Detailsinfo

A vulnerability, which was classified as critical, was found in Cisco Firepower Threat Defense Software (Firewall Software). Affected is an unknown part of the component ICMPv6 Inspection Handler. The manipulation with an unknown input leads to a denial of service vulnerability. CWE is classifying the issue as CWE-404. The product does not release or incorrectly releases a resource before it is made available for re-use. This is going to have an impact on availability. CVE summarizes:

A vulnerability in ICMPv6 inspection when configured with the Snort 2 detection engine for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause the CPU of an affected device to spike to 100 percent, which could stop all traffic processing and result in a denial of service (DoS) condition. FTD management traffic is not affected by this vulnerability. This vulnerability is due to improper error checking when parsing fields within the ICMPv6 header. An attacker could exploit this vulnerability by sending a crafted ICMPv6 packet through an affected device. A successful exploit could allow the attacker to cause the device to exhaust CPU resources and stop processing traffic, resulting in a DoS condition. Note: To recover from the DoS condition, the Snort 2 Detection Engine or the Cisco FTD device may need to be restarted.

The weakness was shared 11/01/2023 as cisco-sa-ftd-icmpv6-dos-4eMkLuN. The advisory is available at sec.cloudapps.cisco.com. This vulnerability is traded as CVE-2023-20083 since 10/27/2022.
