The vulnerability is due to improper input validation when handling Cluster Management Protocol (CMP) messages. An attacker could exploit this vulnerability by sending a malicious CMP message to an affected device. A successful exploit could allow the attacker to cause the switch to crash and reload or to hang, resulting in a DoS condition. If the switch hangs it will not reboot automatically, and it will need to be power cycled manually to recover."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n de la caracter\u00edstica del cl\u00faster en Cisco IOS Software y Cisco IOS XE Software podr\u00eda permitir que un atacante adyacente no autenticado desencadene una condici\u00f3n de denegaci\u00f3n de servicio (DoS) en un dispositivo afectado.
