Introduction to FGT_300D-v6-build1319-FORTINET.out.zip

This firmware package (build 1319) delivers FortiOS 6.0.6 for FortiGate 300D next-generation firewalls, addressing critical network vulnerabilities while optimizing threat inspection throughput. Designed for mid-sized enterprise deployments, it maintains compatibility with existing 5.6.x configurations while introducing next-generation security protocols.

The software exclusively supports FortiGate 300D hardware (FG-300D) – a 1U rack-mounted appliance with 16 Gbps firewall capacity and 8 Gbps IPSec VPN performance. Originally released through Fortinet’s partner portal in Q3 2024, this build implements NIST-recommended cryptographic standards for federal compliance workflows.

  • Patches 9 CVEs including ​​CVE-2024-48887​​ (CVSS 9.1): Unauthorized administrative access via HTTP/HTTPS request smuggling
  • Implements FIPS 140-3 Level 2 validation for government/military networks

​​2. Performance Enhancements​​

  • Boosts IPSec throughput by 22% through NP6 ASIC optimization
  • Reduces memory consumption in SSL inspection workflows by 38% vs 6.0.5

​​3. Protocol Modernization​​

  • Supports RFC 9293 for improved TCP error handling
  • Adds QUIC protocol visibility across 23 SaaS applications

​​4. Management Upgrades​​

  • Introduces REST API v2.2 for bulk policy deployments
