Introduction to FGT_100D-v6-build1378-FORTINET-6.2.15.out Software
The FGT_100D-v6-build1378-FORTINET-6.2.15.out firmware package is a critical security update for Fortinet’s FortiGate 100D firewall series, specifically addressing CVE-2024-21762 – a 9.8 CVSS-rated remote code execution vulnerability in SSL-VPN services. Released in Q4 2024 under Fortinet’s Extended Security Maintenance program, this build (6.2.15) provides essential protections for organizations maintaining legacy network infrastructure requiring PCI DSS 3.2.1 or HIPAA compliance.
Designed exclusively for FG-100D hardware platforms, this update balances vulnerability remediation with backward compatibility for industrial control systems using deprecated protocols like TLS 1.0/1.1. The firmware maintains support for FortiManager 6.2.x centralized management while implementing mandatory security hardening for federal networks.
Key Features and Improvements
1. Critical Vulnerability Resolution
- CVE-2024-21762 Patch: Eliminates unauthenticated RCE risk in SSL-VPN through memory boundary validation for chunked HTTP/1.1 requests
- TLS 1.3 Optimization: Reduces 18% CPU overhead during bulk encrypted session establishment
2. Performance Enhancements
- Resolves memory fragmentation issues affecting IPS engine stability in 10,000+ concurrent session environments
- Improves SD-WAN application steering logic for legacy MPLS/VoIP deployments by 22%
3. Compliance Features
- Pre-configured NIST 800-53 audit templates for SC-7 (boundary protection) controls
- PCI DSS 3.2.1 report automation for Requirement 11.3 (penetration testing validation)
4. Protocol Support
- Maintains compatibility with Cisco ASA 5500-series IPsec VPN configurations
- Extends RADIUS accounting support for legacy NAC solutions using PAP authentication
