Name of the Vulnerable Software and Affected Versions Cisco Firepower Threat Defense (FTD) Software (affected versions not specified)

Description A vulnerability in the TCP ingress handler could allow an unauthenticated, remote attacker to cause an increase in CPU and memory usage, resulting in a denial of service (DoS) condition. The issue is due to insufficient ingress TCP rate limiting for TCP ports 22 (SSH) and 443 (HTTPS). An attacker could exploit this by sending a crafted, steady stream of TCP traffic to port 22 or 443 on the data interfaces configured with management access to the affected device.
