​​Introduction to FGT_1500DT-v6-build1232-FORTINET.out Software​​

This firmware release (build 1232) delivers enterprise-grade security enhancements for FortiGate 1500DT series appliances, designed for hyperscale data centers requiring carrier-grade network protection. As part of FortiOS 6.4.12’s Long-Term Support (LTS) branch, it resolves 11 CVEs rated critical/high severity while optimizing threat inspection throughput up to 180Gbps through NP7 network processors.

Compatible with FortiGate-1500DT and 1500DT-F models, this Q4 2024 update introduces adaptive security protocols for software-defined perimeter architectures. It supports hyperscale VDOM configurations, making it ideal for telecom operators and managed security service providers (MSSPs) requiring multi-tenant firewall services.

​​Key Features and Improvements​​

​​1. Carrier-Grade Performance​​

  • ​​NP7 Acceleration​​: Achieves 120μs latency for IPS signature matching through hardware-optimized flow processing.
  • ​​Dynamic VDOM Scaling​​: Supports 1,000+ virtual domains with isolated security policies and resource allocation.

​​2. Critical Vulnerability Mitigation​​

  • Patches ​​CVE-2024-48850​​ (CVSS 9.6): Eliminates buffer overflow risk in SSL-VPN deep packet inspection module.
  • Fixes ​​CVE-2024-47591​​: Prevents configuration export via unauthorized XML API access.

​​3. Operational Enhancements​​

  • Adds REST API endpoints for FortiManager 7.4.9+ centralized orchestration.
  • Extends hardware lifecycle support to 10 years for critical infrastructure deployments.
