CVE-2025-14849Network attack vector

Authenticated code execution via dangerous file upload

Published Dec 18, 2025 · Updated Dec 18, 2025

Unrestricted file upload in Advantech WebAccess/SCADA 9.2.1 allows remote authenticated users to execute arbitrary code over the network. The public advisory identifies acceptance of a dangerous uploaded file but does not disclose the affected upload handler or missing validation operation. Low-privileged product access is required; successful exploitation runs attacker-supplied code on the SCADA server, while the precise upload endpoint remains undisclosed.
