漏洞描述
中文描述:
Cisco NX-OS Software等都是美国思科(Cisco)公司的产品。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 Nexus 3000 Series Switches是一款3000系列交换机。Cisco Nexus 9000 Series Switches是一款9000系列交换机。 Cisco 多款产品存在安全漏洞,该漏洞源于IS-IS协议存在安全漏洞。攻击者可利用该漏洞通过发送IS-IS数据包来导致系统拒绝服务(DoS)。以下产品及版本受到影响:Cisco NX-OS Software,Cisco Nexus 3000 Series Switches,Cisco Nexus 9000 Series Switches。
英文描述:
A vulnerability in the Intermediate System-to-Intermediate System (IS-IS) protocol of Cisco NX-OS Software for the Cisco Nexus 3000 Series Switches and Cisco Nexus 9000 Series Switches in standalone NX-OS mode could allow an unauthenticated, adjacent attacker to cause the IS-IS process to unexpectedly restart, which could cause an affected device to reload. This vulnerability is due to insufficient input validation when parsing an ingress IS-IS packet. An attacker could exploit this vulnerability by sending a crafted IS-IS packet to an affected device. A successful exploit could allow the attacker to cause a denial of service (DoS) condition due to the unexpected restart of the IS-IS process, which could cause the affected device to reload. Note: The IS-IS protocol is a routing protocol. To exploit this vulnerability, an attacker must be Layer 2 adjacent to the affected device.
