CVE-2025-67653Network attack vector

Authenticated file-existence disclosure via path traversal

Published Dec 18, 2025 · Updated Dec 18, 2025

Path traversal in Advantech WebAccess/SCADA 9.2.1 allows remote authenticated users to detect arbitrary file existence. The published advisory does not identify the affected endpoint or disclose how its path handler fails to confine attacker-controlled pathnames. Low-privileged authenticated network access is required, and the demonstrated consequence is limited to a file-existence oracle rather than file-content disclosure or modification.
