The failover ipsec implementation in Cisco Adaptive Security Appliance (ASA) Software 9.1 before 9.1(6), 9.2 before 9.2(3.3), and 9.3 before 9.3(3) does not properly validate failover communication messages, which allows remote attackers to reconfigure an ASA device, and consequently obtain administrative control, by sending crafted UDP packets over the local network to the failover interface, aka Bug ID CSCur21069.
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Access control involves the use of several protection mechanisms such as:
When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:
