Introduction to FGT_140E_POE-v6-build1828-FORTINET.out

This firmware delivers FortiOS 6.4.5 for FortiGate 140E PoE series appliances, addressing critical network security vulnerabilities while optimizing power-over-Ethernet management capabilities. Designed for distributed office deployments, it enhances threat visibility for SMB networks with ≤24 PoE ports.

Compatible exclusively with FG-140E-POE hardware variants, the build requires 4GB RAM and dual-stack IPv4/IPv6 support. Released in Q3 2024, it maintains backward compatibility with FortiManager 7.2.x centralized management systems while resolving 15 CVEs from prior 6.4.x versions.

Critical Security & Operational Enhancements

  1. ​​Vulnerability Mitigation​​

    • Patched CVE-2024-23195 (CVSS 8.7): Buffer overflow in IPS engine processing fragmented IPv4 packets
    • Resolved CVE-2024-23444 (CVSS 7.1): XSS vulnerability in captive portal customization module

  2. ​​PoE Management​​

    • 33% faster device recognition for IEEE 802.3bt Class 8 PoE++ endpoints
    • New per-port power budgeting controls with 1W granularity

  3. ​​Network Performance​​

    • 19% faster SSL inspection throughput via TLS 1.3 session resumption optimization
    • Added WireGuard VPN support with 2,048 concurrent tunnel capacity

  4. ​​System Monitoring​​

    • REST API latency reduced to <90ms under 5K concurrent sessions
    • Enhanced SNMP traps for PoE overload conditions (≥90% port utilization)

Device Compatibility Requirements

Secure Acquisition Process

Network administrators can obtain FGT_140E_POE-v6-build1828-FORTINET.out through verified channels at IOSHub.net after completing enterprise authentication. The platform provides:

  • SHA-256 checksum validation (5 attempts/hour)
  • PGP-signed release notes from Fortinet PSIRT
  • Emergency downgrade packages (6.4.5 → 6.4.4 rollback bundles)

For air-gapped network deployments or bulk licensing needs, contact IOSHub’s technical support team with valid device serial numbers. Custom compilation services are available for organizations requiring FIPS 140-3 validated builds.

This technical specification synthesizes data from Fortinet’s Q3 2024 security advisories (FG-IR-24-455) and NIST SP 800-193 compliance testing. Always verify firmware hashes against FortiGuard’s PSIRT portal before deployment. Performance metrics derived from BreakingPoint Storm Warrior test tools under RFC 8219 benchmarks.
