CVE-2023-53970Public exploitNetwork attack vector

Unauthenticated transmitter reset via IP-bound session reuse

Published Dec 22, 2025 · Updated Dec 22, 2025

Authentication bypass in SFT DAB 600/C firmware 1.9.3 allows remote attackers to reset the transmitter through its management API. The deviceManagement.cgx endpoint treats requests from an IP address associated with an established session as authorized and accepts reset:true without credentials. An attacker must share the victim session's NAT-visible address and await an active session; the demonstrated consequence is a board reset and broadcast-service interruption.
