Title

Cisco Nexus 1000v Application Virtual Switch拒绝服务漏洞

Description

Cisco Nexus 1000v Application Virtual Switch（AVS）是美国思科（Cisco）公司的一套专为虚拟机开发的虚拟交换机软件。该软件用来取代Vmware内置的分布式虚拟交换机，并包含了管理程序内部运行的虚拟以太网模块（VEM）和管理VEM的外部虚拟控制引擎模块（VSM）两个组件。 Cisco Nexus 1000v AVS设备5.2(1)SV3(1.5i)之前的版本中存在安全漏洞。远程攻击者可借助Cisco Discovery Protocol数据包利用该漏洞造成拒绝服务（ESXi管理程序崩溃和蓝屏）。
