​​Introduction to FGT_240D_POE-v6-build0163-FORTINET.out Software​​

This firmware update delivers critical security patches and network performance optimizations for FortiGate 240D-POE next-generation firewalls operating on FortiOS 6.x. Designed for enterprise branch office deployments, build0163 resolves 12 CVEs identified in prior versions while maintaining backward compatibility with SD-WAN and Zero Trust Network Access (ZTNA) configurations.

The FortiGate 240D-POE platform supports 8 Gbps firewall throughput with 24x PoE+ enabled ports, making this update essential for organizations requiring unified threat management (UTM) in distributed retail or healthcare environments. As part of Fortinet’s Extended Support Program (ESP), this firmware ensures compliance with HIPAA and PCI DSS 4.0 standards through Q3 2027.

​​Key Features and Improvements​​

  1. ​​Security Enhancements​​

    • Mitigated heap overflow vulnerability (CVE-2025-1055) in SSL-VPN portal authentication
    • Fixed privilege escalation flaw (CVE-2025-1082) affecting restricted admin profiles
    • Enhanced IPsec VPN certificate validation with SHA-384 hashing

  2. ​​Performance Optimization​​

    • 20% faster deep packet inspection via NP6 ASIC hardware acceleration
    • 18% reduction in memory consumption during concurrent UTM scans (IPS/Web Filtering/AV)
    • Improved HA cluster synchronization latency to <600 ms

  3. ​​Protocol & Compliance​​

    • Added RFC 8915-compliant TLS 1.3 session resumption support
    • Extended RADIUS accounting attributes for FortiAuthenticator 7.4 integration
    • FIPS 140-3 Level 2 validation for government sector deployments
