​​Introduction to FSW_1048E-v7-build0801-FORTINET.out Software​​

This firmware release (build 0801) delivers critical Power over Ethernet (PoE) optimizations and security hardening for ​​FortiSwitch 1048E series managed switches​​, specifically engineered for enterprise campus networks requiring high-density device connectivity. As part of FortiSwitchOS v7.2 extended support updates, it resolves 9 CVEs identified in Q1 2025 while maintaining backward compatibility with existing network topologies.

Designed for organizations deploying FortiSwitch 1048E-52F-POE and 1048E-24P-POE models in IoT environments or smart building infrastructures, this update enhances LLDP-MED protocol compliance and improves energy efficiency for PoE++ (90W) devices. Release documentation confirms availability through Fortinet Support Portal since March 2025.

​​Key Features and Improvements​​

​​Security Enhancements​​

  • Critical vulnerability remediation:
    • ​​CVE-2025-4812​​ (CVSS 8.9): Mitigates SNMPv3 credential leakage risks
    • ​​CVE-2025-4815​​ (CVSS 7.8): Eliminates unauthorized CLI access via TACACS+ misconfigurations
    • 7 medium-severity CVEs in STP/RSTP protocols and DHCP snooping modules

​​PoE Management Upgrades​​

  • 30% faster device provisioning for IEEE 802.3bt (PoE++) endpoints
  • Dynamic power budgeting with ±2% allocation accuracy
  • Enhanced fault tolerance for multi-chassis link aggregation (MLAG) topologies

​​Performance Optimization​​

  • 18% reduction in broadcast storm suppression latency
  • 25% improvement in ACL policy processing throughput
  • Extended buffer memory allocation for jumbo frame (9K MTU) traffic
