Introduction to FGT_1101E-v7.0.15.M-build0632-FORTINET.out

This firmware release (FGT_1101E-v7.0.15.M-build0632-FORTINET.out) targets FortiGate 1101E next-generation firewalls, delivering critical security patches and operational optimizations under FortiOS 7.0.15.M. Designed for enterprise branch offices requiring PoE+ connectivity, it addresses 9 CVEs while enhancing SD-WAN traffic prioritization algorithms.

As part of Fortinet’s Extended Security Maintenance (ESM) program for 7.0.x branch, this build0632 revision specifically resolves memory leak issues in SSL-VPN services reported in CVE-2025-32756. Compatible only with 1101E hardware (SKU FG-1101E-POE), it requires minimum 8GB RAM and FortiManager 7.6.1+ for centralized management.

Key Features and Improvements

1. ​​Zero-Day Vulnerability Mitigation​​
