CVE-2018-8868
Medtronic MyCareLink Patient Monitor Exposed Dangerous Method or Function
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.
