CVE-2024-0218 is a high-severity vulnerability rated 8.2/10 on the CVSS scale. A Denial of Service (Dos) vulnerability in Nozomi Networks Guardian, caused by improper input validation in certain fields used in the Radius parsing functionality of our IDS, allows an unauthenticated attacker sending specially crafted malformed network packets to cause the IDS module to stop updating nodes, links, and assets. Network traffic may not be analyzed until the IDS module is restarted.. EPSS estimates a 0.55% chance of exploitation in the next 30 days.
