Medtronic MyCareLink Smart 25000 contains an authentication protocol vulnerability where the method used to authenticate between the MCL Smart Patient Reader and the Medtronic MyCareLink Smart mobile app is vulnerable to bypass. This vulnerability enables an attacker to use another mobile device or malicious application on the patient’s smartphone to authenticate to the patient’s Medtronic Smart Reader, fooling the device into believing it is communicating with the original Medtronic smart phone application when executed within range of Bluetooth communication.
