Vulnerability from cvelistv5 – Published: 2020-10-21 18:36 – Updated: 2024-11-13 17:47

Title

Cisco Firepower Threat Defense Software SSL Input Validation Denial of Service Vulnerability

Summary

A vulnerability in the ssl_inspection component of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to crash Snort instances. The vulnerability is due to insufficient input validation in the ssl_inspection component. An attacker could exploit this vulnerability by sending a malformed TLS packet through a Cisco Adaptive Security Appliance (ASA). A successful exploit could allow the attacker to crash a Snort instance, resulting in a denial of service (DoS) condition.
