Denial-of-service (DoS) vulnerability due to improper validation of specified type of input issue exists in the built-in EtherNet/IP port of the CJ Series CJ2 CPU unit and the communication function of the CS/CJ Series EtherNet/IP unit. If an affected product receives a packet which is specially crafted by a remote unauthenticated attacker, the unit of the affected product may fall into a denial-of-service (DoS) condition. Affected products/versions are as follows: CJ2M CPU Unit CJ2M-CPU3[] Unit version of the built-in EtherNet/IP section Ver. 2.18 and earlier, CJ2H CPU Unit CJ2H-CPU6[]-EIP Unit version of the built-in EtherNet/IP section Ver. 3.04 and earlier, CS/CJ Series EtherNet/IP Unit CS1W-EIP21 V3.04 and earlier, and CS/CJ Series EtherNet/IP Unit CJ1W-EIP21 V3.04 and earlier. • https://jvn.jp/en/vu/JVNVU92193064 https://www.ia.omron.com/product/vulnerability/OMSR-2023-006_en.pdf • CWE-1284: Improper Validation of Specified Quantity in Input •

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 •

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 •
