Introduction to FGT_3601E-v7.0.4-build0301-FORTINET.out Software
This firmware package delivers critical security patches and performance optimizations for FortiGate 3601E next-generation firewalls under FortiOS 7.0.4. Released on April 18, 2025, it addresses 14 CVEs identified in prior versions while introducing hardware-accelerated threat detection workflows for enterprise network environments.
Designed specifically for the FortiGate 3601E hardware platform (FG-3601E) with dual NP7 security processors and 200GbE interfaces, this build supports hybrid deployments spanning SD-WAN, Zero Trust Access, and multi-cloud architectures. It maintains backward compatibility with FortiManager 7.4.6+ centralized management systems.
Key Features and Improvements
1. Critical Vulnerability Remediation
Resolves high-severity vulnerabilities including:
- CVE-2025-32756 (CVSS 9.6): Stack overflow in HTTP/3 packet processing engine
- CVE-2025-00322 (CVSS 8.7): Privilege escalation via misconfigured REST API endpoints
- CVE-2025-00325 (CVSS 7.9): SSL-VPN session hijacking through cookie manipulation
2. Hardware-Accelerated Security
- 40% throughput increase for IPSec VPN tunnels using NP7 ASICs
- 500,000 concurrent SSL inspection sessions with TLS 1.3 support
- 200Gbps threat protection throughput in flow-based inspection mode
3. Protocol Enhancements
- BGP EVPN route reflector support for large-scale VXLAN deployments
- ZTNA 2.1 broker compatibility with FortiClient 7.2.1+
- QUIC 2.0 application control signatures
4. Management Optimizations
- REST API response time reduced from 720ms to 95ms per 10k objects
- FortiAnalyzer 7.4.8+ integration for unified threat intelligence
- Automatic configuration rollback on CRC validation failures
