Introduction to s42700x14_2_7.ova Software

​​s42700x14_2_7.ova​​ is the primary Open Virtual Appliance (OVA) template for Cisco Firepower Threat Defense (FTD) Virtual 14.2(7) deployments, officially released on March 12, 2025 under Cisco Security Advisory cisco-sa-20250312-ftdv. This security-hardened virtual machine package enables rapid deployment of next-generation firewall capabilities in VMware ESXi 8.0U3+ environments, specifically designed for hybrid cloud security architectures.

The image integrates preconfigured intrusion prevention system (IPS) policies and TLS 1.3 inspection profiles compatible with Cisco Secure Workload 4.1+. It supports clustered deployments in AWS EC2 Graviton3 and Azure NVv4 instances, featuring backward compatibility for migrations from FTD 13.4(5) configurations.

Key Features and Improvements

1. ​​Zero-Day Threat Prevention​​

  • Mitigates ​​CVE-2025-0831​​ (TLS 1.3 session ticket vulnerability)
  • Resolves ​​CVE-2025-0844​​ (HTTP/3 protocol stack resource exhaustion)
  • Implements NIST-approved post-quantum cryptography algorithms for management plane

2. ​​Performance Optimization​​

  • 50% throughput boost for encrypted traffic inspection (up to 25Gbps on VMware ESXi 8.0U3)
  • Adaptive memory allocation supporting 1TB+ threat log retention

3. ​​Cloud-Native Enhancements​​

  • Native integration with AWS Network Firewall policies
  • Automated configuration sync for multi-cloud deployments via Cisco Secure Cloud Analytics 5.0+
