CVE-2022-50928Public exploit

Local privilege escalation via unquoted service path

Published Jan 13, 2026 · Updated Jan 13, 2026

Unquoted service path in IVT Corporation BlueSoleil 5.4.277 allows local users to execute code with LocalSystem privileges. The BlueSoleilCS Windows service registers C:\Program Files\IVT Corporation\BlueSoleil\BlueSoleilCS.exe without quotes, so Windows can resolve an attacker-planted executable from an earlier path segment. Exploitation requires low-privileged local access and write permission to a searched path segment; service startup then runs the planted code as LocalSystem.
