Authentication bypass by capture-replay vulnerability exists in Machine automation controller NJ series all models V 1.48 and earlier, Machine automation controller NX7 series all models V1.28 and earlier, Machine automation controller NX1 series all models V1.48 and earlier, Automation software Sysmac Studio all models V1.49 and earlier, and Programmable Terminal (PT) NA series NA5-15W/NA5-12W/NA5-9W/NA5-7W models Runtime V1.15 and earlier, which may allow a remote attacker who can analyze the communication between the affected controller and automation software Sysmac Studio and/or a Programmable Terminal (PT) to access the controller.
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).
