CVE-2024-7206

TLS interception and cloning via extractable firmware

Published Oct 8, 2024 · Updated Oct 8, 2024

Firmware extraction in SONOFF Zigbee Bridge Pro 2.0.0 and earlier allows physically proximate attackers to obtain device secrets. An exposed serial interface permits firmware export; the image contains reusable secrets and a replaceable pinned certificate, and accepts repackaged modified firmware. Exploitation requires disassembly and a serial connection, after which the modified certificate enables interception of device-to-cloud TLS traffic and device cloning.
