CVE-2025-10199

SYSTEM privilege escalation via unquoted service path

Published Sep 9, 2025 · Updated Nov 3, 2025

Unquoted service path handling in LizardByte Sunshine 2025.122.141614 allows local users to execute code with SYSTEM privileges. The CVE record attributes the flaw to an unquoted Windows service path, where a writable earlier path segment can redirect service startup to an attacker-controlled executable. CERT/CC instead assigns CVE-2025-10199 to DLL search-order hijacking and the service-path flaw to CVE-2025-10198, leaving the precise mechanism disputed in public records.
