CVSS: 9.4EPSS: 0%CPEs: 92EXPL: 0CVE-2022-45790 – Omron FINS memory protection susceptible to bruteforce
https://notcve.org/view.php?id=CVE-2022-45790
22 Jan 2024 — The Omron FINS protocol has an authenticated feature to prevent access to memory regions. Authentication is susceptible to bruteforce attack, which may allow an adversary to gain access to protected memory. This access can allow overwrite of values including programmed logic. El protocolo Omron FINS tiene una función autenticada para evitar el acceso a regiones de memoria. La autenticación es susceptible a ataques de fuerza bruta, lo que puede permitir que un adversario obtenga acceso a la memoria protegida... • https://www.cisa.gov/news-events/ics-advisories/icsa-23-262-05 • CWE-307: Improper Restriction of Excessive Authentication Attempts •

19 Jun 2023 — 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 sys... • https://jvn.jp/en/ta/JVNTA91513661 • CWE-306: Missing Authentication for Critical Function •

16 Mar 2023 — 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 • CWE-284: Improper Access Control •
