Introduction to FGT_60E_DSL-v6.M-build2000-FORTINET.out Software

This firmware package (build 2000) delivers critical security updates and DSL performance optimizations for Fortinet’s FortiGate 60E-DSL appliance running FortiOS 6.4.15. Released under Fortinet’s Q2 2025 security advisory cycle, it addresses 7 CVEs rated “critical” or “high” severity while enhancing xDSL stability for remote branch deployments.

Specifically designed for the 60E-DSL hardware variant, this update introduces 25% faster threat inspection throughput and extends support for modern VDSL2 35b profiles. Network administrators managing distributed retail chains or telecom edge nodes will benefit from its improved PPPoE session handling and reduced bufferbloat latency.

Key Features and Technical Improvements

​​1. Security Infrastructure Upgrades​​

  • Patches CVE-2025-03215: Mitigates unauthorized configuration changes via management interfaces
  • Resolves DSL modem firmware vulnerability (FG-IR-25-254): Prevents remote code execution via crafted PPPoE packets
  • Updates FortiGuard IPS signatures with 34 new IoT exploit patterns

​​2. DSL Performance Enhancements​​

  • Implements ITU-T G.993.2 (VDSL2) Profile 35b support (300Mbps downstream)
  • Reduces DSL synchronization time by 40% through enhanced line diagnostics
  • Adds dynamic spectrum management for interference mitigation

​​3. Protocol & Management Updates​​

  • Implements TR-069 ACS compatibility for carrier-grade device management
  • Enhances PPPoE server capacity to 512 concurrent sessions
  • Supports BGP route dampening for stable ISP peering
