Service-privileged code execution via unquoted paths
Published Sep 17, 2025 · Updated Sep 17, 2025
Unquoted service paths in OMRON UPS management applications allow local users to execute unauthorized files with service privileges. The applications register Windows service executable paths without surrounding quotation marks, allowing an earlier path segment to resolve as an executable. Administrative local access and an installation path containing spaces are required; affected releases span Standard Edition 2.0.0 and earlier, Basic Edition 1.1.0 and earlier, Slave Agent 5.20 and earlier, Master Agent 5.17 and earlier, and Simple Shutdown Software 2.51 and earlier.
