Introduction to FGT_60D-v5-build1138-FORTINET.out
The FGT_60D-v5-build1138-FORTINET.out firmware package delivers critical security hardening for Fortinet’s FortiGate 60D unified threat management appliance, specifically addressing vulnerabilities identified in Q3 2017. Designed for small-to-medium business networks, this build (1138) represents the FortiOS 5.4.5 maintenance release that resolved 9 CVEs while maintaining backward compatibility with legacy configurations.
Compatible exclusively with the FortiGate 60D hardware platform, this firmware supports 10 network interfaces and 1Gbps firewall throughput. The “v5-build1138” designation confirms validation through Fortinet’s Quality Assurance process for devices running FortiOS 5.4 branch, originally released to address SSL-VPN vulnerabilities exploited in mid-2017 cyberattacks.
