Critical Security Considerations
This firmware resolves vulnerabilities affecting 18% of deployed 100D series devices, including:
- CVE-2024-48922: Buffer overflow in IPsec IKEv1 implementation (CVSS 9.3)
- FG-IR-24-133: Unauthorized administrative session hijacking via crafted HTTP headers
Network administrators in financial and government sectors should prioritize deployment before December 2024 due to enhanced FIPS 140-2 Level 2 compliance.
Upgrade Recommendations
- Review complete release notes at Fortinet Document Library
- Perform configuration backup using “execute backup full-config” CLI command
- Allow 25-minute maintenance window per device for seamless upgrade
Note: Downgrading to versions below v6.0.0 after installation will disable SD-WAN features.
