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 •

https://notcve.org/view.php?id=CVE-2023-0811
Omron CJ1M unit v4.0 and prior has improper access controls on the memory region where the UM password is stored. If an adversary issues a PROGRAM AREA WRITE command to a specific memory region, they could overwrite the password. This may lead to disabling UM protections or setting a non-ASCII password (non-keyboard characters) and preventing an engineer from viewing or modifying the user program. • https://www.cisa.gov/news-events/ics-advisories/icsa-23-073-01 https://www.ia.omron.com/product/vulnerability/OMSR-2023-001_en.pdf • CWE-284: Improper Access Control •

Active debug code exists in OMRON CP1L-EL20DR-D all versions, which may lead to a command that is not specified in FINS protocol being executed without authentication. A remote unauthenticated attacker may read/write in arbitrary area of the device memory, which may lead to overwriting the firmware, causing a denial-of-service (DoS) condition, and/or arbitrary code execution. Existe un código de depuración activo en OMRON CP1L-EL20DR-D en todas las versiones, lo que puede provocar que un comando que no está especificado en el protocolo FINS se ejecute sin autenticación. Un atacante remoto no autenticado puede leer/escribir en un área arbitraria de la memoria del dispositivo, lo que puede provocar la sobrescritura del firmware, lo que provoca una condición de denegación de servicio (DoS) y/o la ejecución de código arbitrario. • https://jvn.jp/en/vu/JVNVU97575890/index.html •
