TITLE

Cisco IoT Field Network Director Resource Management Error Vulnerability

Trust: 1.2

sources: CNVD: CNVD-2020-12743 // CNNVD: CNNVD-201901-858

DESCRIPTION

A vulnerability in the UDP protocol implementation for Cisco IoT Field Network Director (IoT-FND) could allow an unauthenticated, remote attacker to exhaust system resources, resulting in a denial of service (DoS) condition. The vulnerability is due to improper resource management for UDP ingress packets. An attacker could exploit this vulnerability by sending a high rate of UDP packets to an affected system within a short period of time. A successful exploit could allow the attacker to exhaust available system resources, resulting in a DoS condition. The system has functions such as equipment management, asset tracking and intelligent metering. There are security holes in the implementation of the UDP protocol in Cisco IoT-FND. This issue is being tracked by Cisco bug ID CSCvj35124
