CVE-2024-46666Network attack vector

GUI denial of service via endpoint resource exhaustion

Published Jan 14, 2025 · Updated Feb 18, 2025

Resource exhaustion in Fortinet FortiOS allows remote attackers to prevent GUI access through crafted requests to specific endpoints. Fortinet identifies unbounded resource allocation at those endpoints but has not disclosed their paths or the resource-consuming operation. Affected releases are 6.4.0 through 6.4.15, 7.0.0 through 7.0.16, 7.2.0 through 7.2.10, 7.4.0 through 7.4.4, and 7.6.0; no authentication is required.
