CVE-2022-33971

EUVD-2022-37007

04.07.2022, 02:15

Authentication bypass by capture-replay vulnerability exists in Machine automation controller NX7 series all models V1.28 and earlier, Machine automation controller NX1 series all models V1.48 and earlier, and Machine automation controller NJ series all models V 1.48 and earlier, which may allow an adjacent attacker who can analyze the communication between the controller and the specific software used by OMRON internally to cause a denial-of-service (DoS) condition or execute a malicious program.

Common Weakness Enumeration

CWE-294 - Authentication Bypass by Capture-replay
A capture-replay flaw exists when the design of the software 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).
