Anviz access control devices are vulnerable to replay attacks which could allow attackers to intercept and replay open door requests.
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).
