Title

Cisco IoT Field Network Director拒绝服务漏洞（CNVD-2020-34943）

Description

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的实现中存在拒绝服务漏洞，该漏洞源于程序未能对传入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。

Vulnerability from cvelistv5 – Published: 2020-04-15 20:10 – Updated: 2024-11-15 17:31

Title

Cisco IoT Field Network Director Denial of Service Vulnerability

Summary

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.

Severity

7.5 (High)
