Authentication bypass by replay in Smart Switch prior to version 3.7.69.15 allows remote attackers to trigger privileged functions.

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).
