CVSS: 8.6EPSS: 0%CPEs: 82EXPL: 0CVE-2022-45794 – Omron CJ-series and CS-series unauthenticated filesystem access.
https://notcve.org/view.php?id=CVE-2022-45794
An attacker with network access to the affected PLC (CJ-series and CS-series PLCs, all versions) may use a network protocol to read and write files on the PLC internal memory and memory card. Un atacante con acceso a la red del PLC afectado (PLC de las series CJ y CS, todas las versiones) puede utilizar un protocolo de red para leer y escribir archivos desde la memoria interna y la tarjeta de memoria del PLC. • https://www.dragos.com/advisory/omron-plc-and-engineering-software-network-and-file-format-access https://www.fa.omron.co.jp/product/security/assets/pdf/en/OMSR-2023-002_en.pdf • 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 •

The Omron SYSMAC Cx product family PLCs (CS series, CJ series, and CP series) through 2022-05-18 lack cryptographic authentication. They utilize the Omron FINS (9600/TCP) protocol for engineering purposes, including downloading projects and control logic to the PLC. This protocol has authentication flaws as reported in FSCT-2022-0057. Control logic is downloaded to PLC volatile memory using the FINS Program Area Read and Program Area Write commands or to non-volatile memory using other commands from where it can be loaded into volatile memory for execution. The logic that is loaded into and executed from the user program area exists in compiled object code form. • https://www.cisa.gov/uscert/ics/advisories/icsa-22-179-02 https://www.forescout.com/blog • CWE-347: Improper Verification of Cryptographic Signature •

In Omron CS series, CJ series, and CP series PLCs through 2022-05-18, the password for access to the Web UI is stored in memory area D1449...D1452 and can be read out using the Omron FINS protocol without any further authentication. En los PLC de las series CS, CJ y CP de Omron versiones hasta 18-05-2022, la contraseña de acceso a la Interfaz de Usuario Web es almacenada en el área de memoria D1449...D1452 y puede leerse mediante el protocolo FINS de Omron sin necesidad de ninguna otra autenticación. • https://www.cisa.gov/uscert/ics/advisories/icsa-22-179-02 https://www.forescout.com/blog • CWE-312: Cleartext Storage of Sensitive Information •

https://notcve.org/view.php?id=CVE-2022-31204
Omron CS series, CJ series, and CP series PLCs through 2022-05-18 use cleartext passwords. They feature a UM Protection setting that allows users or system integrators to configure a password in order to restrict sensitive engineering operations (such as project/logic uploads and downloads). This password is set using the OMRON FINS command Program Area Protect and unset using the command Program Area Protect Clear, both of which are transmitted in cleartext. Los PLC de las series CS, CJ y CP de Omron versiones hasta 18-05-2022, usan contraseñas en texto sin cifrar. Disponen de un ajuste de protección de UM que permite a usuarios o a integradores de sistemas configurar una contraseña para restringir las operaciones de ingeniería confidenciales (como las cargas y descargas de proyectos/lógicas). • https://www.cisa.gov/uscert/ics/advisories/icsa-22-179-02 https://www.forescout.com/blog • CWE-319: Cleartext Transmission of Sensitive Information •
