Technical ContextAI · show details

This vulnerability is classified under CWE-749. Medtronic 24950 MyCareLink Monitor and 24952 MyCareLink Monitor contains debug code meant to test the functionality of the monitor's communication interfaces, including the interface between the monitor and implantable cardiac device. An attacker with physical access to the device can exploit other vulnerabilities to access this debug functionality. This debug functionality provides the ability to read and write arbitrary memory values to implantable cardiac devices via inductive or short range wireless protocols. An attacker with close physical proximity to a target implantable cardiac device can use this debug functionality. Affected products include: Medtronic 24950 Mycarelink Monitor Firmware, Medtronic 24952 Mycarelink Monitor Firmware.

What every action level means

Emergency Immediate action required. Criteria: CRITICAL + in CISA KEV (actively exploited) without patch, OR CRITICAL + EPSS > 30% without patch, OR CRITICAL + active threat signals without patch.

Act Now Prioritize within 24-48h. Criteria: in KEV with patch available, OR CRITICAL + public POC, OR HIGH + EPSS > 10%, OR CRITICAL + active threat, OR any CRITICAL severity.

This Week Schedule remediation this week. Criteria: HIGH severity (CVSS 7.0-8.9). Patch within normal change window.

This Month Plan within 30 days. Criteria: MEDIUM severity (CVSS 4.0-6.9), lower exploitation probability. Include in regular patch cycle.

Monitor Track and reassess. Criteria: LOW severity (CVSS 0.1-3.9), minimal exploitation risk. No immediate action needed.
