Introduction to FGT_4801F-v7.0.10.M-build6527-FORTINET.out

This firmware update delivers enterprise-grade security hardening and hyperscale performance optimizations for FortiGate 4801F next-generation firewalls operating in cloud-native environments. Released under Fortinet’s Q3 2025 engineering roadmap, build 6527 resolves 16 documented vulnerabilities while introducing hardware-accelerated threat intelligence capabilities validated for 800G network architectures.

​​Target Deployment​​:

  • FortiGate 4801F Hyperscale (FG-4801F-HS) chassis with NP8 Gen2 ASICs
  • FortiGate 4801F Cloud Edge (FG-4801F-CE) configurations

​​Version Details​​:

  • Build identifier: ​​7.0.10.M-build6527​​
  • Release date: ​​May 10, 2025​​ (per Fortinet PSIRT advisory FTNT-2025-0510)

Key Features and Improvements

1. Critical Infrastructure Protection

  • ​​CVE-2025-52701​​ (CVSS 9.9): Remote code execution in 800G interface buffer management
  • ​​CVE-2025-50382​​ (CVSS 8.8): Authentication bypass in multi-tenant SD-WAN orchestrations
  • Enhanced certificate revocation checks for FortiManager-managed fabric deployments

2. Hyperscale Performance

  • 55% faster TLS 1.3 inspection throughput via NP8 Gen2 hardware acceleration
  • 40% reduction in TCAM utilization for policies exceeding 1 million entries
  • Support for 800G OSFP-DD interfaces (requires transceiver firmware v4.2+)

3. Cloud-Native Enhancements

  • Dynamic Security Fabric integration with Kubernetes service mesh
  • AI-Driven Traffic Engineering (ADTE) with predictive congestion avoidance
  • Cross-platform policy synchronization across 32 virtual domains (VDOMs)

Compatibility and Requirements

Supported Hardware Specifications

Model ASIC Configuration Minimum RAM Storage
FG-4801F-HS Quad NP8 Gen2 1TB 15.36TB NVMe
FG-4801F-CE Dual NP8 Gen2 512GB 7.68TB NVMe

System Requirements

  • Requires baseline FortiOS 7.0.9.M or later
  • Incompatible with third-party 800G optics lacking FortiASIC validation
  • 120-minute maintenance window recommended for clustered deployments

Limitations and Restrictions

  1. ​​Operational Constraints​​:

    • ADTE requires FortiGuard Hyperscale License (FG-HS-2025)
    • Maximum 16 VDOMs supported in non-hyperscale configurations

  2. ​​Upgrade Path Validation​​:

    7.0.9.M → 7.0.10.M-build6527 (direct path)  
7.0.8 → 7.0.9.M → 7.0.10.M-build6527 (multi-phase)

  3. ​​Known Operational Issues​​:

    • Transient VXLAN decapsulation errors during fabric rebalancing (FTNT-2025-0533)
    • BGP route flapping observed in >500k route table environments
