Introduction to cisco-asa.9.14.4.17.SPA.csp Software

The ​​cisco-asa.9.14.4.17.SPA.csp​​ is a critical security maintenance release for Cisco Adaptive Security Appliance (ASA) software, specifically designed for Firepower 2100/4100/9300 series appliances. This container service package (CSP) addresses multiple vulnerabilities while maintaining platform stability for enterprise firewall deployments.

Cisco ASA serves as the core security engine in these devices, providing stateful firewall capabilities, VPN concentrator functions, and intrusion prevention integration. Version 9.14.4.17 focuses on resolving specific memory management vulnerabilities identified in previous releases while maintaining backward compatibility with existing rule configurations.

This update maintains compatibility with:

  • Firepower 2100 series (up to ASA 9.20.x)
  • Firepower 4100 appliances
  • Firepower 9300 chassis
  • Virtual ASA instances on supported hypervisors
