An issue was discovered in Emote Remote Mouse through 4.0.0.0. Authentication Bypass can occur via Packet Replay. Remote unauthenticated users can execute arbitrary code via crafted UDP packets even when passwords are set.

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).
