Introduction to FGT_92D-v6-build0443-FORTINET-6.0.13.out Software
This firmware release (FGT_92D-v6-build0443-FORTINET-6.0.13.out) addresses critical security vulnerabilities and enhances operational stability for FortiGate 90D Series next-generation firewalls. As part of FortiOS 6.0.13, it specifically targets legacy hardware models requiring extended security maintenance, including the FortiGate 90D, 80D, and 60D appliances.
The build was released on December 28, 2024, aligning with Fortinet’s Security Fabric updates to mitigate high-risk exploits like CVE-2024-21762, a critical SSL-VPN remote code execution (RCE) vulnerability. This firmware ensures compliance with global cybersecurity regulations while maintaining compatibility with older network infrastructures.
Key Features and Improvements
Critical Security Patches
- CVE-2024-21762 Mitigation: Resolves a CVSS 9.8-rated vulnerability affecting SSL-VPN services, where improper memory handling allowed unauthenticated attackers to execute arbitrary code through crafted HTTP chunk trailers.
- Enhanced Memory Protections: Implements boundary checks for SSL-VPN packet processing to prevent buffer overflow attacks.
Performance Optimizations
- Reduced latency in IPsec VPN tunnel establishment by 15% through optimized cryptographic handshakes.
- Improved stability for low-memory devices during sustained DDoS attacks.
Legacy Hardware Support
- Extended firmware lifecycle management for End-of-Support (EoS) devices, ensuring continued threat protection without hardware upgrades.
