cyberstrikeus CIS Red Hat OpenShift Container Platform Benchmark v1.8.0 - Control 1.2.31
Profile Applicability
- Level: 1
Description
OpenShift supported an option called unsupportedConfigOverrides that allowed users to opt into unsupported behavior. This option is no longer supported by OpenShift and should not be used.
Rationale
Users should stop using deprecated and unmaintained features in favor of supported features.
Impact
None. The feature is set to null by default and isn't used by default.
Audit Procedure
Make sure the unsupportedConfigOverrides in your deployment returns null using the following command:
oc get kubeapiserver/cluster -o jsonpath='{.spec.unsupportedConfigOverrides}'
The output should return null. Any other return value is a finding and you should migrate away from that particular configuration.
Remediation
None.
Default Value
By default, OpenShift sets this value to null and doesn't support overriding configuration with unsupported features.
