This vulnerability has a CVSS 3.1 base score of 9.8, rated CRITICAL. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
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
Remediation
Check the references section for vendor advisories and patches from omron. Update nx701-1600_firmware to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
