漏洞描述
中文描述:
Cisco NX-OS Software是美国思科(Cisco)公司的一套交换机使用的数据中心级操作系统软件。 Cisco NX-OS Software 存在安全漏洞,攻击者利用该漏洞导致受影响设备拒绝服务。
英文描述:
A vulnerability in the MPLS Operation, Administration, and Maintenance (OAM) feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper input validation when an affected device is processing an MPLS echo-request or echo-reply packet. An attacker could exploit this vulnerability by sending malicious MPLS echo-request or echo-reply packets to an interface that is enabled for MPLS forwarding on the affected device. A successful exploit could allow the attacker to cause the MPLS OAM process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition.
