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Cisco Fabric Services组件存在输入验证错误漏洞，该漏洞源于程序没有充分验证TCP数据包。远程攻击者可通过发送恶意的Cisco Fabric Services TCP数据包利用该漏洞造成拒绝服务（进程崩溃）。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 Cisco Fabric Services component of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause process crashes, which can result in a denial of service (DoS) condition on an affected system. The vulnerability is due to insufficient validation of TCP packets when processed by the Cisco Fabric Services over IP (CFSoIP) feature. An attacker could exploit this vulnerability by sending a malicious Cisco Fabric Services TCP packet to an affected device. A successful exploit could allow the attacker to cause process crashes, resulting in a device reload and a DoS condition. Note: There are three distribution methods that can be configured for Cisco Fabric Services. This vulnerability affects only distribution method CFSoIP, which is disabled by default. See the Details section for more information.
