CVE-2018-0131

A vulnerability in the implementation of RSA-encrypted nonces in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to obtain the encrypted nonces of an Internet Key Exchange Version 1 (IKEv1) session. The vulnerability exists because the affected software responds incorrectly to decryption failures. An attacker could exploit this vulnerability sending crafted ciphertexts to a device configured with IKEv1 that uses RSA-encrypted nonces. A successful exploit could allow the attacker to obtain the encrypted nonces. Cisco Bug IDs: CSCve77140.

Una vulnerabilidad en la implementación de nonces cifrados por RSA en Cisco IOS Software y Cisco IOS XE Software podría permitir que un atacante remoto no autenticado obtenga los nonces cifrados de una sesión IKE v1(Internet Key Exchange Version 1). La vulnerabilidad existe debido a que el software afectado responde incorrectamente a los errores de descifrado. Un atacante podría explotar esta vulnerabilidad para enviar textos cifrados manipulados a u dispositivo configurado con IKEv1 que emplea nonces cifrados por RSA. Su explotación con éxito podría permitir que el atacante obtenga los nonces cifrados. Cisco Bug IDs: CSCve77140.
