CVE-2021-38394

Special-settings access via cloned hardware key

Published Oct 4, 2021 · Updated Sep 16, 2024

Hardware reverse engineering in Boston Scientific ZOOM LATITUDE Model 3120 allows physically proximate attackers to clone a privileged hardware key. The appliance permits extraction of the binary that validates the hardware key, exposing enough validation logic to reproduce a valid key physically. Physical access to the programmer is required, and the cloned key grants access to special settings; the appliance has no network connectivity.
