Introduction to FGT_80E-v6-build1579-FORTINET.out Software
This firmware release (build 1579) delivers critical security enhancements for FortiGate 80E next-generation firewalls operating on FortiOS 6.4.10. Designed for small-to-medium enterprises requiring robust network protection with cost-effective hardware utilization, this update resolves 12 documented vulnerabilities while optimizing threat detection capabilities for encrypted traffic inspection.
Specifically engineered for the 1U rack-mountable FortiGate 80E platform – supporting up to 5 Gbps firewall throughput and 700 Mbps IPSec VPN performance – this build was released in Q1 2025 as part of Fortinet’s quarterly security maintenance cycle. It prioritizes vulnerability remediation for publicly exposed management interfaces while maintaining backward compatibility with SD-WAN configurations.
Key Features and Improvements
Critical Security Updates
- CVE-2024-33502 Patch: Addresses high-risk path traversal vulnerabilities in SSL-VPN portals (CVSS 8.1) affecting configurations with SAML authentication.
- Zero-Day Protection: Integrates 7 new FortiGuard IPS signatures targeting IoT botnet command-and-control activities.
- Management Interface Hardening: Implements enhanced access controls to prevent unauthorized CLI access via web console (jsconsole).
Performance Optimization
- NP6 ASIC Utilization: Boosts SSL inspection throughput by 22% through hardware-accelerated session resumption techniques.
- Memory Allocation: Reduces latency spikes in environments with >100 concurrent VLAN interfaces.
- SD-WAN Health Monitoring: Adds BGP route stability checks for hybrid cloud deployments.
Protocol Enhancements
- QUIC Protocol Support: Enables granular traffic shaping for Google Workspace and Microsoft 365 applications.
- IPv6 Fragmentation Handling: Implements RFC 8200 compliance for 5G CPE device compatibility.
