CVE-2020-24686
Estado: ModificadaAlta (7.5)—
Las vulnerabilidades pueden ser explotadas para causar que al componente visualization web del PLC detenerse y que no responda, conllevando a usuarios genuinos perder la visibilidad remota del estado del PLC. Si un usuario intenta iniciar sesión en el PLC mientras es explotada esta vulnerabilidad, el PLC mostrará un estado de error y rechazará las conexiones con Automation Builder. La ejecución de la aplicación del PLC no está afectada por esta vulnerabilidad. Este problema afecta a los productos ABB AC500 V2 con Ethernet integrado
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
