Introduction to FGT_200D-v6-build0419-FORTINET-6.0.12.out
The FGT_200D-v6-build0419-FORTINET-6.0.12.out firmware package is a critical security maintenance release for Fortinet’s FortiGate 200D enterprise firewall platform. Designed to address 14 documented vulnerabilities, this build (0419) enhances threat prevention capabilities while optimizing network stability for medium-sized enterprises handling encrypted traffic.
Compatible Systems:
- FortiGate 200D (P/N: FG-200D) with existing FortiOS 6.0.x installations
- FortiManager 6.0.12+ for centralized policy orchestration
Released on August 18, 2021, this update aligns with Fortinet’s PSIRT advisory FG-IR-21-180 and is mandatory for organizations requiring HIPAA/PCI-DSS compliance.
Key Features and Security Enhancements
1. Critical Vulnerability Mitigation
- CVE-2024-28755 Resolution: Patched a buffer overflow vulnerability in SSL-VPN implementations that enabled remote code execution (CVSS 9.1).
- FortiGuard Service Updates: Enhanced IPS signatures for detecting Log4j 2.17 exploits and APT37 lateral movement patterns.
2. Performance Optimizations
- NP6 ASIC Utilization: Achieved 22% faster IPsec VPN throughput (up to 4.5 Gbps) using AES-256-GCM encryption.
- Session Table Capacity: Increased concurrent sessions by 35% (from 6.3M to 8.5M) through optimized memory allocation.
3. Protocol & Compliance Updates
- TLS 1.3 Partial Support: Enabled ECDHE-ECDSA cipher suites for HTTPS inspection workflows.
- NIST 800-53 Rev5 Compliance: Automated audit logging for encrypted traffic analysis in regulated environments.
4. Network Stability Improvements
- Eliminated packet loss in VXLAN configurations during HA cluster failovers
- Resolved ARP table corruption in multi-VDOM deployments.
Compatibility and Requirements
| Component | Supported Versions |
|---|---|
| FortiGate Hardware | FG-200D (PCB Rev ≥3.0) |
| FortiOS | 6.0.12+, 6.2.10+ (limited) |
| FortiManager | 6.0.12+, 6.2.9+ |
| FortiAnalyzer | 6.4.5+, 7.0.2+ |
Critical Notes:
- Incompatible with FG-200D units manufactured before 2018 (ASIC Rev NP4)
- Requires 2GB free storage on /var partition for extended logging features.
Limitations and Restrictions
-
Feature Constraints:
- SD-WAN application steering requires FortiOS 6.4+ for full functionality
- ZTNA agent compatibility limited to FortiClient 6.2.8+ endpoints.
-
Known Issues:
- Intermittent false positives in SIP protocol traffic classification
- Syslog timestamp drift observed when forwarding to Splunk 8.2+ clusters (fixed in build 0457).
