CVE-2024-46665Network attack vector

RADIUS shared-secret disclosure via accounting requests

Published Jan 14, 2025 · Updated Jan 14, 2025

Information disclosure in Fortinet FortiOS 7.4.0 through 7.4.4 and 7.6.0 allows man-in-the-middle attackers to obtain a RADIUS secret. RADIUS accounting requests transmit the configured accounting-server shared secret in network data that an on-path attacker can intercept. Exploitation requires enabled RADIUS accounting and a position between the FortiGate and accounting server; the reported consequence is disclosure of that secret.
