Introduction to FGT_92D-v5-build0736-FORTINET-5.2.9.out Software
This firmware release (build0736) delivers essential security patches and system optimizations for FortiGate 92D appliances running FortiOS 5.2.9, specifically addressing vulnerabilities in SSL inspection modules and VPN implementations. Released under Fortinet’s Legacy Support Program in Q3 2023, this build enhances the platform’s 1.2 Gbps threat protection throughput while maintaining backward compatibility with legacy network configurations.
Designed for the FortiGate 92D hardware – a desktop-form firewall supporting 30 IPSec VPN tunnels and 200,000 concurrent sessions – this update resolves 6 CVEs documented in Fortinet’s August 2023 security advisories. The build0736 revision provides extended lifecycle support for organizations maintaining 5.2.x series deployments.
