If an ASA or router is getting encaps but not decaps, this means it is encrypting the data and sending it but has not received anything to decrypt in return. Therefore, we have a hard requirement that Cisco ASAs are only compatible with static gateways (or policy based). A vulnerability in the implementation of Traffic Flow Confidentiality (TFC) over IPsec functionality in Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS.
