In SOOIL Developments Co., Ltd Diabecare RS, AnyDana-i and AnyDana-A, the communication protocol of the insulin pump and its AnyDana-i and AnyDana-A mobile applications lacks replay protection measures, which allows unauthenticated, physically proximate attackers to replay communication sequences via Bluetooth Low Energy.

Weakness

A capture-replay flaw exists when the design of the product makes it possible for a malicious user to sniff network traffic and bypass authentication by replaying it to the server in question to the same effect as the original message (or with minor changes).
