Medtronic Conexus Radio Frequency Telemetry Protocol (Update C)
The Conexus telemetry protocol utilized within this ecosystem 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.CVE-2019-6538 has been assigned to this vulnerability. A CVSS v3 base score of 9.3 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:H/A:H). The Conexus telemetry protocol utilized within this ecosystem does not implement encryption. An attacker with adjacent short-range access to a target product can listen to communications, including the transmission of sensitive data.CVE-2019-6540 has been assigned to this vulnerability. A CVSS v3 base score of 6.5 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
