​​Introduction to FGT_60D-v5-build0754-FORTINET-5.2.11.out Software​​

This firmware package (build 0754) delivers FortiOS 5.2.11 for FortiGate 60D next-generation firewalls, originally released in Q2 2017 to address critical security vulnerabilities and enhance network stability. Designed specifically for the 60D hardware platform, it supports legacy enterprise networks requiring long-term firmware maintenance without upgrading to newer FortiOS versions.

The release focuses on maintaining compatibility with older infrastructure while addressing 12 CVEs identified in 2016-2017, including fixes for SSL-VPN session hijacking risks and IPv4 policy bypass vulnerabilities. Compatible only with the 60D model, it does not support newer devices like 60E or 60F series.
