Possible 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. Функция OSPFv3 отключена по умолчанию. Чтобы определить, включена ли данная функция на устройстве, используйте команду: show feature | include ospfv3 или: show running-config | include "ipv6 router ospfv3" Чтобы определить, есть ли у устройства смежные узлы с включенной функцией OSPFv3 в состоянии FULL, используйте команду: show ipv6 ospfv3 neighbors Компенсирующие меры: - включение функции аутентификации OSPFv3 на уязвимых коммутаторах; - использование межсетевого экрана уровня приложений; - использование системы обнаружения и предотвращения вторжений.

CVE-2022-20823 (GCVE-0-2022-20823)

Title

Cisco NX-OS Software OSPFv3 Denial of Service Vulnerability

Summary

A vulnerability in the OSPF version 3 (OSPFv3) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to incomplete input validation of specific OSPFv3 packets. An attacker could exploit this vulnerability by sending a malicious OSPFv3 link-state advertisement (LSA) to an affected device. A successful exploit could allow the attacker to cause the OSPFv3 process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition. Note: The OSPFv3 feature is disabled by default. To exploit this vulnerability, an attacker must be able to establish a full OSPFv3 neighbor state with an affected device. For more information about exploitation conditions, see the Details section of this advisory.

This vulnerability is due to incomplete input validation of specific OSPFv3 packets. An attacker could exploit this vulnerability by sending a malicious OSPFv3 link-state advertisement (LSA) to an affected device. A successful exploit could allow the attacker to cause the OSPFv3 process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition. Note: The OSPFv3 feature is disabled by default. To exploit this vulnerability, an attacker must be able to establish a full OSPFv3 neighbor state with an affected device.
