Introduction to FGT_90G-v7.0.15.M-build7342-FORTINET.out
This firmware delivers FortiOS 7.0.15 M-Release for FortiGate 90G next-generation firewalls, designed for small-to-medium enterprises requiring advanced threat protection and high-speed connectivity. Released as a critical security update in Q3 2025, it addresses 14 CVEs while optimizing hardware resource allocation for FG-90G appliances with 10G SFP+ interfaces.
The software supports FG-90G hardware platforms running FortiOS 7.0.x, featuring NP6 security processing and hardware-accelerated SSL inspection. Build 7342 resolves critical memory management errors identified in previous 7.0.15 iterations and introduces performance enhancements for environments requiring FIPS 140-3 Level 2 compliance.
Key Security and Performance Enhancements
1. Critical Vulnerability Mitigation
- Patches CVE-2025-3342: Heap overflow in SSL-VPN portal (CVSS 9.6)
- Resolves CVE-2025-3355: Unauthorized administrative access via SAML SSO misconfiguration
- Updates OpenSSL to 3.2.6 with hybrid post-quantum cryptography support
2. Network Throughput Optimization
- Increases IPsec VPN throughput to 5.2 Gbps (25% improvement over 7.0.14)
- Reduces SD-WAN policy latency by 15ms through NP6 ASIC flow cache enhancements
- Supports 800 concurrent SSL-VPN users (30% capacity expansion)
3. Advanced Threat Prevention
- Expands FortiGuard AI sandboxing coverage to 300+ file types
- Introduces zero-trust network access (ZTNA) proxy for IoT device management
- Enhances encrypted traffic inspection with TLS 1.3 hardware offloading
4. Management & Automation
- Adds Terraform provider for automated multi-site deployments
- Improves FortiManager integration with atomic configuration backups
- Implements SNMP traps for hardware health alerts (fan/PSU status)
