Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-732: Incorrect Permission Assignment for Critical Resource, where the product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors. In Github.com/cubefs/cubefs, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

CubeFS through 3.2.1 allows Kubernetes cluster-level privilege escalation. This occurs because DaemonSet has cfs-csi-cluster-role and can thus list all secrets, including the admin secret.
