Introduction to cisco-asa-fp2k.9.20.2.10.SPA Software

The ​​cisco-asa-fp2k.9.20.2.10.SPA​​ package delivers Cisco Adaptive Security Appliance (ASA) software version 9.20.2.10 for Firepower 2100 series platforms, providing enterprise-grade firewall capabilities and VPN services. Released on March 14, 2024, this maintenance update addresses critical security vulnerabilities while enhancing platform stability for organizations requiring robust network threat prevention.

Designed specifically for Firepower 2100 series hardware (FPR-2110, FPR-2120, etc.), the software combines ASA’s proven stateful inspection with modern security integrations. It operates on Cisco’s Firepower 2100 chassis running FXOS 2.12.1.52 or later, enabling administrators to transition between ASA and Firepower Threat Defense (FTD) software stacks while maintaining hardware acceleration benefits.

Key Features and Improvements

1. ​​Enhanced Cryptographic Performance​​

The update introduces hardware-accelerated DTLS 1.3 decryption on Firepower 2100 series ASICs, achieving 35Gbps TLS throughput. This enables inspection of encrypted traffic without compromising network latency for high-density deployments.

2. ​​Security Vulnerability Mitigations​​

Cisco patched three critical CVEs in this release:

  • ​​CVE-2024-20351​​ (CVSS 8.6): Snort-based DoS vulnerability
  • ​​CVE-2024-20272​​ (CVSS 7.5): ASA VPN session hijacking flaw
  • ​​CVE-2024-20307​​ (CVSS 6.8): X.509 certificate validation bypass

3. ​​Management Optimizations​​

  • Simplified Smart Licensing migration from Call Home to Smart Transport protocols
  • Extended cluster node support for 16-node configurations in large-scale deployments
  • Improved API response times for XML-based management operations

4. ​​Platform Stability Upgrades​​

  • Reduced memory leaks in IPSec IKEv2 implementations
  • Fixed packet drops occurring during BGP route flapping events
  • Resolved TFTP service interruptions when handling files >2GB
