Weak security in the transmitter of Blitzwolf BW-IS22 Smart Home Security Alarm v1.0 allows attackers to gain full access to the system via a code replay attack.

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).
