This vulnerability has a CVSS 3.0 base score of 4.9, rated MEDIUM. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

In Cloudera Navigator Key Trustee KMS 5.12 and 5.13, incorrect default ACL values allow remote access to purge and undelete API calls on encryption zone keys. The Navigator Key Trustee KMS includes 2 API calls in addition to those in Apache Hadoop KMS: purge and undelete. The KMS ACL values for these commands are keytrustee.kms.acl.PURGE and keytrustee.kms.acl.UNDELETE respectively. The default value for the ACLs in Key Trustee KMS 5.12.0 and 5.13.0 is "*" which allows anyone with knowledge of the name of an encryption zone key and network access to the Key Trustee KMS to make those calls against known encryption zone keys. This can result in the recovery of a previously deleted, but not purged, key (undelete) or the deletion of a key in active use (purge) resulting in loss of access to encrypted HDFS data.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
