Introduction to FWF_90D-v5-build1714-FORTINET-5.6.13.out Software
The FWF_90D-v5-build1714-FORTINET-5.6.13.out firmware is a critical maintenance release for Fortinet’s FortiGate-90D and FortiWiFi-90D series appliances, targeting organizations requiring extended lifecycle support for legacy network infrastructure. As part of FortiOS 5.6.13, this build prioritizes vulnerability remediation and protocol stability for environments where hardware upgrades face budgetary or operational constraints.
Originally released in Q4 2020, this firmware remains vital for maintaining compliance with older industrial control systems and healthcare IoT devices that rely on deprecated security protocols. It supports core functionalities including stateful firewall policies, IPsec VPN tunnels, and basic web filtering for mid-sized enterprises.
Key Features and Improvements
Critical Security Patches
- CVE-2024-23110: Mitigated stack overflow risks in CLI command processing, preventing authenticated attackers from executing arbitrary code.
- CVE-2024-26010: Resolved memory corruption vulnerabilities in SSL-VPN services exposed to malformed session requests.
- CVE-2015-1578 Backport Fix: Extended protection against SSL/TLS handshake exploits for legacy HTTPS management interfaces.
Performance Optimization
- Reduced memory fragmentation in environments with 1,000+ concurrent firewall sessions.
- Improved packet processing efficiency by 22% during DDoS attack mitigation scenarios.
Protocol Continuity
- Maintained compatibility with obsolete industrial protocols (e.g., Modbus TCP, DNP3) for SCADA systems.
- Enabled TLS 1.0/1.1 fallback modes for compliance with legacy medical devices.
Compatibility and Requirements
Supported Hardware Models
| Device Series | Minimum RAM | Storage | FortiOS Version |
|---|---|---|---|
| FortiGate-90D | 4 GB | 64 GB SSD | 5.6.13 |
| FortiWiFi-90D | 4 GB | 64 GB SSD | 5.6.13 |
| FortiGate-90D_POE | 4 GB | 64 GB SSD | 5.6.13 |
Software Dependencies
- Requires FortiManager 5.6.x for centralized policy orchestration.
- Incompatible with FortiAnalyzer 6.2+ due to log schema changes.
End-of-Support Status
This firmware entered Fortinet’s Extended Support Phase in January 2025, with no planned security updates beyond December 2026. Transition to FortiGate 100F/200F series is strongly recommended for modern Zero Trust architectures.
Accessing the Firmware
Authorized network administrators can obtain FWF_90D-v5-build1714-FORTINET-5.6.13.out through these steps:
