GSD-2019-6538

Vulnerability from gsd - Updated: 2023-12-13 01:23

Details

The Conexus telemetry protocol utilized within Medtronic MyCareLink Monitor versions 24950 and 24952, CareLink Monitor version 2490C, CareLink 2090 Programmer, Amplia CRT-D, Claria CRT-D, Compia CRT-D, Concerto CRT-D, Concerto II CRT-D, Consulta CRT-D, Evera ICD, Maximo II CRT-D and ICD, Mirro ICD, Nayamed ND ICD, Primo ICD, Protecta ICD and CRT-D, Secura ICD, Virtuoso ICD, Virtuoso II ICD, Visia AF ICD, and Viva CRT-D does not implement authentication or authorization. An attacker with adjacent short-range access to an affected product, in situations where the product’s radio is turned on, can inject, replay, modify, and/or intercept data within the telemetry communication. This communication protocol provides the ability to read and write memory values to affected implanted cardiac devices; therefore, an attacker could exploit this communication protocol to change memory in the implanted cardiac device.
