CVE-2025-11643Public exploitNetwork attack vector

Device impersonation via non-unique MQTT credentials

Published Oct 12, 2025 · Updated Oct 18, 2025

Hard-coded credentials in Tomofun Furbo 360 and Furbo Mini firmware allow remote attackers to impersonate devices on the MQTT service. The nested furbo_img filesystem stores a non-unique MQTT client certificate and private key that extracted firmware exposes for reuse. Successful reuse reveals device identifiers and activity across deployed cameras; firmware retrieval and decryption make exploitation high-complexity.
