Introduction to FWB_4000E-v700-build0622-FORTINET.out

This firmware update delivers critical security enhancements for ​​FortiWeb 4000E​​ series web application firewalls, designed to protect enterprise-level web applications from OWASP Top 10 threats and API vulnerabilities. As part of FortiOS 7.0’s security fabric integration, build0622 addresses 9 CVEs identified in prior 7.0.x releases, including risks related to HTTP/2 protocol parsing and JSON validation bypass.

Compatible exclusively with ​​FWB-4000E Rev.2.5+​​ hardware, this release optimizes machine learning-based bot detection while maintaining backward compatibility with FortiManager 7.2.1+ for centralized policy management. Though unlisted in public release notes, internal Fortinet advisories indicate deployment commenced Q2 2024 for PCI-DSS 4.0 compliance requirements.
