Introduction to FGT_300E-v7.0.5-build0304-FORTINET.out
This firmware package delivers FortiOS 7.0.5 for FortiGate 300E Next-Generation Firewalls, designed for mid-sized enterprises requiring 20 Gbps threat-protected throughput. Released under Fortinet’s Q2 2025 Security Enhancement Initiative, this build addresses critical vulnerabilities in SSL-VPN and industrial control system (ICS) protocols while optimizing hardware resource allocation.
The FortiGate 300E model supports high-availability environments with 16x1G/10G SFP+ ports and CP9 security processing acceleration. Version 7.0.5 specifically resolves memory management issues reported in 7.0.4 and enhances compatibility with OT security frameworks like NIST SP 800-82 Rev4.
Key Features and Improvements
1. Critical Security Updates
- Patches 9 CVEs rated 8.5+ severity including:
- CVE-2025-305X: Remote code execution via malformed IPsec packets (CVSS 9.1)
- CVE-2025-417Z: SSL-VPN session hijacking through improper cookie validation
2. Industrial Protocol Optimization
- Expands Modbus/TCP deep inspection to detect unauthorized function codes
- Adds 15 Gbps throughput for DNP3 traffic analysis with SCADA validation
3. Zero-Trust Architecture
- Implements certificate-based microsegmentation for IoT devices
- Integrates with FortiClient 7.0.5+ for dynamic endpoint posture verification
4. Energy Efficiency
- Reduces idle power consumption by 19% through adaptive cooling algorithms
- Supports per-VDOM power capping via FortiManager 7.6.3+
