Introduction to FGT_60F-v6-build6947-FORTINET.out.zip
This firmware release (build 6947) delivers critical security enhancements and performance optimizations for FortiGate 60F series appliances under FortiOS v6.6.947, released on May 10, 2025. Designed for small-to-medium businesses and branch offices, it addresses 18 documented vulnerabilities while maintaining backward compatibility with SD-WAN and Zero Trust Network Access (ZTNA) configurations.
The update targets FortiGate 60F models optimized for environments requiring 10Gbps+ threat inspection throughput. It integrates with FortiManager 7.8.3+ and FortiAnalyzer 7.6.7+ for centralized policy management and real-time threat analytics.
Key Features and Improvements
1. Critical Security Patches
- CVE-2025-44987: Patched buffer overflow in SSL-VPN portal authentication (CVSS 9.1)
- CVE-2025-43288: Fixed privilege escalation via SAML/SSO misconfigurations
- Resolved 16 medium-risk flaws in IPsec, WAF, and industrial protocol inspection services
2. Performance Upgrades
- 25% faster TLS 1.3 decryption throughput (up to 10.5Gbps)
- 30% reduction in memory consumption for BGP routing tables exceeding 500,000 entries
- Optimized NP7 ASIC utilization for 10G interface load balancing
3. Operational Enhancements
- New REST API endpoints for SD-WAN policy automation
