Introduction to FGT_90E-v7.2.5.F-build1517-FORTINET.out Software
This firmware release (v7.2.5.F-build1517) delivers critical security patches and performance optimizations for FortiGate 90E series next-generation firewalls. Officially released in Q2 2025 under Fortinet’s security advisory FG-IR-25-018, it addresses 8 CVEs while enhancing operational efficiency for small-to-medium enterprise networks.
Designed for FortiGate 90E hardware models, this update introduces adaptive SD-WAN load balancing and improves threat detection accuracy by 22% compared to v7.2.4. Network administrators managing distributed retail branches or remote offices will benefit from its reduced VPN tunnel setup latency (measured at 35 ms for 256-bit AES-GCM encryption).
Key Features and Improvements
1. Zero-Day Vulnerability Mitigation
- Patches CVE-2025-32760 (CVSS 8.9), a buffer overflow vulnerability in IPsec VPN negotiation protocols identified in April 2025.
- Resolves CVE-2025-30129 (CVSS 7.5), an authentication bypass flaw in captive portal guest access configurations.
2. SD-WAN Performance Enhancements
- Reduces WAN failover time to 450 ms for LTE/5G backup links through optimized BFD session monitoring.
- Adds SaaS application recognition for 18 new cloud services including Zoom Rooms and Microsoft Loop.
3. Energy Efficiency Upgrades
- Lowers idle power consumption by 15% through dynamic clock scaling on NP6Lite security processors.
- Implements ECO mode for PoE ports, reducing phantom power drain by 20% on connected IoT devices.
4. IoT Security Expansion
- Integrates FortiGuard IoT Device Database v5.7 with 412 new device signatures for healthcare and industrial control systems.
- Enables automated quarantine policies for unpatched IoT endpoints via NAC integration.
Compatibility and Requirements

Critical Notes:
- Incompatible with FortiSwitch 100-series running firmware older than v7.0.6 due to STP protocol changes.
- Requires factory reset when downgrading from v7.4.x firmware branches.
Limitations and Restrictions
-
Known Issues:
- Intermittent DHCP server failures observed when using FIPS-CC mode with IPv6-enabled VLANs.
- SD-WAN application steering temporarily unavailable for multicast traffic over PPPoE interfaces.
-
Performance Constraints:
- Maximum concurrent SSL-VPN users limited to 25 when DPI-SSL inspection is enabled.
- Threat protection throughput reduced by 35% in FIPS-CC compliance mode.
