CVE-2025-54081Public exploit

SYSTEM code execution via unquoted service path

Published Sep 23, 2025 · Updated Sep 23, 2025

Privilege escalation in LizardByte Sunshine before 2025.923.33222 allows local users to execute arbitrary code as SYSTEM on Windows. SunshineService stores the sunshinesvc.exe path without quotes, so SCM probes earlier path segments and launches an attacker-written executable. Exploitation requires a spaced install path and write access to a preceding directory; the default path is generally protected.
