Defect Information


Defect IDHeadline
CSCwi43360Cert expiry on Sept 2024 for DNS Security registration to Umbrella cloud

Problem Description


The SSL digital certificate that is used by Cisco Catalyst SD-WAN Routers to register with the Cisco Secure Access service expires on September 30, 2024. Cisco SD-WAN Routers with the expired certificate will fail to register with the Cisco Secure Access service. The result of this failure is that any attempts to set up new Secure Service Edge (SSE) tunnels using Cisco SD-WAN policy groups will fail.


Background


The Cisco Secure Access solution (formerly Cisco Umbrella) uses digital certificates during the SSL handshake process to establish secure HTTPS connections. For SSE, this connection is with the Cisco Secure Access endpoint, which allows for the identification of the public IP address of the device. The current SSL certificate on affected Cisco SD-WAN Routers expires on September 30, 2024.

This problem affects the following Cisco products if they are running an affected Cisco IOS XE Software release and if they are in SD-WAN Controller mode:

  • Aggregation Services Routers (ASRs)
  • Catalyst 8000 Routers
  • Catalyst 8000v Edge
  • Catalyst IR Rugged Series Routers
  • Integrated Services Routers (ISRs)

Note: Devices that are running Cisco IOS XE Software Release 17.14.1 or later are not affected. These newer software releases already contain the updated digital certificate.


Problem Symptom


Affected devices will fail to establish secure connections with the Cisco Secure Access service and any attempts to set up new SSE tunnels using Cisco SD-WAN policy groups will fail.

Note: Devices that are configured for SSE tunnels that are already in operation will not be impacted until reboot. The expired certificate is used only during device registration with the Cisco Secure Access service. Device registration occurs when the Cisco Secure Access service is initially configured or when the configured device is rebooted.

 

 

 


Workaround/Solution


Solution

Affected devices must have the affected certificate replaced with a new, unexpired certificate. The new certificate is valid until the year 2035. Customers who do not currently use SSE tunnels as part of Cisco Secure Access integration, but who expect to deploy it in the future, can replace the affected certificate by upgrading the Cisco SD-WAN Router software to a release that contains the new certificate. The new certificate is installed automatically during the upgrade. Devices that are running Cisco IOS XE Software Release 17.14.1 or later already contain the updated digital certificate.

For affected devices, the following X1 certificate must be downloaded and installed:
