→CVE-2025-59171 is a path traversal vulnerability in a device dependency of Advantech DeviceOn/iEdge (version 2.0.2 and prior) that allows an unauthenticated remote attacker to read arbitrary files or bypass authentication — no authentication required (PR:N), network-exploitable (AV:N), low complexity (AC:L). ↗
→Monitor for unauthenticated HTTP requests to Advantech DeviceOn/iEdge endpoints containing path traversal sequences (e.g., '../') targeting file read or authentication bypass, particularly on internet-exposed instances. ↗
→Affected product version: Advantech DeviceOn/iEdge version 2.0.2 and prior. Flag any such version exposed to the network. ↗

·CVE-2025-59171 is specifically a path traversal in a *device dependency* (third-party/bundled component), not directly in the core DeviceOn/iEdge application code itself — detection should account for the dependency layer. ↗
·Advantech has declared DeviceOn/iEdge end-of-life; no patch will be issued. The recommended mitigation is migration to DeviceOn (the successor product), not a version update. ↗
·No known public exploitation specifically targeting CVE-2025-59171 has been reported to CISA at time of publication. ↗
