CVE-2025-2241

Summary

A flaw was found in Hive, a component of Multicluster Engine (MCE) and Advanced Cluster Management (ACM). This vulnerability causes VCenter credentials to be exposed in the ClusterProvision object after provisioning a VSphere cluster. Users with read access to ClusterProvision objects can extract sensitive credentials even if they do not have direct access to Kubernetes Secrets. This issue can lead to unauthorized VCenter access, cluster management, and privilege escalation.

Weaknesses

  • CWE-922: Insecure Storage of Sensitive Information

Workarounds

A few mechanisms are available to reduce the risks and mitigate this vulnerability:

  1. Restrict Access to ClusterProvision Objects

Ensure that only trusted users with valid VCenter credentials have read access to ClusterProvision objects. This can be verified using the following commands:

oc adm policy who-can get clusterprovision oc adm policy who-can read clusterprovision

  1. Rotate VCenter Credentials

Immediately rotate VCenter credentials to revoke access for any users who may have already accessed the exposed credentials.

  1. Audit VCenter Users and Roles

Conduct a security audit of VCenter accounts and roles to detect any unauthorized access or configuration changes.

If any suspicious activity is found, revoke access by rotating credentials again (step 2) and taking necessary remediation actions.
