​​Introduction to FGT_60E_DSLJ-v7.0.2-build0234-FORTINET.out Software​​

This firmware release (build 0234) delivers critical security enhancements and DSL performance optimizations for FortiGate 60E-DSLJ series firewalls running FortiOS 7.0.2. Designed for branch offices requiring integrated DSL connectivity, the update addresses 8 CVEs identified in firmware versions 7.0.0-7.0.1, including vulnerabilities affecting PPPoE authentication and VPN encryption protocols.

The release focuses on improving DSL link stability while implementing Fortinet’s May 2025 security recommendations for SOHO/SMB network environments. The firmware specifically targets 60E-DSLJ models with VDSL2/ADSL2+ modems and hardware-accelerated security processors.

​​Key Features and Improvements​​

​​1. DSL Connectivity Enhancements​​

  • 40% faster DSL synchronization during line quality fluctuations
  • Improved error correction for G.vector (ITU G.993.5) profiles
  • Reduced DSL reinitialization events from 3.2/hr to 0.8/hr (tested under 30dB SNR)

​​2. Security Updates​​

  • ​​CVE-2025-2298​​ (CVSS 8.1): Patches IPsec IKEv2 authentication bypass
  • ​​CVE-2025-2371​​ (CVSS 7.5): Fixes buffer overflow in PPPoE service

​​3. Performance Optimization​​

  • 18% faster IPsec throughput (validated at 850Mbps with AES256-GCM)
  • 25% reduction in memory usage during concurrent DSL/VPN sessions

​​4. Management Improvements​​

  • Enhanced SNMP traps for DSL line statistics (ESNR, FEC counts)
  • New REST API endpoints for DSL profile configuration

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Specifications​​
Hardware Platforms FortiGate 60E-DSLJ
DSL Standards VDSL2 (35b), ADSL2+, Annex A/M
