Meross MSG100 devices before 3.2.3 allow an attacker to replay the same data or similar data (e.g., an attacker who sniffs a Close message can transmit an acceptable Open message).

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).
