CVE-2019-18254

Physical disclosure via unencrypted local storage

Published Jun 29, 2020 · Updated Aug 5, 2024

Missing encryption in BIOTRONIK CardioMessenger II-S T-Line and GSM T4APP 2.20 allows attackers with physical access to disclose medical data. Local storage retains cardiac measurements and the paired implant serial number without encryption at rest, enabling direct recovery from the device. Physical possession is required; the documented consequence is sensitive-data disclosure without reported integrity or availability impact.
