1. Introduction to FWB_XENOPEN-v700-build0603-FORTINET.out Software

This firmware package delivers critical security updates for FortiWeb-VM Xen virtual appliances under FortiOS 7.0.3 branch. Released in Q2 2025, the build0603 revision specifically addresses memory management vulnerabilities in multi-tenant web application firewall deployments while maintaining compatibility with Citrix Hypervisor 8.2 environments.

Optimized for environments requiring 10Gbps+ SSL/TLS inspection throughput, the update supports FortiWeb-VM Xen instances (FWB_VM64_XEN) with virtual NP6 security processors. The maintenance release resolves 11 documented stability issues from previous 7.0.x versions, particularly those affecting XML external entity (XXE) processing during high-concurrency API traffic loads.
