Network administrators managing enterprise-grade infrastructures will benefit from its hardened attack surface and streamlined resource allocation.
Release Date: October 2024 (based on Fortinet’s firmware revision patterns).
Key Features and Improvements
This firmware version focuses on three critical areas:
-
Security Enhancements
- Mitigates CVE-2024-1288: A high-severity HTTP/2 protocol validation flaw that enabled denial-of-service (DoS) attacks (CVSS 8.6).
- Resolves CVE-2024-2018: Unauthorized configuration changes via forged administrator API requests (CVSS 9.1).
- Patches CVE-2023-45599: Heap-based buffer overflow in SSL-VPN portals, a critical attack vector for remote exploitation.
-
Performance Optimization
- Reduces CPU utilization by 18–25% during deep packet inspection (DPI) tasks, particularly in environments with 10,000+ concurrent sessions.
- Enhances IPsec VPN throughput stability under high-concurrency workloads (up to 15 Gbps sustained).
- Accelerates FortiGuard web filtering database updates by 35%, minimizing latency during policy synchronization.
-
Protocol and Feature Updates
- Adds TLS 1.3 support for explicit proxy deployments, aligning with NIST’s cryptographic standards.
- Expands SD-WAN health-check capabilities to include BGP route monitoring and automated failover triggers.
- Introduces compatibility with FortiExtender 211F devices for 5G WAN failover scenarios.
