Communications between Medtronic MiniMed MMT pumps and wireless accessories are transmitted in cleartext. A sufficiently skilled attacker could capture these transmissions and extract sensitive information, such as device serial numbers.

Medtronic MMT 508 MiniMed insulin pump, 522 / MMT - 722 Paradigm REAL-TIME, 523 / MMT - 723 Paradigm Revel, 523K / MMT - 723K Paradigm Revel, and 551 / MMT - 751 MiniMed 530G communications between the pump and wireless accessories are transmitted in cleartext. A sufficiently skilled attacker could capture these transmissions and extract sensitive information, such as device serial numbers.

Communications between the pump and wireless accessories are transmitted in cleartext. A sufficiently skilled attacker could capture these transmissions and extract sensitive information, such as device serial numbers.CVE-2018-10634 has been assigned to this vulnerability. A CVSS v3 base score of 4.8 has been assigned; the CVSS vector string is (AV:A/AC:H/PR:N/UI:R/S:U/C:H/I:N/A:N). The models identified above, 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.CVE-2018-14781 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been assigned; the CVSS vector string is (AV:A/AC:H/PR:N/UI:N/S:U/C:N/I:H/A:N).
