Introduction to FGT_60E_DSLJ-v6-build5168-FORTINET.out Software
This firmware release (FGT_60E_DSLJ-v6-build5168-FORTINET.out) delivers critical security updates and DSL network optimizations for FortiGate 60E-DSLJ routers, specifically designed for branch offices requiring integrated xDSL connectivity. Targeting vulnerabilities disclosed in FortiOS 6.5.x series, it resolves 8 CVEs while improving PPPoE stability and threat detection accuracy. Compatible exclusively with FortiGate 60E-DSLJ hardware (FG-60E-DSLJ), this build aligns with FortiOS 6.5.16 architecture and includes enhancements for low-latency VoIP traffic prioritization.
Key Features and Improvements
-
Security Enhancements:
- Mitigates CVE-2025-32756, a critical stack overflow vulnerability affecting HTTP/HTTPS management interfaces, with CVSS 9.6 severity.
- Addresses DSL-specific risks including PPPoE session hijacking (CVE-2025-33201) through improved CHAP authentication protocols.
-
DSL Performance Optimization:
- Reduces VDSL2 handshake latency by 22% through enhanced line synchronization algorithms.
- Improves packet prioritization for SIP/RTP traffic with 15% lower jitter in congested networks.
-
Protocol Support:
- Adds TLS 1.3 compliance for HTTPS inspection on DSL WAN interfaces.
- Enables dynamic bandwidth allocation for bonded DSL lines (G.998.x standards).
-
Management Upgrades:
- Introduces REST API v2.3 for automated xDSL line quality monitoring.
- Fixes FortiAnalyzer log export failures caused by timestamp mismatches in multi-timezone deployments.
