The vulnerability is due to insufficient TLS client certificate validations for certificates sent between the various components of an ACI fabric. An attacker who has possession of a certificate that is trusted by the Cisco Manufacturing CA and the corresponding private key could exploit this vulnerability by presenting a valid certificate while attempting to connect to the targeted device. An exploit could allow the attacker to gain full control of all other components within the ACI fabric of an affected device."}, {"lang": "es", "value": "Una vulnerabilidad en la funcionalidad de validaci\u00f3n de certificados de Transport Layer Security (TLS) del software Nexus 9000 Series Switch de Cisco en modo Application Centric Infrastructure (ACI), podr\u00eda permitir a un atacante remoto no autenticado realizar una autenticaci\u00f3n no segura del cliente TLS en un dispositivo afectado. La vulnerabilidad es debido a que son insuficientes las validaciones de certificados del cliente TLS para los certificados enviados entre los distintos componentes de un ACI fabric. Un atacante que posea un certificado en el que conf\u00ede Cisco Manufacturing CA y la clave privada correspondiente podr\u00eda explotar esta vulnerabilidad presentando un certificado v\u00e1lido mientras intenta conectarse al dispositivo de destino.
