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: - использование команд конфигурации для запрета выполнения перезагрузки при сбое диагностического теста (не рекомендуется применять для выпусков ПО Cisco NX-OS, которые не включают исправление Field Notice FN72433): nxos# configure nxos(config)# event manager applet l2acl_override override __L2ACLRedirect nxos(config-applet)# action 1 syslog priority emergencies msg l2aclFailed; - использование SIEM-систем для отслеживания событий, связанных с перезагрузкой устройства; - использование средств межсетевого экранирования для ограничения возможности попыток эксплуатации уязвимости.

CVE-2025-20111 (GCVE-0-2025-20111)

Vulnerability from cvelistv5 – Published: 2025-02-26 16:11 – Updated: 2025-02-26 18:03

Title

Cisco Nexus 3000 and 9000 Series Switches Layer 2 Ethernet Denial of Service Vulnerability

Summary

A vulnerability in the health monitoring diagnostics of Cisco Nexus 3000 Series Switches and Cisco Nexus 9000 Series Switches in standalone NX-OS mode could allow an unauthenticated, adjacent attacker to cause the device to reload unexpectedly, resulting in a denial of service (DoS) condition. This vulnerability is due to the incorrect handling of specific Ethernet frames. An attacker could exploit this vulnerability by sending a sustained rate of crafted Ethernet frames to an affected device. A successful exploit could allow the attacker to cause the device to reload.

Severity

Detection rules are retrieved from Rulezet.

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.
