CVE-2025-59171Network attack vector

Unauthenticated file read via vulnerable dependency

Published Nov 6, 2025 · Updated Nov 6, 2025

Path traversal in Advantech DeviceOn/iEdge 2.0.2 and earlier allows remote attackers to read arbitrary files or bypass authentication. CISA identifies a vulnerable device dependency and CWE-22 but does not disclose the dependency, request path, or failed boundary check. The affected service is network reachable without authentication, and the documented consequences are confidentiality loss or authentication bypass.
