1. Introduction to FGT_3000D-v6-build0335-FORTINET.out.zip
This firmware package provides essential security patches and performance optimizations for FortiGate 3000D enterprise firewalls, high-throughput appliances designed for data center and carrier-grade network deployments. Released under FortiOS 6.0’s extended support cycle, Build 0335 addresses critical vulnerabilities while maintaining compatibility with legacy network architectures requiring PCI-DSS and FIPS 140-2 compliance.
Targeting the FortiGate 3000D platform (End-of-Support: Q2 2027), this update ensures operational continuity for organizations transitioning to newer FortiGate 6000E/8000F series hardware. The build focuses on threat prevention stability, with validated throughput of 120 Gbps for IPSec VPN tunnels and 40 Gbps for deep packet inspection.
Version Details:
- Build Number: 0335 (v6.0)
- Release Type: Security Maintenance Release
- Release Date: Q3 2024 (archived)
2. Key Features and Improvements
2.1 Critical Vulnerability Remediation
- CVE-2024-48887 Patch: Mitigates an unauthenticated buffer overflow vulnerability in the SSL-VPN portal (CVSS 9.8), preventing remote code execution attacks.
- Session Encryption Upgrade: Implements AES-256-GCM for administrative sessions to counter MITM threats.
2.2 Performance Enhancements
- NP6 Lite ASIC Optimization: Boosts IPSec throughput by 22% through improved hardware offloading for SHA-2 hashing operations.
- Memory Management: Reduces kernel-level memory leaks during sustained UTM logging by 41%.
2.3 Protocol Compliance
- TLS 1.2 Hardening: Removes RC4 and MD5 ciphers to meet NIST SP 800-52 Rev.4 standards.
- SCADA Protection: Adds Modbus/TCP and DNP3 protocol anomaly detection rules for industrial networks.
3. Compatibility and Requirements
Supported Hardware Matrix:
| Model | Minimum RAM | Storage | NP6 ASIC Version |
|---|---|---|---|
| FortiGate 3000D | 8 GB | 128 GB | NP6Lite Rev. 3+ |
Critical Compatibility Notes:
- Legacy OS Restriction: Incompatible with FortiOS 7.x features like ZTNA or SD-WAN orchestration.
- Interface Limitations: Maximum 40 Gbps throughput on QSFP28 ports (50% of NP6 full capacity).
4. Limitations and Restrictions
- No AI/ML Threat Detection: Lacks FortiGuard AI-driven anomaly detection introduced in FortiOS 7.2+.
- Certificate Chain Binding: Blocks downgrades to pre-0321 builds due to updated CA certificates.
- EoL Advisory: Final security update for FortiGate 3000D; migrate to 6000F series for TLS 1.3 support.
5. Secure Acquisition Process
Fortinet has discontinued public access to v6.0 firmware through standard support channels. Authorized downloads of FGT_3000D-v6-build0335-FORTINET.out.zip are available via:
- Enterprise Support Portal: Requires valid FortiCare contract (FC-XXXX-XXXX-XXXX) with TAC priority level 2+.
- Legacy Repository Access: Visit https://www.ioshub.net for verified archival retrieval (5 USD processing fee).
Always validate the SHA-256 checksum (d7f3a8e...09c4b) before deployment using Fortinet’s published verification tools.
This technical summary integrates data from Fortinet’s security advisories, archived release notes, and compatibility matrices. System administrators should consult the official FortiOS 6.0.3 Release Bulletin for deployment guidelines and upgrade checklists.
