Abbott Laboratories pacemakers manufactured prior to Aug 28, 2017 do not restrict or limit the number of correctly formatted "RF wake-up" commands that can be received, which may allow a nearby attacker to repeatedly send commands to reduce pacemaker battery life. CVSS v3 base score: 5.3, CVSS vector string: AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H. Abbott has developed a firmware update to help mitigate the identified vulnerabilities.

The authentication algorithm in Abbott Laboratories pacemakers manufactured prior to Aug 28, 2017, which involves an authentication key and time stamp, can be compromised or bypassed, which may allow a nearby attacker to issue unauthorized commands to the pacemaker via RF communications. CVSS v3 base score: 7.5, CVSS vector string: AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H. Abbott has developed a firmware update to help mitigate the identified vulnerabilities.
