CVE-2025-11649Public exploit

Root shell access via immutable UART password

Published Oct 12, 2025 · Updated Oct 20, 2025

Hard-coded root credentials in Tomofun Furbo 360 and Furbo Mini firmware allow physically proximate attackers to obtain a root shell via UART. The root password hash is stored in /etc/shadow on a read-only firmware partition, so every device retains the same owner-immutable credential. Physical teardown, UART attachment, and knowledge of the recovered password are required; affected firmware extends through FB0035_FW_036 and MC0020_FW_074, and successful login permits inspection or modification of device credentials and firmware.
