Title

Cisco Nexus 5600和6000系列交换机拒绝服务漏洞

Description

Cisco Nexus 5600和6000系列交换机是专为数据中心设计的模块化和固定端口网络交换机。 Cisco Nexus 5600和6000系列交换机的Cisco NX-OS软件的以太网光纤通道（FCoE）协议实现存在拒绝服务漏洞。该漏洞源于内部接口索引未能正确分配。能够提交跨受影响接口的特制FCoE数据包的近邻攻击者可利用漏洞导致受影响接口上的数据包循环和高吞吐量，从而可导致拒绝服务。

Title

Cisco Nexus 5600 and 6000 Series Switches Fibre Channel over Ethernet Denial of Service Vulnerability

Summary

A vulnerability in the Fibre Channel over Ethernet (FCoE) protocol implementation in Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to an incorrect allocation of an internal interface index. An adjacent attacker with the ability to submit a crafted FCoE packet that crosses affected interfaces could trigger this vulnerability. A successful exploit could allow the attacker to cause a packet loop and high throughput on the affected interfaces, resulting in a DoS condition. This vulnerability has been fixed in version 7.3(5)N1(1).

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.
