漏洞描述
中文描述:

Cisco Nexus 3000 Series Switches等都是美国思科（Cisco）公司的产品。Cisco Nexus 3000 Series Switches是一款3000系列交换机。Cisco Nexus 3500 Platform Switches是一款3500系列平台交换机。Cisco MDS 9000 Series Multilayer Switches是一款MDS 9000系列多层交换机。Cisco NX-OS Software是一套交换机使用的数据中心级操作系统软件。 Cisco NX-OS Software中的Virtual Shell会话管理存在资源管理错误漏洞，该漏洞源于程序没有正确地删除VSH进程。远程攻击者可通过进行远程管理连接并不正当的断开连接利用该漏洞造成拒绝服务。以下产品及版本受到影响：Cisco MDS 9000 Series Multilayer Switches；Nexus 3000 Series Switches；Nexus 3500 Platform Switches；Nexus 3600 Platform Switches；Nexus 5500 Platform Switches；Nexus 5600 Platform Switches；Nexus 6000 Series Switches；Nexus 7000 Series Switches；Nexus 7700 Series Switches；Nexus 9000 Series Switches（standalone NX-OS mode）；Nexus 9500 R-Series Switching Platform；UCS 6200 Series Fabric Interconnects；UCS 6300 Series Fabric Interconnects。

英文描述:

A vulnerability in the Virtual Shell (VSH) session management for Cisco NX-OS Software could allow an authenticated, remote attacker to cause a VSH process to fail to delete upon termination. This can lead to a build-up of VSH processes that overtime can deplete system memory. When there is no system memory available, this can cause unexpected system behaviors and crashes. The vulnerability is due to the VSH process not being properly deleted when a remote management connection to the device is disconnected. An attacker could exploit this vulnerability by repeatedly performing a remote management connection to the device and terminating the connection in an unexpected manner. A successful exploit could allow the attacker to cause the VSH processes to fail to delete, which can lead to a system-wide denial of service (DoS) condition. The attacker must have valid user credentials to log in to the device using the remote management connection.
