TITLE

Cisco IOS and Cisco IOS XE Vulnerability related to cryptographic strength in software

Trust: 0.8

sources: JVNDB: JVNDB-2018-009312

DESCRIPTION

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. Cisco IOS and Cisco IOS XE The software is vulnerable to cryptographic strength. Vendors have confirmed this vulnerability Bug ID CSCve77140 It is released as.Information may be obtained
