CVE-2022-20767 (GCVE-0-2022-20767)

Vulnerability from cvelistv5 – Published: 2022-05-03 03:15 – Updated: 2024-11-06 16:20

Title

Cisco Firepower Threat Defense Software DNS Enforcement Denial of Service Vulnerability

Summary

A vulnerability in the Snort rule evaluation function of Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper handling of the DNS reputation enforcement rule. An attacker could exploit this vulnerability by sending crafted UDP packets through an affected device to force a buildup of UDP connections. A successful exploit could allow the attacker to cause traffic that is going through the affected device to be dropped, resulting in a DoS condition. Note: This vulnerability only affects Cisco FTD devices that are running Snort 3.

Severity
