Introduction to cisco-mso-3.0.3i.aci Software
This critical security update resolves CVE-2021-1388 authentication bypass vulnerability in Cisco ACI Multi-Site Orchestrator (MSO) 3.0 deployments. Designed for Cisco Application Services Engine platforms, the 3.0(3i) release strengthens API endpoint security while maintaining multi-cloud policy synchronization across ACI fabrics. Cisco officially released this patch on February 24, 2021 to address the CVSS 10.0-rated vulnerability affecting MSO’s token validation mechanism.
Key Features and Improvements
- Security Reinforcement
- Implements strict JWT token validation for Northbound REST APIs
- Adds role-based access control (RBAC) for Kubernetes namespace mapping
- Multi-Site Enhancements
- 40% faster policy synchronization across 32-site fabrics
- Improved fault tolerance for cross-domain endpoint groups
- Compliance Updates
- FIPS 140-3 compliant TLS 1.3 implementation
- Audit trail logging for all infrastructure changes
Compatibility and Requirements
| Supported Platforms | Minimum ASE Version | Restricted Configurations |
|---|---|---|
| Cisco Application Services Engine | 1.1.3a | VMware ESXi < 6.7U3 |
| Nexus 9300-EX/FX Series | NX-OS 14.0(3h) | Non-ACI managed switches |
| Cisco UCS C220 M5 | 64GB RAM | Third-party SDN controllers |
This update requires simultaneous installation of Cisco APIC 5.2(3n) or later for full functionality. Incompatible with previous MSO 3.0(x) versions due to modified authentication protocols.
