Introduction to FGT_200D-v6-build0335-FORTINET.out Software
This critical firmware update addresses multiple high-priority vulnerabilities in FortiGate 200D series next-generation firewalls, designed for enterprise branch networks requiring advanced threat prevention capabilities. Released on March 11, 2025, the build0335 version resolves SSL-VPN security flaws while optimizing network performance for environments handling encrypted financial transactions and IoT device management.
Specifically engineered for the FG-200D hardware platform, this update enhances hardware-accelerated security processing through integrated CP8 ASIC chips. It supports compliance frameworks including PCI-DSS 4.0 and NIST 800-53 through improved traffic inspection capabilities for high-volume network segments.
Key Features and Improvements
Critical Security Updates
- Mitigation of CVE-2024-21762 (CVSS 9.8): Remote code execution vulnerability in SSL-VPN portal via HTTP chunk encoding exploit
- Enhanced certificate validation for SD-WAN IPsec tunnels preventing downgrade attacks
- 68 new zero-day threat signatures added to FortiGuard IPS database
Network Performance Optimization
- 25% throughput increase for AES-GCM encrypted traffic on 10GbE interfaces
- Non-blocking memory architecture reduces policy processing latency by 35%
- Dynamic load balancing for BGP routing tables with 500k+ entries
Operational Enhancements
- REST API v2.6 compatibility with Ansible Tower automation workflows
- Cross-VDOM threat intelligence sharing via Security Fabric overlay
- Real-time traffic visualization in FortiView topology maps
Compatibility and Requirements
| Component | Specification |
|---|---|
| Hardware Platform | FortiGate 200D (FG-200D) |
| FortiOS Version | 6.0.18 (Build 0335) |
| Minimum RAM | 8GB DDR4 ECC |
| Storage Requirement | 128GB SSD free capacity |
| Network Interfaces | 10GbE SFP+, 1GbE RJ45 |
This firmware maintains interoperability with FortiSwitch 224D-POE and FortiAP 231F access points. Third-party RADIUS servers require TLS 1.3 encryption for authentication services.
Limitations and Restrictions
- Maximum concurrent SSL-VPN users capped at 200 (hardware limitation)
- No backward compatibility with FortiClient 5.6.x endpoint agents
- Custom IPS sensor configurations require manual migration
- Firmware rollback to versions prior to 6.0.15 disables hardware acceleration
