CVE-2020-27258

Keypad lock PIN disclosure via Bluetooth

Published Jan 19, 2021 · Updated Aug 4, 2024

Information disclosure in SOOIL Developments Co., Ltd Diabecare RS, AnyDana-i and AnyDana-A before version 3.0 allows unauthenticated attackers to extract the insulin pump keypad lock PIN via Bluetooth Low Energy. The communication protocol exposes the PIN to unauthenticated Bluetooth peers instead of protecting this credential. A physically proximate attacker able to communicate over Bluetooth can obtain the PIN; public advisories describe testing-based risk and do not establish exploitation in real-world use.
