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 中存在输入验证错误漏洞,该漏洞源于产品 VXLAN Operation、Administration、 Maintenance 功能的 TRILL (Transparent Interconnection of Lots of Links) OAM 未对输入数据包处理不当,攻击者可通过该漏洞导致拒绝服务。

英文描述:

A vulnerability in the VXLAN Operation, Administration, and Maintenance (OAM) feature of Cisco NX-OS Software, known as NGOAM, could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of specific packets with a Transparent Interconnection of Lots of Links (TRILL) OAM EtherType. An attacker could exploit this vulnerability by sending crafted packets, including the TRILL OAM EtherType of 0x8902, to a device that is part of a VXLAN Ethernet VPN (EVPN) fabric. A successful exploit could allow the attacker to cause an affected device to experience high CPU usage and consume excessive system resources, which may result in overall control plane instability and cause the affected device to reload. Note: The NGOAM feature is disabled by default.
