漏洞描述
中文描述:

Cisco Nexus 9000 Series Fabric Switches是美国思科(Cisco)公司的一款9000系列光纤交换机。 Cisco Nexus 9000 Series Switch Software(ACI Mode)13.2(7f)之前版本和14.x版本中的LLDP子系统存在缓冲区错误漏洞,该漏洞源于程序没有对LLDP帧头中TLV字段进行正确的输入验证。攻击者可通过发送特制的LLDP数据包利用该漏洞造成拒绝服务或以root权限执行任意代码。

英文描述:

A vulnerability in the Link Layer Discovery Protocol (LLDP) subsystem of Cisco Nexus 9000 Series Application Centric Infrastructure (ACI) Mode Switch Software could allow an adjacent, unauthenticated attacker to cause a denial of service (DoS) condition or execute arbitrary code with root privileges. The vulnerability is due to improper input validation of certain type, length, value (TLV) fields of the LLDP frame header. An attacker could exploit this vulnerability by sending a crafted LLDP packet to the targeted device. A successful exploit may lead to a buffer overflow condition that could either cause a DoS condition or allow the attacker to execute arbitrary code with root privileges. Note: This vulnerability cannot be exploited by transit traffic through the device; the crafted packet must be targeted to a directly connected interface. This vulnerability affects Cisco Nexus 9000 Series Fabric Switches in ACI mode if they are running a Cisco Nexus 9000 Series ACI Mode Switch Software release prior to 13.2(7f) or any 14.x release.
