CVE-2023-22282

Local privilege escalation via unquoted service path

Published Apr 11, 2023 · Updated Feb 11, 2025

Unquoted service paths in ELECOM WAB-MAT 5.0.0.8 and earlier allow local users to execute code with Windows service privileges. The installer registers the Windows service executable path without quotation marks, so Windows can resolve a planted executable earlier in the spaced path. A local user who can write a malicious executable to the selected path gains the service account's privileges when the service starts.
