Lifecycle Timeline
1DescriptionNVD
The Omron SYSMAC Nx product family PLCs (NJ series, NY series, NX series, and PMAC series) through 2022-005-18 lack cryptographic authentication. These PLCs are programmed using the SYMAC Studio engineering software (which compiles IEC 61131-3 conformant POU code to native machine code for execution by the PLC's runtime). The resulting machine code is executed by a runtime, typically controlled by a real-time operating system. The logic that is downloaded to the PLC does not seem to be cryptographically authenticated, allowing an attacker to manipulate transmitted object code to the PLC and execute arbitrary machine code on the processor of the PLC's CPU module in the context of the runtime. In the case of at least the NJ series, an RTOS and hardware combination is used that would potentially allow for memory protection and privilege separation and thus limit the impact of code execution. However, it was not confirmed whether these sufficiently segment the runtime from the rest of the RTOS.
AnalysisAI
The Omron SYSMAC Nx product family PLCs (NJ series, NY series, NX series, and PMAC series) through 2022-005-18 lack cryptographic authentication. Rated critical severity (CVSS 9.8), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.
Technical ContextAI
This vulnerability is classified under CWE-347. The Omron SYSMAC Nx product family PLCs (NJ series, NY series, NX series, and PMAC series) through 2022-005-18 lack cryptographic authentication.

In the case of at least the NJ series, an RTOS and hardware combination is used that would potentially allow for memory protection and privilege separation and thus limit the impact of code execution. However, it was not confirmed whether these sufficiently segment the runtime from the rest of the RTOS. Affected products include: Omron Nx701-1600 Firmware, Omron Nx701-1620 Firmware, Omron Nx701-1700 Firmware, Omron Nx701-1720 Firmware, Omron Nx701-Z600 Firmware. Version information: through 2022.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Apply vendor patches when available. Implement network segmentation and monitoring as interim mitigations.
