KeyIdentity LinOTP before 2.10.5.3 has Incorrect Access Control (issue 1 of 2).

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).
