CVE-2020-3162 (CNNVD-202004-1101)
中文标题:
Cisco IoT Field Network Director Constrained Application Protocol 输入验证错误漏洞
英文标题:
Cisco IoT Field Network Director Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco IoT Field Network Director（IoT-FND）是美国思科（Cisco）公司的一套端到端的物联网管理系统。该系统具有设备管理、资产跟踪和智能计量等功能。 Cisco IoT Field Network Director中Constrained Application Protocol的实现中存在输入验证错误漏洞，该漏洞源于程序没有对传入CoAP流量进行充分地输入验证。攻击者可借助特制的CoAP数据包利用该漏洞迫使CoAP服务器停止，从而中断与IoT端点的通信。
英文描述:
A vulnerability in the Constrained Application Protocol (CoAP) implementation of Cisco IoT Field Network Director could allow an unauthenticated remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation of incoming CoAP traffic. An attacker could exploit this vulnerability by sending a malformed CoAP packet to an affected device. A successful exploit could allow the attacker to force the CoAP server to stop, interrupting communication to the IoT endpoints.
