Title: 多款Cisco产品输入验证错误漏洞（CNVD-2020-31966）

Description:

Cisco NX-OS Software等都是美国思科（Cisco）公司的产品。Cisco NX-OS Software是一套交换机使用的数据中心级操作系统软件。Cisco IOS是一套为其网络设备开发的操作系统。IOS XE是一套为其网络设备开发的操作系统。

多款Cisco产品中的One Platform Kit（onePK）的Topology Discovery Service存在输入验证错误漏洞，该漏洞源于在Topology Discovery Service解析Discovery Protocol协议消息时，程序未能充分验证长度。攻击者可通过发送恶意的Cisco Discovery Protocol消息利用该漏洞造成进程崩溃，导致设备重新加载及拒绝服务。

8.8 (High) - CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-20

Summary

A vulnerability in the Topology Discovery Service of Cisco One Platform Kit (onePK) in Cisco IOS Software, Cisco IOS XE Software, Cisco IOS XR Software, and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to execute arbitrary code or cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient length restrictions when the onePK Topology Discovery Service parses Cisco Discovery Protocol messages. An attacker could exploit this vulnerability by sending a malicious Cisco Discovery Protocol message to an affected device. An exploit could allow the attacker to cause a stack overflow, which could allow the attacker to execute arbitrary code with administrative privileges, or to cause a process crash, which could result in a reload of the device and cause a DoS condition.
