​​Introduction to asr1000-universalk9_noli.16.03.02.SPA.bin​​

The ​​asr1000-universalk9_noli.16.03.02.SPA.bin​​ is a critical firmware package designed for Cisco ASR 1000 Series Aggregation Services Routers. This release focuses on resolving hardware tampering vulnerabilities, enhancing secure boot capabilities, and ensuring compatibility with modern network protocols. It supports Cisco ASR 1000 Series modular and consolidated chassis, including:

  • ​​Route Processors​​: ASR1000-RP1, ASR1000-RP2, ASR1000-RP3
  • ​​Embedded Services Processors (ESP)​​: ASR1000-ESP100, ASR1000-ESP200, ASR1000-ESP200-X
  • ​​Chassis​​: ASR1009-X, ASR1006, ASR1002-HX (from IOS XE 16.2.1r onward).

The firmware version ​​16.03.02​​ addresses critical security flaws identified in Cisco’s 2024–2025 PSIRT advisories, making it mandatory for enterprises prioritizing hardware integrity and compliance.

​​Key Features and Improvements​​

  1. ​​Hardware Tampering Mitigation​​

    • Resolves vulnerabilities in Field Programmable Gate Arrays (FPGA) and Complex Programmable Logic Devices (CPLD) by updating firmware signatures and secure boot validation processes.
    • Prevents unauthorized code execution during system reboots.

  2. ​​Secure Boot Enhancements​​

    • Implements FIPS 140-3 compliant ROMMON images to ensure cryptographic integrity during bootup.
    • Validates firmware hashes against Cisco’s Trust Anchor Module (TAM).

  3. ​​Hardware Compatibility Updates​​

    • Adds support for secondary IPv4/IPv6 subnets in BFD configurations to improve routing redundancy.
    • Optimizes VXLAN EVPN scalability for multi-tenant data center deployments.

  4. ​​Critical Bug Fixes​​

    • Addresses a memory leak in SIP40 modules when handling high-throughput traffic.
    • Fixes false-positive “SPA_POWERED_OFF” alerts caused by outdated SPA FPD firmware.

​​Compatibility and Requirements​​

​​Component​​ ​​Supported Models​​ ​​Minimum IOS XE Version​​
Route Processors ASR1000-RP1, ASR1000-RP2, ASR1000-RP3 2.4.0
ESP Modules ASR1000-ESP100, ASR1000-ESP200-X 15.2(4r)S
Chassis ASR1009-X, ASR1006, ASR1002-HX 16.2(1r)
Interface Cards ASR1000-2T+20X1GE, ASR1000-6TGE 16.3(2r)

​​Key Notes​​:

  • Do not downgrade to IOS XE releases earlier than ​​2.4.0​​ after applying this firmware.
  • ASR1001, ASR1002, and ASR1002-X routers are ​​not affected​​ by the patched vulnerabilities.
