In JUUKO K-808, an attacker could specially craft a packet that encodes an arbitrary command, which could be executed on the K-808 (Firmware versions prior to numbers ending …9A, …9B, …9C, etc.).

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).
