Root access via shared hard-coded password
Published Aug 15, 2024 · Updated Aug 15, 2024
Use of hard-coded credentials in GNCC C2 Indoor Security Camera 1080P firmware allows physically proximate attackers to obtain the root hash. The administrative shell exposes /etc/shadow, where two tested devices contained the same root-account hash instead of unique credentials. Physical UART access and recovery of the plaintext password from that hash are required; the research did not recover it, but reuse enables root login on another camera.
