CVE-2019-1644: Cisco IoT Field Network Director Resource Exhaustion Denial of Service Vulnerability

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.

Security readout for executives and security teams

CVE-2019-1644 can let an unauthenticated remote attacker knock Cisco IoT Field Network Director offline by overwhelming it with UDP traffic. The business impact is availability: systems depending on IoT-FND management functions may become unavailable. The source bundle does not name affected versions or a specific fix. Exposure is limited to environments running Cisco IoT Field Network Director. Risk is higher where the affected system can receive UDP traffic from untrusted networks. The supplied data lists versions as n/a, so asset owners must verify scope against Cisco guidance. Prioritize if Cisco IoT-FND supports operational or field-network management functions, especially if reachable from broad networks. The main risk is service disruption, not data theft. Because affected versions and fixes are not included in the bundle, confirmation against Cisco guidance is the immediate decision point. Mitigation focus: Identify all Cisco IoT-FND deployments and owners.; Review Cisco advisory guidance for affected and fixed releases.; Restrict UDP reachability to trusted management networks where operationally possible..
