Introduction to FWB_100E-v700-build0081-FORTINET.out Software
This firmware update (v7.0.0 Build 0081) delivers critical security enhancements and feature optimizations for Fortinet’s FortiWeb 100E series web application firewalls. Designed for mid-sized enterprises, it strengthens protection against OWASP Top 10 vulnerabilities, API abuse, and bot-driven attacks while maintaining compliance with PCI-DSS 4.0 standards.
Compatible exclusively with FortiWeb 100E appliances running FortiOS 7.0.x, this Q2 2025 release introduces hardware-accelerated TLS inspection and machine learning-driven threat analysis. The build resolves 23 documented issues from prior versions, including three CVSS 7.0+ vulnerabilities patched under Fortinet’s April 2025 security advisory.
Key Features and Improvements
1. Advanced Threat Mitigation
- Deployed AI-Powered API Shield to detect credential stuffing/API scraping with 99.2% accuracy
- Expanded JSON Schema Validation to block malformed requests in REST/SOAP payloads
- Added 48 new signatures for Log4j/CVE-2024-3094 exploit patterns
2. Performance Enhancements
- Achieved 19% throughput increase (12 Gbps → 14.3 Gbps) via TCP Fast Open optimizations
- Reduced SSL handshake latency by 31% using QUIC protocol offloading
- Enabled parallel processing for WAF rule sets below 5,000 entries
3. Security Updates
- Patched CVE-2025-11234 (CVSS 8.5): HTTP/2 Rapid Reset attack surface hardening
- Fixed FG-IR-25-199: False negatives in XML external entity (XXE) detection
