The attacker must have valid IKEv1 VPN credentials to exploit this vulnerability.\r\n\r This vulnerability is due to improper validation of IKEv1 phase 2 parameters before the IPsec security association creation request is handed off to the hardware cryptographic accelerator of an affected device. An attacker could exploit this vulnerability by sending crafted IKEv1 messages to the affected device. A successful exploit could allow the attacker to cause the device to reload."}, {"lang": "es", "value": "Una vulnerabilidad en la implementaci\u00f3n de Intercambio de Claves por Internet versi\u00f3n 1 (IKEv1) del software Cisco IOS XE podr\u00eda permitir que un atacante remoto autenticado provoque una denegaci\u00f3n de servicio (DoS). El atacante debe tener credenciales VPN IKEv1 v\u00e1lidas para explotar esta vulnerabilidad. Esta vulnerabilidad se debe a una validaci\u00f3n incorrecta de los par\u00e1metros de fase 2 de IKEv1 antes de que la solicitud de creaci\u00f3n de la asociaci\u00f3n de seguridad IPsec se transfiera al acelerador criptogr\u00e1fico de hardware de un dispositivo afectado. Un atacante podr\u00eda explotar esta vulnerabilidad enviando mensajes IKEv1 manipulados al dispositivo afectado. Una explotaci\u00f3n exitosa podr\u00eda permitir al atacante provocar la recarga del dispositivo."}], "lastModified": "2025-05-08T14:39:09.683", "sourceIdentifier": "psirt@cisco.com"}
