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 VxRail versions before 7.0.200 contain a Plain-text Password Storage Vulnerability in VxRail Manager. A sys-admin user may exploit this vulnerability, leading to the disclosure of certain user credentials. The attacker may be able to use the exposed credentials to access the vulnerable application with privileges of the compromised account.

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 VxRail Manager before version 7.0.200 stores certain user credentials in plain text. A user with sys-admin privileges can exploit this to retrieve these stored credentials, potentially gaining unauthorized access to the application with the compromised account's privileges.

MitigationUpgrade VxRail Manager to version 7.0.200 or later to resolve the plain-text password storage vulnerability. Additionally, review and rotate potentially exposed credentials and limit sys-admin access to reduce risk.

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 if Dell VxRail Manager is deployed
    Locate VxRail Manager components in your environment - typically this runs as a virtual appliance within the VxRail cluster infrastructure
    Affected if VxRail Manager is present in the environment
  2. Determine the installed VxRail Manager version
    Access the VxRail Manager administrative interface or use the VxRail API to query the current version number
    Affected if version cannot be determined or is earlier than 7.0.200
  3. Compare version against affected range
    Review the version number obtained and determine if it is below 7.0.200
    Affected if version is below 7.0.200

The environment is affected if VxRail Manager is installed and the running version is earlier than 7.0.200, as earlier versions store certain credentials in plaintext.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
