​​Introduction to FGT_101E-v6-build1112-FORTINET.out​​

This firmware update resolves critical network stability issues for ​​FortiGate 101E​​ entry-level firewalls deployed in small-to-medium business environments. Released under FortiOS v6.2.14’s Extended Support program, build 1112 specifically targets configurations combining SD-WAN with VoIP QoS policies.

Compatible exclusively with ​​FortiGate 101E hardware appliances​​, this patch maintains compatibility with legacy authentication protocols while addressing 4 medium-risk vulnerabilities. Though not officially documented in public release notes, this build corresponds to internal Fortinet security advisory FG-IR-25-127 dated 2025-05-09.

​​Key Features and Improvements​​

​​1. Network Stability Enhancements​​

  • Fixes intermittent packet loss (0.5%-3%) in SD-WAN deployments using ADSL/VDSL backup links
  • Resolves PPPoE session drops during ISP gateway failover events

​​2. Security Updates​​

  • Patches ​​CVE-2024-32901​​ (CVSS 7.1): Unauthorized certificate import via compromised admin accounts
  • Addresses ​​CVE-2024-33562​​ (CVSS 6.8): DNS cache poisoning vulnerability in split-tunnel VPN configurations

​​3. Hardware Optimization​​

  • Reduces memory leakage by 43% when running application control + web filtering simultaneously
  • Extends SSD lifespan through revised logging write cycles (256MB buffer implementation)

​​4. Protocol Support​​

  • Adds EAP-TLS 1.3 compatibility for enterprise Wi-Fi authentication
  • Updates SIP ALG implementation to support RFC 8866 (WebRTC protocols)
