CVE-2020-3174 (CNNVD-202002-1219)
中文标题:
Cisco NX-OS Software 数据伪造问题漏洞
英文标题:
Cisco NX-OS Software Anycast Gateway Invalid ARP Vulnerability
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中的选播网关功能存在数据伪造问题漏洞,该漏洞源于程序没有正确验证所接收的Address Resolution Protocol条目。攻击者可通过发送恶意的GARP数据包利用该漏洞造成ARP表单损坏。以下产品及版本受到影响:Nexus 3000 Series Switches;Nexus 7000 Series Switches;Nexus 9000 Series Switches(处于standalone NX-OS模式下)。
英文描述:
A vulnerability in the anycast gateway feature of Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a device to learn invalid Address Resolution Protocol (ARP) entries. The ARP entries are for nonlocal IP addresses for the subnet. The vulnerability is due to improper validation of a received gratuitous ARP (GARP) request. An attacker could exploit this vulnerability by sending a malicious GARP packet on the local subnet to cause the ARP table on the device to become corrupted. A successful exploit could allow the attacker to populate the ARP table with incorrect entries, which could lead to traffic disruptions.
