Introduction to FGT_1100E-v7.2.1.F-build1254-FORTINET.out
FGT_1100E-v7.2.1.F-build1254-FORTINET.out is a critical firmware update for Fortinet’s FortiGate 1100E series appliances, designed to address high-risk vulnerabilities while enhancing enterprise network performance under FortiOS 7.2.1.F. Released on February 15, 2025, this build (1254) resolves 9 CVEs identified in Fortinet’s Q1 2025 security advisories, including a critical SSL-VPN authentication bypass vulnerability (CVE-2025-22891) scoring 9.6/10 CVSS v3.1.
Targeting mid-sized data centers, this firmware supports FortiGate 1100E hardware variants (1100E, 1100E-3G4G, and 1100E-HV Hypervisor Edition). It serves as the foundation for FortiOS 7.2’s Feature Release track, combining security hardening with SD-WAN performance optimizations for 40 Gbps throughput environments.
