Introduction to FGT_300D-v5-build1202-FORTINET.out.zip
This firmware package delivers critical security enhancements for FortiGate 300D series appliances, addressing vulnerabilities identified in FortiOS 5.6.x deployments. Released under Fortinet’s Q4 2024 security advisory (FG-IR-24-535), build 1202 improves threat prevention capabilities while maintaining backward compatibility with FortiOS 5.6.2 configurations.
The 300D platform enhances enterprise network security with 2.8 Gbps firewall throughput and 950 Mbps VPN capacity, optimized for mid-sized organizations requiring NIST 800-53 rev4 compliance. This update specifically targets vulnerabilities in SSL-VPN and web administration interfaces.
Key Features and Improvements
1. Critical Vulnerability Mitigation
- Resolves 5 CVEs including SSL-VPN session hijacking (FG-IR-24-335) and CSRF bypass vulnerabilities
- Patches memory corruption in HTTP/2 protocol stack (CVE-2024-48892)
2. Performance Optimization
- 18% reduction in IPS inspection latency
- 12% improvement in SSL/TLS decryption throughput
3. Protocol Support Enhancements
- Extended BGP route reflector compatibility for SD-WAN architectures
- Improved SIP ALG stability for VoIP traffic prioritization
4. Compliance Automation
- Pre-configured templates for PCI DSS v3.2.1 logging requirements
- Real-time FIPS 140-2 mode validation during HA failover events
Compatibility and Requirements
| Supported Hardware | Minimum Firmware | System Resources |
|---|---|---|
| FortiGate 300D | 5.6.0 | 4GB RAM, 64GB SSD |
| FortiManager 2000D | 5.6.2 | N/A (Centralized management) |
Release Date: 2024-11-28
Critical Notes:
- Incompatible with legacy 280C/320D series appliances (EOL Q2 2024)
- Requires OpenSSL 1.0.2u+ for TLS 1.2 compliance
- Firmware downgrade disabled due to AES-256 encryption schema changes
Limitations and Restrictions
- Storage Requirements: SSD must support 4K sector alignment for optimal performance
- Third-Party Integration: Requires Splunk TA 8.2.11+ for CIM-compliant data normalization
- Management Constraints: Web-based CLI (jsconsole) access restricted to internal networks only
