​​Introduction to FGT_300E-v6-build1723-FORTINET.out.zip Software​​

The ​​FGT_300E-v6-build1723-FORTINET.out.zip​​ file contains a critical firmware update for Fortinet’s FortiGate 300E series next-generation firewalls. Released in Q1 2025, this build (1723) addresses 7 high-severity vulnerabilities while optimizing threat detection capabilities under FortiOS 6. Designed for enterprise network security, it aligns with NIST SP 800-193 standards for firmware integrity verification and complies with FIPS 140-3 Level 2 requirements for government-grade deployments.

Specifically targeting ​​FortiGate 300E hardware models​​, this update resolves remote code execution (RCE) risks documented in Fortinet’s Q4 2024 PSIRT Advisory. Network administrators must prioritize deployment within 45 days to mitigate unauthenticated attack vectors.
