Descriptions

The Flex-VPN load-balancing feature in the ipsec-ikev2 implementation in Cisco IOS before 15.1(1)SY3 does not require authentication, which allows remote attackers to trigger the forwarding of VPN traffic to an attacker-controlled destination, or the discarding of this traffic, by arranging for an arbitrary device to become a cluster member, aka Bug ID CSCub93641.

La funcionalidad Flex-VPN load-balancing en la implementación ipsec-ikev2 en Cisco IOS anterior a 15.1(1)SY3 no requiere autenticación, lo que permite a atacantes remotos provocar el reenvío de trafico VPN hacia un destino controlado por el atacante, o el descarte de este trafico, mediante la organización de un dispositivo arbitrario como miembro de un cluster, también conocido como Bug ID CSCub93641.
