Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Dell XtremIO X2 XMS versions prior to 6-4-1.11 contain an improper access control vulnerability. A remote read only user could potentially exploit this vulnerability to perform add/delete QoS policies which are disabled by default.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Dell XtremIO X2 XMS versions prior to 6-4-1.11 contain an improper access control vulnerability where a remote read-only user can bypass authorization checks to add or delete QoS policies, which should be privileged operations disabled by default for read-only accounts.

MitigationUpgrade Dell XtremIO XMS to version 6-4-1.11 or later to remediate the improper access control vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify XMS firmware version
    Access the Dell XtremIO X2 management interface or use the XMS CLI command to retrieve the current firmware version (typically via 'show system-info' or similar command in the XMS interface)
    Affected if The installed version is below 6.4.1-11 (e.g., 6.4.0-x, 6.3.x, or earlier)
  2. Verify read-only user accounts exist
    Check the user management section of the XMS interface or use the user list command to confirm that read-only role accounts are configured on the system
    Affected if One or more read-only user accounts are present in the system configuration
  3. Confirm QoS policy management is available
    Access the QoS policy management feature within the XMS interface or API and attempt to enumerate existing QoS policies to verify the feature is enabled and accessible
    Affected if QoS policy management functionality is present and accessible to authenticated users
  4. Test read-only user authorization for QoS operations
    Using a read-only user account credentials, attempt to perform a QoS policy add or delete operation through the XMS API or web interface to verify if authorization bypass exists
    Affected if A read-only user can successfully add or delete QoS policies without receiving an authorization error

The environment is affected if the XMS firmware version is below 6.4.1-11 AND read-only users can successfully modify QoS policies when they should only have view access.

Upgrade available Upgrade to 6.4.1-11 or later
Fixed in 6.4.1-11
Interim mitigation

Upgrade Dell XtremIO XMS to version 6-4-1.11 or later to remediate the improper access control vulnerability.

Recommended fix Moderate confidence

XMS version 6.4.1-11 or later

  1. Ensure you have a valid backup of XtremIO X2 configuration before starting the upgrade
  2. Schedule a maintenance window as firmware upgrades may cause brief service interruptions
  3. Download the XMS firmware version 6.4.1-11 or later from Dell support portal (support.dell.com)
  4. Log into XtremIO XMS admin interface using administrative credentials
  5. Navigate to the firmware update or system maintenance section
  6. Upload and apply the 6.4.1-11 firmware package
  7. Monitor the upgrade progress and verify all cluster nodes are running the new version
  8. After upgrade, verify that read-only users can no longer add/delete QoS policies
Caveat Firmware upgrades on storage arrays may cause brief I/O interruptions; ensure proper backup and test in non-production environment first
