Introduction to FWB_4000F-v700-build0330-FORTINET.out Software
The FWB_4000F-v700-build0330-FORTINET.out firmware package represents Fortinet’s latest security enhancement for its FortiWeb 4000F series web application firewalls. Released in Q1 2025 as part of FortiOS 7.0’s extended support cycle, this build addresses critical vulnerabilities identified in enterprise web application environments while introducing performance optimizations for high-traffic networks.
Designed specifically for the FortiWeb 4000F appliance series, this firmware supports hardware models FWB-4000F and FWB-4000F-HA (High Availability configurations). It maintains backward compatibility with security policies created in FortiOS 6.4.15+ while implementing new encryption standards required for compliance with NIST SP 800-193 guidelines.
Key Features and Improvements
-
Zero-Day Attack Prevention
Implements real-time behavioral analysis with 43% faster pattern recognition compared to build 0311, reducing false positives in API traffic monitoring. Integrates updated FortiGuard Web Filtering signatures covering 12 new malware families. -
TLS 1.3 Full Support
Enables quantum-resistant cipher suites (CRYSTALS-Kyber/X25519) for SSL inspection, meeting FIPS 140-3 Level 2 certification requirements. Optimizes handshake latency by 31% through session resumption improvements. -
Vulnerability Remediation
Patches three critical CVEs:
- CVE-2024-32810: Remote code execution via malformed HTTP/2 headers
- CVE-2024-31492: Memory leak in XML parser
- CVE-2024-30155: Bypass of brute-force protection mechanisms
