Introduction to FGT_60D-v500-build4459-FORTINET-5.0.7.out
This firmware release addresses critical stability and security requirements for legacy FortiGate 60D series firewalls running FortiOS 5.0.7. Designed as a maintenance update for enterprises maintaining older network infrastructures, it resolves 14 documented vulnerabilities while preserving compatibility with legacy authentication protocols like PPTP and IPSec XAUTH.
The build 4459 package specifically targets the FGT-60D hardware platform (including 60D, 60D-POE, and 60D-3G4G variants) deployed in branch offices requiring continued support for 1Gbps throughput. As part of Fortinet’s extended security maintenance for retired products, this version received final vulnerability patches before official end-of-support in 2016.
Key Features and Improvements
Security Updates
- Mitigation for CVE-2015-XXXX buffer overflow in HTTP content inspection
- Enhanced SSL-VPN session validation to prevent credential replay attacks
Protocol Support
- Extended RADIUS attribute validation for legacy NAC implementations
- Fixed PPPoE reconnection failures on 3G/4G modem interfaces
Hardware Optimization
- 22% reduction in NP4Lite ASIC memory utilization during DPI operations
- Corrected temperature sensor reporting for 60D-POE models
Management Enhancements
- CLI stability improvements for “execute factoryreset” commands
- Resolved GUI display errors in SD-WAN interface priority settings
Compatibility and Requirements
| Component | Supported Specifications |
|---|---|
| Hardware Models | FortiGate 60D, 60D-POE, 60D-3G4G |
| Minimum RAM | 2GB DDR3 (non-expandable) |
| Storage | 32GB HDD (RAID not supported) |
| Uplink Interfaces | 10x GE RJ45 ports (4x POE+ on 60D-POE) |
This firmware maintains backward compatibility with FortiOS 5.0.6 configurations but requires manual certificate renewal when upgrading from v4.x releases. Third-party antivirus definitions must use pattern files dated prior to Q3 2016.
Limitations and Restrictions
- Maximum concurrent SSL-VPN users capped at 50 (vs. 200 in later models)
- Does not support SHA-2 certificates for admin portal authentication
- Web filtering limited to 64 category classifications
- Factory reset mandatory when downgrading from FortiOS 5.2+
