The affected products do not properly enforce mutual authentication with the BIOTRONIK Remote Communication infrastructure. CVE-2019-18246 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). The affected products transmit credentials in cleartext prior to switching to an encrypted communication channel. An attacker can disclose the product 's client credentials for connecting to the BIOTRONIK Remote Communication infrastructure.CVE-2019-18248 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). The affected products allow credential reuse for multiple authentication purposes. An attacker with adjacent access to the CardioMessenger can disclose its credentials used for connecting to the BIOTRONIK Remote Communication infrastructure.CVE-2019-18252 has been assigned to this vulnerability. A CVSS v3 base score of 4.3 has been calculated; the CVSS vector string is (AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N). The affected products do not encrypt sensitive information while at rest. An attacker with physical access to the CardioMessenger can disclose medical measurement data and the serial number from the implanted cardiac device the CardioMessenger is paired with.CVE-2019-18254 has been assigned to this vulnerability. A CVSS v3 base score of 4.6 has been calculated; the CVSS vector string is (AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). The affected products use individual per-device credentials that are stored in a recoverable format. An attacker with physical access to the CardioMessenger can use these credentials for network authentication and decryption of local data in transit.CVE-2019-18256 has been assigned to this vulnerability. A CVSS v3 base score of 4.6 has been calculated; the CVSS vector string is (AV:P/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N).
