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 EMC VxRail versions 4.7.410 and 4.7.411 contain an improper authentication vulnerability. A remote unauthenticated attacker may exploit this vulnerability to obtain sensitive information in an encrypted form.

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 · moderate confidence

Dell EMC VxRail versions 4.7.410 and 4.7.411 contain an improper authentication vulnerability that allows remote unauthenticated attackers to bypass authentication mechanisms and obtain sensitive information stored in encrypted form.

MitigationApply the vendor-supplied patch or upgrade to a fixed version beyond 4.7.411 when released by Dell EMC. As a Hyper-Converged Infrastructure appliance, patching should follow Dell's documented update procedures.

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 VxRail firmware version
    Access the VxRail Manager UI or use the command 'vxrail-cli -t get-version' to retrieve the installed firmware version. Alternatively, check via the vCenter plugin or REST API endpoint /v1/cluster/version.
    Affected if Version is 4.7.410, 4.7.411, or 4.7.510 on a D560 or D560f model.
  2. Confirm VxRail model type
    From the VxRail Manager UI under Settings > System > Hardware, or via the REST API /v1/nodes, verify the model is either D560 or D560f.
    Affected if Model is D560 or D560f AND firmware version is in the affected list.
  3. Verify management network exposure
    Check if the VxRail Manager management interface (typically ports 443, 22) is accessible from untrusted networks. Review firewall rules and network segments. Use 'show network' from VxRail CLI or check vCenter networking configuration.
    Affected if Management interface is exposed to networks outside the trusted administrative zone.
  4. Check authentication configuration status
    Review authentication settings in VxRail Manager under Security > Authentication Services. Confirm whether local accounts, LDAP, or other auth mechanisms are enabled and properly configured.
    Affected if Authentication is configured and the vulnerable firmware versions (4.7.410, 4.7.411, 4.7.510) are running.

A user is affected if they are running VxRail D560 or D560f firmware versions 4.7.410, 4.7.411, or 4.7.510 with management interfaces network-accessible to untrusted actors.
