​​Introduction to FGT_60D-v6-build0231-FORTINET-6.0.4.out Software​​

This firmware package (build 0231) delivers FortiOS 6.0.4 for FortiGate 60D next-generation firewalls, released in Q3 2022 to address critical security vulnerabilities and optimize network operations. Designed exclusively for the 60D hardware platform, it supports organizations requiring extended firmware support for legacy security infrastructure while maintaining compliance with modern cybersecurity standards.

The release resolves 9 CVEs identified between 2021-2022, including fixes for SSL-VPN session vulnerabilities and IPv6 policy bypass risks. Compatible only with the 60D model (FGT-60D), it does not support newer devices like 60E or 60F series.
