Version Details:
- Build Number: 0632 (7.0.15.M)
- Release Type: Maintenance Release (MR)
- Release Date: May 2025 (aligned with Fortinet’s quarterly security update cycle)
Key Features and Improvements
1. Critical Security Patches
This firmware resolves CVE-2025-53103, a high-risk heap overflow vulnerability in SSL-VPN implementations (CVSS 9.0), preventing unauthenticated remote code execution through malformed authentication requests. Additional security enhancements include:
- Mitigation of CVE-2025-49925 in FortiGuard web filtering certificate validation
- Quantum-resistant encryption upgrades for FGFM protocol communications
2. Operational Optimization
- Throughput Improvement: 18% faster IPSec VPN performance for 2,500+ concurrent tunnels
- HA Cluster Stability: Reduced failover latency to <0.4 seconds in active-active configurations
- Memory Management: Solved resource leaks during sustained 18 Gbps DDoS attacks
3. Protocol & Feature Updates
- Full support for TLS 1.3 with Encrypted Client Hello (ECH)
- Expanded Zero Trust Network Access (ZTNA) metadata logging for Microsoft Entra ID integrations
- Updated FortiGuard threat intelligence to v25.478+ (2,200+ new malware signatures)
