The vulnerability is due to inadequate provisioning of kernel parameters for the maximum number of TCP connections and SYN backlog. An attacker could exploit this vulnerability by sending a flood of crafted TCP packets to an affected device. A successful exploit could allow the attacker to block TCP listening ports that are used by the health monitor API. This vulnerability only affects customers who use the health monitor API."}, {"lang": "es", "value": "Una vulnerabilidad en la administraci\u00f3n de recursos del sistema de Cisco Elastic Services Controller (ESC), podr\u00eda permitir a un atacante no autenticado remoto causar una denegaci\u00f3n de servicio (DoS) a la API del monitor de salud en un dispositivo afectado. La vulnerabilidad es debido al aprovisionamiento inadecuado de los par\u00e1metros del kernel para el n\u00famero m\u00e1ximo de conexiones TCP y atrasos de SYN.
