All versions of Telecrane F25 Series Radio Controls before 00.0A use fixed codes that are reproducible by sniffing and re-transmission. This can lead to unauthorized replay of a command, spoofing of an arbitrary message, or keeping the controlled load in a permanent stop state.

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).
