CVE-2018-14781

Medtronic MiniMed MMT-500/MMT-503 Remote Controllers Authentication Bypass by Capture-replay

Description

Medtronic MiniMed MMT devices when paired with a remote controller and having the “easy bolus” and “remote bolus” options enabled (non-default), are vulnerable to a capture-replay attack. An attacker can capture the wireless transmissions between the remote controller and the pump and replay them to cause an insulin (bolus) delivery.

Remediation

Workaround:

  • The remote option is turned off in the pump by default.   Medtronic is directing all users to stop using their remote controllers, disable the remote option on their insulin pump, and to return the remote controllers to Medtronic. Medtronic has released additional patient focused information https://www.medtronic.com/security . Additionally, Medtronic will be sending a letter to patients who may still be actively using the remotes in order to inform patients about these security risks, and request patients stop using the remote and return them to Medtronic.
