Cisco Firepower Threat Defense and Cisco ASA with FirePOWER Module Denial of Service Vulnerability

A vulnerability in the access control policy of Cisco Firepower System Software could allow an authenticated, remote attacker to cause an affected system to stop inspecting and processing packets, resulting in a denial of service (DoS) condition.

The vulnerability is due to improper SSL policy handling by the affected software when packets are passed through the sensing interfaces of an affected system. An attacker could exploit this vulnerability by sending crafted packets through a targeted system.

There are no workarounds that address this vulnerability.
