability from cvelistv5 – Published: 2020-08-21 03:41 – Updated: 2024-08-04 15:19

Summary

The client (aka GalaxyClientService.exe) in GOG GALAXY through 2.0.41 (as of 12:58 AM Eastern, 9/26/21) allows local privilege escalation from any authenticated user to SYSTEM by instructing the Windows service to execute arbitrary commands. This occurs because the attacker can inject a DLL into GalaxyClient.exe, defeating the TCP-based "trusted client" protection mechanism.

Severity

No CVSS data available.
