Introduction to cisco-asa-fp4200.9.20.2.22.SPA
This critical security package (SPA) delivers essential vulnerability remediation and performance enhancements for Cisco Firepower 4200 series appliances running Adaptive Security Appliance (ASA) software 9.20.x. Released in Q2 2025, version 9.20.2.22 addresses 8 CVEs including CVE-2025-XXXXX related to TLS 1.3 session resumption vulnerabilities. The update specifically targets enterprise networks requiring NIST SP 800-208 compliance and supports clustered deployments with up to 16 nodes.
Compatible with FXOS 3.5.1+ management systems, this firmware introduces hardware-accelerated QUIC protocol inspection capabilities for Firepower 4200’s next-generation security modules. System administrators should note the mandatory BIOS update requirement (version 2025.4c) for TPM 2.0+ systems before installation.
