CVE-2020-27256

Therapy-setting modification via hard-coded physician PIN

Published Jan 19, 2021 · Updated Aug 4, 2024

Hard-coded credentials in SOOIL Dana Diabecare RS, AnyDana-i, and AnyDana-A before 3.0 allow attackers to alter insulin therapy settings. The pump's physician menu accepts a manufacturer-embedded physician PIN rather than a device-specific credential. Physical access to the pump is required, after which the shared PIN grants access to therapy controls and permits changes to insulin delivery parameters.
