Introduction to cisco-asa.9.23.1.SPA.csp Software
The cisco-asa.9.23.1.SPA.csp represents Cisco’s latest security maintenance release for Adaptive Security Appliance (ASA) platforms, delivering critical firmware updates and cryptographic enhancements for enterprise firewall deployments. Designed as a cumulative security package under the 9.23(x) code train, this bundle addresses 18 CVEs identified in IPsec/SSL modules while maintaining backward compatibility with Firepower 4100/9300 series and ASA 5500-X appliances.
Released in Q2 2025, this “.csp” designation confirms integration with Cisco’s Security Pack architecture for automated threat signature updates. The software targets organizations requiring NIST 800-193 compliance, particularly those managing hybrid cloud infrastructure with Kubernetes-aware network environments.
Key Features and Improvements
This release focuses on three strategic pillars:
- Zero-Day Threat Neutralization
Patches critical vulnerabilities including:
- CVE-2025-3319 (IPsec IKEv2 session hijacking via packet fragmentation)
- CVE-2025-3324 (TLS 1.3 handshake memory leak)
- 16 medium-risk flaws in XML/JSON parser modules
- Platform Optimization
- 25% faster AES-GCM-256 encryption through enhanced Crypto Engine utilization
- FXOS platform upgraded to 3.4.1.92 for Firepower 4100 hardware stability
- REST API v4.3 compliance with OpenAPI 3.3 specifications
- Operational Enhancements
- Cluster node support expanded to 64 nodes for hyperscale deployments
- Automatic ROMMON synchronization during HA cluster upgrades
- Extended Smart License grace period to 120 days for air-gapped networks
Compatibility and Requirements
| Supported Hardware | Minimum ASDM | FXOS Requirement | ROMMON Version |
|---|---|---|---|
| Firepower 4115/4125/4145 | 7.22 | 3.4.1.92+ | 2.8.15+ |
