Affected Products and Versions

Remediation/Fixes

IBM strongly suggests the following:
App Connect Enterprise Certified Container 5.0 LTS (Long Term Support)

Only the DesignerAuthoring and IntegrationServer operands at version 12.0.8.0-r1-lts are affected.

To resolve this vulnerability, upgrade to App Connect Enterprise Certified Container Operator version 5.0.7 or higher, and ensure that all DesignerAuthoring and IntegrationServer components are at 12.0.8.0-r2-lts or higher. Documentation on the upgrade process is available at <https://www.ibm.com/docs/en/app-connect-contlts?topic=releases-upgrading-operator&gt;

Alternatively, if operands at 12.0.8.0-r1-lts must be used, the fix can be applied by updating the DesignerAuthoring and IntegrationServer operands to use a custom image

For a DesignerAuthoring instance, update the instance definition by setting the field “spec.integrationServer.containers.runtime.image” to the value “icr.io/cp/appc/ace-server-prod:12.0.8.0-r2-lts-20230421-155247@sha256:ea3a4c69678adad6acd3238ed94b690646dad1fb115a98d6398fdff2275ffa91”. See <https://www.ibm.com/docs/en/app-connect/container?topic=resources-designer-authoring-reference&gt; for more information

For an IntegrationServer instance, update the instance definition by setting the field “spec.pod.containers.runtime.image” to the value “icr.io/cp/appc/ace-server-prod:12.0.8.0-r2-lts-20230421-155247@sha256:ea3a4c69678adad6acd3238ed94b690646dad1fb115a98d6398fdff2275ffa91”.
