中文标题:
Cisco NX-OS Software 缓冲区错误漏洞
英文标题:
Cisco NX-OS Software Data Management Engine 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存在安全漏洞，该漏洞源于输入验证不足，攻击者可以利用该漏洞提升权限或者导致受影响设备拒绝服务。
英文描述:
A vulnerability in the Data Management Engine (DME) of Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code with administrative privileges or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation. An attacker could exploit this vulnerability by sending a crafted Cisco Discovery Protocol packet to a Layer 2-adjacent affected device. A successful exploit could allow the attacker to execute arbitrary code with administrative privileges or cause the Cisco Discovery Protocol process to crash and restart multiple times, causing the affected device to reload and resulting in a DoS condition. Note: 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). Exploitation of this vulnerability also requires jumbo frames to be enabled on the interface that receives the crafted Cisco Discovery Protocol packets on the affected device.
