Introduction to FGT_60E_DSL-v6-build0272-FORTINET.out

This firmware package delivers FortiOS 6.0.6 for FortiGate 60E DSL devices, specifically addressing vulnerabilities in broadband-enabled network environments. Released under Fortinet’s Extended Support Program in Q4 2024, it combines critical security patches with performance enhancements for SMB and branch office deployments. The build0272 revision focuses on DSL modem stability and hybrid WAN optimization for networks using multiple ISP connections.

Targeted at organizations requiring reliable threat prevention in bandwidth-constrained scenarios, this update supports:

  • ​​FortiGate 60E DSL​​ appliances (FG-60E-DSL)
  • Hardware with integrated VDSL2/ADSL2+ modems
  • Networks using PPPoE/PPPoA broadband authentication

Key Features and Improvements

​​1. Security Enhancements​​

  • Mitigated ​​CVE-2024-48887​​ (CVSS 9.3): Eliminated unauthenticated configuration alteration risks in DSL interface settings
  • Patched memory overflow vulnerabilities in PPPoE client implementation (FG-IR-24-215)
  • Enhanced firmware signature verification to prevent malicious code injection

​​2. Connectivity Optimizations​​

  • 25% faster DSL synchronization times through improved line training algorithms
  • Dual-WAN failover reduced to <2 seconds during ISP outages
  • Support for RFC 4638-compliant jumbo frames (up to 9,216 bytes)

​​3. Management Upgrades​​

  • Added real-time DSL line statistics monitoring in FortiManager 7.2+
  • Compatible with FortiDeceptor 4.2 for automated breach simulation
