A vulnerability in the VPN configuration management of Cisco FireSIGHT System Software could allow an unauthenticated, remote attacker to bypass VPN security due to unintended side effects of dynamic configuration changes that could allow an attacker to bypass configured policies. The vulnerability is due to incorrect management of the configured interface names and VPN parameters when dynamic CLI configuration changes are performed. An attacker could exploit this vulnerability by sending packets through an interface on the targeted device. A successful exploit could allow the attacker to bypass configured VPN policies. Cisco Bug IDs: CSCvh49388.
