FINS (Factory Interface Network Service) is a message communication protocol, which is designed to be used in closed FA (Factory Automation) networks, and is used in FA networks composed of OMRON products. Multiple OMRON products that implement FINS protocol contain following security issues -- (1)Plaintext communication, and (2)No authentication required. When FINS messages are intercepted, the contents may be retrieved. When arbitrary FINS messages are injected, any commands may be executed on, or the system information may be retrieved from, the affected device. Affected products and versions are as follows: SYSMAC CS-series CPU Units, all versions, SYSMAC CJ-series CPU Units, all versions, SYSMAC CP-series CPU Units, all versions, SYSMAC NJ-series CPU Units, all versions, SYSMAC NX1P-series CPU Units, all versions, SYSMAC NX102-series CPU Units, all versions, and SYSMAC NX7 Database Connection CPU Units (Ver.1.16 or later) • https://jvn.jp/en/ta/JVNTA91513661 https://jvn.jp/ta/JVNTA91513661 https://www.cisa.gov/uscert/ics/advisories/icsa-22-179-02 https://www.fa.omron.co.jp/product/vulnerability/OMSR-2023-003_ja.pdf https://www.ia.omron.com/product/vulnerability/OMSR-2023-003_en.pdf https://www.us-cert.gov/ics/advisories/icsa-19-346-02 https://www.us-cert.gov/ics/advisories/icsa-20-063-03 • CWE-306: Missing Authentication for Critical Function •

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. • https://www.cisa.gov/uscert/ics/advisories/icsa-22-179-02 https://www.forescout.com/blog • CWE-347: Improper Verification of Cryptographic Signature •
