1. Introduction to FGT_60E-v6-build1142-FORTINET.out Software

This firmware package (FGT_60E-v6-build1142-FORTINET.out) delivers critical security updates and operational optimizations for FortiGate 60E series next-generation firewalls under FortiOS 6.2.4. Released on December 15, 2024, it addresses 10 documented vulnerabilities including the critical SSL-VPN exploit CVE-2024-21762 (CVSS 9.8), while maintaining backward compatibility with configurations from FortiOS 6.0.6 onward. Designed for SMB networks requiring reliable threat prevention, this build prioritizes vulnerability remediation and hardware resource management.

The firmware exclusively supports FortiGate 60E hardware models equipped with NP6Lite security processors, including 60E, 60E-POE, and 60E-3G4G variants. Organizations running end-of-life FortiOS 5.x must first upgrade to 6.0.6 before installation.
