  • FortiGate 60D hardware appliances (FG-60D)
  • Excludes PoE variants (FG-60D-POE) and virtual machine installations

​​Version Details​​:

  • Build identifier: ​​v6-build0457​​
  • Release cycle: Q4 2024 (aligned with extended security maintenance for legacy hardware)

Key Features and Improvements

1. ​​Critical Vulnerability Mitigations​​

  • Patched ​​CVE-2024-21762​​, a 9.8 CVSS-rated SSL VPN remote code execution vulnerability affecting FortiOS 6.x.
  • Updated IPS signatures (v22.45) to detect advanced cryptojacking and IoT botnet patterns.

2. ​​Hardware Performance Optimization​​

  • Reduced memory leaks by 32% during sustained SPI traffic inspection at 500Mbps throughput.
  • Improved NP4Lite ASIC utilization for concurrent IPS/IDS and web filtering operations.

3. ​​Legacy Protocol Support​​

  • Preserved compatibility with deprecated SSLv3/TLS 1.0 for legacy industrial control systems.
  • Fixed DHCP server crashes in VLAN-tagged multi-subnet configurations.
