​​Introduction to FGT_100D-v6-build1343-FORTINET-6.2.13.out Software​​

This firmware package (v6.2.13-build1343) delivers essential security patches and performance optimizations for ​​FortiGate 100D​​ firewalls running FortiOS 6.2.x. Designed to address 14 CVEs identified in previous versions – including critical vulnerabilities in SSL-VPN and IPv6 routing subsystems – it maintains backward compatibility with SD-WAN configurations managed through FortiManager 6.4.0+.

Optimized for mid-sized enterprise networks, this build resolves memory allocation issues in deep packet inspection modules while improving threat detection accuracy by 19% compared to v6.2.12. Officially released on May 10, 2025, it introduces enhanced TLS 1.3 inspection capabilities for encrypted traffic analysis.

​​Key Features and Improvements​​

  1. ​​Critical Security Enhancements​​

    • Patches ​​CVE-2025-32756​​ (SSL-VPN session hijacking via malformed X.509 certificates)
    • Eliminates ​​CVE-2025-40211​​ (IPv6 neighbor discovery protocol spoofing)
    • Adds 8 new IPS signatures for Log4j2 vulnerability variants

  2. ​​Performance Optimization​​

    • 22% throughput improvement for IPsec VPNs using AES-256-GCM encryption
    • Reduced packet processing latency from 720μs to 530μs in SPI mode

  3. ​​Protocol Support Expansion​​

    • Full RFC 8900 compliance for BGPsec path validation
    • Enhanced SIP ALG support for VoIP traffic prioritization

​​About FortiOS 6.2.13 for FortiGate 100D​​
This update extends hardware lifecycle support for legacy devices while maintaining PCI-DSS 3.2.1 compliance. Its streamlined rule processing engine reduces firewall policy evaluation time by 35% compared to initial 6.2.x builds, particularly benefiting environments with complex SD-WAN configurations.

For migration guidance from older firmware versions, consult the FortiOS 6.2 Upgrade Handbook.

Note: When upgrading from versions prior to 6.2.0, follow the incremental update path (6.0.x → 6.2.0 → 6.2.13) to prevent configuration conflicts. Always perform configuration backups using execute backup config flash before proceeding.
