​​Introduction to FGT_100EF-v6-build0457-FORTINET.out Software​​

This firmware package provides critical security patches and operational enhancements for ​​FortiGate 100EF Next-Generation Firewalls​​, part of Fortinet’s enterprise-class network security series. Designed for mid-sized networks requiring advanced threat prevention, build 0457 (based on FortiOS 6.0.14) addresses vulnerabilities while optimizing performance for SD-WAN and VPN services.

The release aligns with Fortinet’s Q4 2024 security advisory cycle, focusing on ​​CVE remediation​​ and ​​NP6 processor optimization​​ for the 100EF hardware platform. Exclusively compatible with FortiGate 100EF appliances, this version ensures backward compatibility with FortiManager 7.2+ centralized management systems.

​​Key Features and Improvements​​

  • Fixes ​​CVE-2024-48887​​ (CVSS 9.3): Unauthorized administrative access via GUI password reset.

2. ​​Performance Optimization​​

  • 22% throughput increase for IPsec VPN tunnels using NP6 network processors.
  • Reduced memory consumption in multi-VDOM configurations by 15%.

3. ​​Protocol & Management Enhancements​​

  • Adds TLS 1.3 session resumption support for Microsoft Azure/O365 traffic.
  • Improves FortiAnalyzer log synchronization stability in HA cluster deployments.

4. ​​IoT Security Updates​​
