dbcve checksWork through these to decide whether this CVE applies to you.
-
Verify Cloudera Manager versionAccess the Cloudera Manager admin UI, go to Support > About, or run command: cm --version or check /etc/cloudera-scm/cmversion.propertiesAffected if The installed version is exactly 7.2.4
-
Confirm Cloudera Manager is runningCheck if the Cloudera Manager service is active: systemctl status cloudera-scm-server or ps aux | grep cloudera-scmAffected if Cloudera Manager service is running on version 7.2.4

Review all user accounts and their assigned roles for any unexpected administrative privilegesAffected if Any user account has privileges beyond what was originally assigned, or unauthorized admin roles exist
-
Check for unauthorized cluster accessReview the audit logs at Administration > Audit to look for actions performed by non-admin users that modify cluster configuration, user roles, or security settingsAffected if Audit logs show actions performed by users with limited roles that should not have been permitted
The environment is affected if Cloudera Manager version 7.2.4 is running and any user has gained privileges beyond their assigned role or unauthorized admin access exists
