An attacker could exploit this vulnerability by authenticating to a device and submitting crafted input to the affected command. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system of the affected device with root-level privileges."}, {"lang": "es", "value": "Una vulnerabilidad en la interfaz de gesti\u00f3n basada en web de Cisco FXOS Software y Cisco UCS Manager Software podr\u00eda permitir a un atacante autenticado y local con privilegios administrativos realizar ataques de inyecci\u00f3n de comandos en un sistema afectado y elevar privilegios a root.\n\nEsta vulnerabilidad se debe a una validaci\u00f3n de entrada insuficiente de los argumentos de comando proporcionados por el usuario. Un atacante podr\u00eda explotar esta vulnerabilidad autentic\u00e1ndose en un dispositivo y enviando una entrada manipulada al comando afectado.
