CVE-2019-6538 is a medium-severity vulnerability rated 6.5/10 on the CVSS scale. 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. EPSS estimates a 0.84% chance of exploitation in the next 30 days.

Description

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.
