CVE-2022-29958
Estado: ModificadaCrítica (9.8)—
JTEKT TOYOPUC PLCs through 2022-04-29 do not ensure data integrity. They utilize the unauthenticated CMPLink/TCP protocol for engineering purposes, including downloading projects and control logic to the PLC. Control logic is downloaded to the PLC on a block-by-block basis with a given memory address and a blob of machine code. The logic that is downloaded to the PLC is not cryptographically authenticated, allowing an attacker to execute arbitrary machine code on the PLC's CPU module in the context of the runtime. In the case of the PC10G-CPU, and likely for other CPU modules of the TOYOPUC family, a processor without MPU or MMU is used and this no memory protection or privilege-separation capabilities are available, giving an attacker full control over the CPU.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Puntuación base: 9.8
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.59%

Usan el protocolo CMPLink/TCP no autenticado para fines de ingeniería, incluyendo la descarga de proyectos y lógica de control al PLC. La lógica de control es descargada en el PLC bloque por bloque con una dirección de memoria determinada y un bloque de código de máquina. La lógica que es descargada en el PLC no está autenticada criptográficamente, lo que permite a un atacante ejecutar código máquina arbitrario en el módulo CPU del PLC en el contexto del tiempo de ejecución. En el caso de la PC10G-CPU, y probablemente para otros módulos de CPU de la familia TOYOPUC, Es usado un procesador sin MPU o MMU y esto sin protección de memoria o capacidades de separación de privilegios, dando a un atacante el control total sobre la CPU."
