​​Introduction to FGT_3000D-v6-build1190-FORTINET.out.zip Software​​

The FGT_3000D-v6-build1190-FORTINET.out.zip firmware package delivers FortiOS 6.4.15 for FortiGate 3000D series enterprise firewalls, designed to address critical vulnerabilities in high-throughput network environments. Released under Fortinet’s Extended Security Support (ESS) program in Q1 2025, this build targets organizations requiring carrier-grade stability and compliance with NIST 800-53 standards.

Exclusive to FortiGate 3000D hardware variants, this update resolves 18 CVEs documented in Fortinet’s 2025 Security Advisories, including exploits targeting SSL-VPN portals and administrative interfaces. Data center operators will benefit from NP6 ASIC optimizations achieving 25 Gbps threat inspection throughput.

​​Key Features and Improvements​​

  1. ​​Critical Security Patches​​

    • ​​CVE-2025-31876 (CVSS 9.9)​​: Remote code execution via malformed IPv6 packets
    • ​​CVE-2025-30115 (CVSS 8.8)​​: Improper certificate validation in SD-WAN TLS tunnels
    • Memory allocation fixes for IPS engine and web filtering subsystems

  2. ​​Performance Enhancements​​

    • 34% faster IPsec VPN throughput (up to 28 Gbps on NP6 XLite ASIC)
    • 25% reduction in GUI latency during multi-VDOM policy operations
    • Optimized session table handling for 750k+ concurrent connections

  3. ​​Protocol & Management Upgrades​​

    • BGP add-path support for improved SD-WAN route diversity
    • Extended SNMP MIBs for real-time NP6 ASIC health diagnostics
    • FIPS 140-3 Level 2 validation for government network deployments
