Description:Summary:
A vulnerability in the VPN code of Cisco ASA Software could
allow an authenticated, remote attacker to submit configuration commands to the standby unit via
the failover interface. As result, an attacker could be able to take full control of both the
active and standby failover units.

vulnerability by connecting to a targeted device and sending malicious configuration requests
through the failover interface to the standby unit. The attacker could modify the configuration
to take control over both the standby and active units, resulting in complete device compromise.

Affected Software/OS:
Cisco ASA version 7.2, 8.2, 8.3, 8.4, 8.6, 9.0, 9.1, 9.2 and
