Design/Logic Flaw

Medtronic MyCareLink Smart 25000 all versions contain an authentication protocol vuln where the method used to auth between MCL Smart Patient Reader and MyCareLink Smart mobile app is vulnerable to bypass. This vuln allows attacker to use other mobile device or malicious app on smartphone to auth to the patient’s Smart Reader, fools the device into thinking its communicating with the actual smart phone application when executed in range of Bluetooth.
