Introduction to Cisco_Firepower_Threat_Defense_Virtual-6.7.0-65.tar.gz
This VMware ESXi deployment package provides the Firepower Threat Defense Virtual (FTDv) 6.7.0 software for securing virtualized environments. Released in October 2020 under Cisco Security Advisory cisco-sa-ftd-tls-dos-UNfP4kDZ, it addresses critical vulnerabilities while maintaining compatibility with legacy VMware infrastructure. The package contains:
- Cisco_Firepower_Threat_Defense_Virtual-ESXi-6.7.0-65.ovf: ESXi OVF template
- Cisco_Firepower_Threat_Defense_Virtual-6.7.0-65.vmdk: Virtual disk image
- SHA-256 verified manifest files
Primary supported platforms include:
- VMware ESXi 6.5 U3 / 6.7 U2 hosts
- Firepower 4100 Series hardware appliances
- AWS EC2 instances with nested virtualization
Key Features and Improvements
1. Critical Security Remediation
Resolves CVE-2020-3452 (CVSS 7.5) – a path traversal vulnerability in WebVPN services through enhanced URI validation logic. This update aligns with NSA’s Firepower Hardening Guide recommendations for virtualized deployments.
2. Performance Enhancements
- 25% faster TLS 1.3 handshake processing via optimized cryptographic libraries
- 18M concurrent connection capacity on 512GB RAM configurations
- Reduced HA failover time from 120s to 85s in cluster deployments
3. Management Upgrades
- Integrated Cisco Secure Workload API for dynamic policy adjustments
- FMC 6.7+ compatibility for centralized rule management
- vSphere 6.7 plugin support for VM resource monitoring
Compatibility and Requirements
| Component | Supported Versions | Notes |
|---|---|---|
| VMware ESXi | 6.5 U3 / 6.7 U2 | vCenter 6.7+ required |
| Firepower 4100 Series | Hardware Rev 2.1+ | 4120/4140/4150 models only |
| FXOS Platform | 2.8.1.105+ | For chassis management |
| RAM Allocation | 16GB (Min) / 512GB (Max) | 32GB recommended for IPSec |
Critical Limitations:
- Incompatible with ESXi 7.0+ or Hyper-V hypervisors
- Requires manual OVF template modifications for CloudForm deployments
- Cluster configurations demand identical NIC types across nodes
