What is CVE-2024-0218?

A Denial of Service vulnerability exists within Nozomi Networks Guardian, specifically linked to improper input validation in the RADIUS parsing functionality of the Intrusion Detection System (IDS). This vulnerability allows an unauthenticated attacker to send specially crafted malformed network packets, ultimately causing the IDS module to cease its operations in updating nodes, links, and assets. As a result, network traffic analysis will be interrupted and may persist until the affected IDS module is manually restarted.
