​​Introduction to FGT_100E-v7.2.3.F-build1262-FORTINET.out​​

The ​​FGT_100E-v7.2.3.F-build1262-FORTINET.out​​ firmware delivers critical security updates and performance enhancements for Fortinet’s ​​FortiGate 100E​​ next-generation firewall, designed for branch offices and mid-sized enterprises requiring robust network protection. Released in Q4 2024, this update addresses 6 CVEs rated high-to-critical severity while optimizing resource allocation for environments with up to 1,500 concurrent VPN sessions.

Exclusively compatible with the ​​FortiGate 100E series​​, this build integrates FortiOS 7.2.3 architecture to combat advanced persistent threats (APTs) targeting SD-WAN deployments. It introduces enhanced SSL inspection capabilities through NP6 ASIC acceleration and supports hybrid mesh firewall configurations with FortiManager 7.4.5+.

​​Key Features and Improvements​​

1. ​​Critical Vulnerability Remediation​​

  • Patches ​​CVE-2024-23110​​ (CVSS 9.1), a buffer overflow vulnerability in IPv6 packet processing identified in FortiOS 7.2.0–7.2.2.
  • Resolves improper certificate validation in FGFM protocol implementations (​​CVE-2024-23592​​, CVSS 8.3).

2. ​​Performance Optimization​​

  • Increases IPsec VPN throughput by 15% (up to 4.8 Gbps) through enhanced NP6 ASIC resource allocation.
  • Reduces memory consumption during TLS 1.3 inspection by 20% through optimized session table management.

3. ​​Enhanced Protocol Support​​

  • Implements post-quantum TLS 1.3 with Kyber-768 algorithm for NIST SP 800-208 compliance.
  • Adds Modbus/TCP and DNP3 protocol deep inspection for industrial IoT device visibility.

4. ​​Management Upgrades​​

  • Introduces granular RBAC controls for Azure AD-integrated SSL-VPN access policies.
  • Supports FortiAnalyzer 7.4.3+ for centralized threat correlation across multi-site deployments.
