中文标题:
Cisco NX-OS Software 缓冲区错误漏洞
英文标题:
Cisco NX-OS Software Cisco Discovery Protocol Remote Code Execution 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Cisco Discovery Protocol的实现存在缓冲区错误漏洞，该漏洞源于程序没有正确地验证输入。攻击者可通过发送恶意的Cisco Discovery Protocol数据包利用该漏洞执行任意代码或重新加载受影响的设备。
英文描述:
A vulnerability in the Cisco Discovery Protocol implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a reload on an affected device. The vulnerability exists because the Cisco Discovery Protocol parser does not properly validate input for certain fields in a Cisco Discovery Protocol message. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol packet to an affected device. An successful exploit could allow the attacker to cause a stack overflow, which could allow the attacker to execute arbitrary code with administrative privileges on an affected device. Cisco Discovery Protocol is a Layer 2 protocol. To exploit this vulnerability, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).
