Unauthenticated control via unguarded home endpoint

Published Nov 19, 2025 · Updated Nov 19, 2025

Authentication bypass in ITEL ISO FM SFN Adapter firmware ISO2 2.0.0.0 allows remote attackers to take over active web sessions. The WebServer 2.0 /home.html endpoint serves the control panel without validating authentication and associates the requester with an existing authenticated session. An active user or administrator session is required; access permits device control and configuration changes that can interrupt service.
