CVE-2023-2878 (opens in a new tab)How to fix?
Upgrade github.com/kubernetes-sigs/secrets-store-csi-driver/pkg/secrets-store to version 1.3.3 or higher.
Overview
Affected versions of this package are vulnerable to Information Exposure in secrets-store-csi-driver where an actor with access to the driver logs can observe service account tokens. These tokens could then potentially be exchanged with external cloud providers to access secrets stored in cloud vault solutions.
Note: Tokens are only logged when the TokenRequests is configured in the CSIDriver object and the driver is set to run at log level 2 or greater via the -v flag.
To check if token requests are configured, run the following command:
kubectl get csidriver secrets-store.csi.k8s.io -o jsonpath="{.spec.tokenRequests}"
To check if tokens are being logged, examine the secrets-store container log:
kubectl logs -l app=secrets-store-csi-driver -c secrets-store -f | grep --line-buffered "csi.storage.k8s.io/serviceAccount.tokens"
