Mitigations

Компенсирующие меры: - отслеживание DHCP-трафика - активация функций ARP-защиты - ограничение доступа к DHCP-серверу доверенными IP-адресами - отключение опции 121 «Бесклассовые статические маршруты» для DHCP-сервера при использовании в сети VPN ( конкретная команда или последовательность действий зависят от операционной системы и модели применяемого оборудования); использование средств межсетевого экранирования для ограничения возможности удалённого доступа к устройствам; - использование систем обнаружения и предотвращения вторжений для контроля попыток подключения к устройствам. Для МСВСфера: https://errata.msvsphere-os.ru/definition/9/INFCESA-2025:0006?lang=ru

Credits

Атака может быть осуществлена в любых операционных системах, поддерживающих 121 опцию DHCP, включая Linux, Windows, iOS и macOS, независимо от используемого протокола VPN.

CVE-2024-3661 (GCVE-0-2024-3661)

Vulnerability from cvelistv5 – Published: 2024-05-06 18:31 – Updated: 2024-08-28 19:09

Title

DHCP routing options can manipulate interface-based VPN traffic

Summary

DHCP can add routes to a client’s routing table via the classless static route option (121). VPN-based security solutions that rely on routes to redirect traffic can be forced to leak traffic over the physical interface. An attacker on the same local network can read, disrupt, or possibly modify network traffic that was expected to be protected by the VPN.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
