An attacker could exploit this vulnerability by sending crafted IKEv2 packets to an affected device. A successful exploit could allow the attacker to cause an infinite loop that exhausts resources and could cause the device to reload."}, {"lang": "es", "value": "Una vulnerabilidad en la funci\u00f3n IKEv2 del software Cisco IOS, IOS XE, Secure Firewall ASA y Secure FTD podr\u00eda permitir que un atacante remoto no autenticado reinicie el dispositivo, lo que resulta en una denegaci\u00f3n de servicio (DoS). Esta vulnerabilidad se debe al procesamiento incorrecto de paquetes IKEv2. Un atacante podr\u00eda explotar esta vulnerabilidad enviando paquetes IKEv2 manipulados a un dispositivo afectado.
