The advisory points out:

A vulnerability in the failover ipsec feature of Cisco ASA Software could allow an unauthenticated, adjacent attacker to submit configuration commands to any of the failover units via the failover interface. As a result, an attacker could be able to take full control of both the active and standby failover units. The vulnerability is due to improper handling of secured failover communication messages when the failover ipsec feature is configured. An attacker could exploit this vulnerability by sending crafted UDP packets directed to the failover interface IP address. An attacker needs IP connectivity to the failover interface IP addresses to exploit this vulnerability.
