standalone NX-OS mode that are running Cisco NX-OS Software could allow an unauthenticated, remote attacker to create, delete, or overwrite arbitrary files with root privileges on the device. This vulnerability exists because TCP port 9075 is incorrectly configured to listen and respond to external connection requests. An attacker could exploit this vulnerability by sending crafted TCP packets to an IP address that is configured on a local interface on TCP port 9075. A successful exploit could allow the attacker to create, delete, or overwrite arbitrary files, including sensitive files that are related to the device configuration. For example, the attacker could add a user account without the device administrator knowing."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n de un servicio de administraci\u00f3n de archivos interno para Cisco Nexus 3000 Series Switches y Cisco Nexus 9000 Series Switches en modo NX-OS dedicado que ejecutan el software Cisco NX-OS podr\u00eda permitir a un atacante remoto no autenticado crear, eliminar o sobrescribir archivos arbitrarios con privilegios de root en el dispositivo. Esta vulnerabilidad se presenta porque el puerto TCP 9075 est\u00e1 configurado incorrectamente para escuchar y responder a peticiones de conexi\u00f3n externa. Un atacante podr\u00eda explotar esta vulnerabilidad mediante el env\u00edo de paquetes TCP dise\u00f1ados a una direcci\u00f3n IP configurada en una interfaz local en el puerto TCP 9075.
