Cisco IOS XE Software Vulnerability Could Lead to Denial of Service

CVE-2024-20259

What is CVE-2024-20259?

A vulnerability exists in the DHCP snooping feature of Cisco IOS XE Software, allowing unauthenticated, remote attackers to exploit the flaw. This vulnerability occurs due to improper handling of crafted IPv4 DHCP request packets when endpoint analytics are enabled. Exploitation involves sending a specially crafted DHCP request, which can trigger an unexpected device reload, leading to a Denial of Service (DoS) condition. The attack vector can be exploited from a DHCP relay in different network segments, potentially expanding the scope of the vulnerability beyond adjacent networks.
