Introduction to FGT_60D-v5-build1672-FORTINET.out
FGT_60D-v5-build1672-FORTINET.out is a critical firmware update for the FortiGate 60D Next-Generation Firewall, designed to address security vulnerabilities and optimize performance for small-to-medium enterprises (SMEs). This build (1672) belongs to FortiOS 5.6.8, a stable release targeting legacy hardware deployments requiring extended security support.
Compatible exclusively with the FortiGate 60D series, this firmware enhances threat prevention capabilities while maintaining compatibility with dual-WAN configurations and basic SD-WAN functionalities. Though official release dates are not publicly documented, build metadata suggests deployment in Q3 2017 as part of Fortinet’s extended support cycle for 5.x firmware.
Key Features and Improvements
1. Security Vulnerability Mitigation
- CVE-2024-55591 Remediation: Patched an authentication bypass vulnerability in Node.js websocket APIs that allowed privilege escalation to super_admin roles.
- SSL-VPN Hardening: Resolved credential leakage risks in SAML/SSO configurations through improved input validation.
2. Performance Optimizations
- 35% Faster IPsec VPN Throughput: Enhanced AES-256-CBC hardware acceleration for 50+ concurrent tunnels.
- Memory Efficiency: Reduced RAM consumption by 15% in deployments with 5,000+ concurrent sessions.
3. Protocol Support
- Extended TLS 1.2 inspection compatibility for legacy healthcare and financial systems.
- Added SD-WAN path monitoring for basic QoS prioritization of VoIP traffic.
4. Hardware Integration
- Optimized NP4 security processor utilization for 70 Mbps UTM throughput.
- Improved compatibility with 3G/4G USB modems for failover scenarios.
Compatibility and Requirements
Supported Hardware
| Model | Minimum OS | Hardware Specs |
|---|---|---|
| FortiGate 60D | FortiOS 5.4.0 | 2 GB RAM / 32 GB SSD |
| FortiGate 60D-POE | FortiOS 5.4.3 | 4 GB RAM for full logging |
System Requirements
- Memory: 2 GB DDR3 (4 GB recommended for IPS/AV inspection).
- Storage: 32 GB SSD for configuration backups and logs.
- Management: Compatible with FortiManager 5.6+ for centralized policy orchestration.
Incompatibility Notes
- Downgrading to FortiOS 4.x requires factory reset due to partition schema changes.
- Not supported on FortiGate 60E/61F series due to NP4 vs NP6 chipset differences.
Limitations and Restrictions
- Legacy Protocol Support: Excludes TLS 1.3 inspection and QUIC protocol analysis.
- Resource Constraints: Enabling “Full UTM Logging” reduces maximum throughput by 20%.
- Cloud Integration: No native support for SD-WAN orchestration with FortiManager 7.x+.
