Last modified

CVE-2022-33971 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. 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.. EPSS estimates a 1.03% chance of exploitation in the next 30 days.
