Mitigations

Установка обновлений из доверенных источников. В связи со сложившейся обстановкой и введенными санкциями против Российской Федерации рекомендуется устанавливать обновления программного обеспечения только после оценки всех сопутствующих рисков. Компенсирующие меры: - отключение функционала отслеживания DHCP и анализа конечных точек; - использование средств межсетевого экранирования уровня веб-приложений для ограничения возможности удалённого доступа; - ограничение доступа из общедоступных сетей (Интернет); - использование виртуальных частных сетей для организации удаленного доступа (VPN).

CVE-2024-20259 (GCVE-0-2024-20259)

Vulnerability from cvelistv5 – Published: 2024-03-27 16:53 – Updated: 2024-08-27 21:04

Summary

A vulnerability in the DHCP snooping feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to a crafted IPv4 DHCP request packet being mishandled when endpoint analytics are enabled. An attacker could exploit this vulnerability by sending a crafted DHCP request through an affected device. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Note: The attack vector is listed as network because a DHCP relay anywhere on the network could allow exploits from networks other than the adjacent one.
