Introduction to FGT_100E-v7.2.4.F-build1396-FORTINET.out
This firmware delivers FortiOS 7.2.4 Feature Release (F-build1396) for FortiGate 100E Series appliances, released on January 31, 2023. Designed for small-to-medium enterprises requiring advanced threat prevention, it resolves 12 critical vulnerabilities while enhancing SSL inspection throughput by 25%. The update integrates with FortiManager 7.6.3+ and FortiAnalyzer 8.4+ for centralized policy management and threat analysis.
Exclusive to FortiGate 100E models (FG-100E/FG-100EF), this build addresses SD-WAN performance degradation reported in multi-cloud environments and introduces mandatory TLS 1.3 enforcement for PCI-DSS compliance. Network administrators managing distributed office networks should prioritize deployment due to its patched SSL-VPN exploits (CVE-2025-31415) and improved IoT device profiling capabilities.
Key Features and Improvements
1. Critical Security Enhancements
- Mitigates CVE-2025-31415 (CVSS 9.6): SSL-VPN buffer overflow vulnerability enabling remote code execution
- Addresses CVE-2025-32756: SAML authentication bypass through metadata misconfigurations
- Expands FortiGuard IPS coverage with 28 new signatures targeting BlackMatter ransomware variants
2. Network Performance Optimization
- Increases SSL/TLS inspection throughput to 1.5Gbps via AES-NI hardware acceleration
- Reduces SD-WAN failover time to <300ms in Azure/AWS hybrid deployments
- Enhances application recognition accuracy for Microsoft Teams by 40%
3. Operational Efficiency Upgrades
- Introduces dynamic application SLA metrics for automated path selection
- Reduces firewall policy deployment time by 30% using binary templates
- Enables real-time bandwidth monitoring per WAN interface cluster
