Cisco NX-OS Software for Nexus 5500, 5600, and 6000 Series Switches Precision Time Protocol Denial of Service Vulnerability

Cisco Nexus 5500、5600和6000 Series交换机NX-OS Software 安全漏洞

面向Nexus 5500、5600和6000系列交换机的Cisco NX-OS软件Precision Time Protocol拒绝服务漏洞

A vulnerability in the Precision Time Protocol (PTP) feature of Cisco Nexus 5500, 5600, and 6000 Series Switches running Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of protection against PTP frame flood attacks. An attacker could exploit this vulnerability by sending large streams of malicious IPv4 or IPv6 PTP traffic to the affected device. A successful exploit could allow the attacker to cause a DoS condition, impacting the traffic passing through the device.

Cisco Nexus 5500、5600和6000 Series Switches都是美国思科（Cisco）公司的不同系列的交换机产品。NX-OS Software是运行在其中的一套交换机使用的数据中心级操作系统软件。 Cisco Nexus 5500、5600和6000 Series交换机中的NX-OS Software的Precision Time Protocol (PTP)功能存在安全漏洞。远程攻击者可通过向受影响的设备发送大量恶意的IPv4或IPv6 PTP流量利用该漏洞造成拒绝服务。
