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.
