Routine

MEDIUM 5.3MITIGATEMITIGATEMITIGATE

CVE-2018-14781 is a medium-severity flaw (CVSS 5.3) affecting 508 minimed insulin pump firmware, 522 paradigm real-time firmware, 722 paradigm real-time firmware. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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.
