CVE-2018-15462 is a high-severity vulnerability affecting cisco secure_firewall_threat_defense. It was published on May 3, 2019 and has a CVSS 3.0 base score of 8.6 (HIGH).
This vulnerability has a CVSS 3.0 base score of 8.6, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.
Technical Description
A vulnerability in the TCP ingress handler for the data interfaces that are configured with management access to Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause an increase in CPU and memory usage, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient ingress TCP rate limiting for TCP ports 22 (SSH) and 443 (HTTPS). An attacker could exploit this vulnerability by sending a crafted, steady stream of TCP traffic to port 22 or 443 on the data interfaces that are configured with management access to the affected device.
Remediation
Check the references section for vendor advisories and patches from cisco. Update secure_firewall_threat_defense to the latest patched version.
