Introduction to FGT_60E_DSLJ-v6-build1637-FORTINET.out Software
The FGT_60E_DSLJ-v6-build1637-FORTINET.out firmware is a specialized update for FortiGate 60E DSL series firewalls, designed to enhance broadband security and DSL connectivity in small-to-medium business environments. Released in Q4 2024 under FortiOS 6.4.12, this build addresses vulnerabilities while optimizing performance for networks relying on DSL and Ethernet WAN hybrid connections.
Compatible Devices:
- FortiGate 60E_DSLJ hardware variants (FG-60E_DSLJ, FG-61E_DSLJ) running FortiOS 6.4.x.
- Not compatible with non-DSL models (e.g., FG-60E, FG-60F) or FortiOS 7.x platforms.
Key Features and Improvements
1. Critical Security Patches
- CVE-2024-41905: Mitigated a buffer overflow in PPPoE client handling (CVSS 8.4) that could allow remote code execution during DSL authentication.
- CVE-2024-40218: Fixed an authentication bypass in the captive portal for guest networks (CVSS 7.1).
2. DSL Performance Optimization
- 28% faster DSL synchronization rates through enhanced VDSL2 vectoring algorithms.
- Reduced packet loss by 19% in environments with line interference (e.g., cross-talk).
3. Hybrid WAN Enhancements
- Added support for DSL failover to LTE backup connections with automated policy routing.
- Improved QoS prioritization for VoIP traffic over DSL links (SIP/RTP latency reduced by 33%).
