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
In CloudVision Portal all releases in the 2018.1 and 2018.2 Code train allows users with read-only permissions to bypass permissions for restricted functionality via CVP API calls through the Configlet Builder modules. This vulnerability can potentially enable authenticated users with read-only access to take actions that are otherwise restricted in the GUI.

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

CloudVision Portal 2018.1 and 2018.2 releases contain an authorization bypass where users with read-only permissions can bypass GUI-enforced role restrictions by making direct API calls through Configlet Builder modules, enabling unauthorized configuration changes.

MitigationUpgrade CloudVision Portal to version 2019.x or later where the permission bypass is patched, or implement API access controls to enforce role-based restrictions at the API layer.

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 installed CloudVision Portal version
    Access the CloudVision Portal About or System Information page, or use the CLI command 'show version' on the CVP cluster to retrieve the running version number
    Affected if The version falls within 2018.1.0-2018.1.4 or 2018.2.0-2018.2.3
  2. Confirm Configlet Builder module is in use
    Check if Configlet Builder functionality is accessible or enabled within the CloudVision Portal GUI under the Configlet or Builder sections
    Affected if Configlet Builder is accessible and active in the environment
  3. Verify read-only user permissions at API level
    Using a read-only user account, attempt a direct API call to Configlet Builder endpoints (such as /api/v1/configlets or /api/v2/configlets) and observe whether the request is rejected
    Affected if Read-only users can successfully execute API calls that modify configuration through Configlet Builder endpoints
  4. Review user role assignments
    Examine the role assignments for read-only users in CloudVision Portal under Users > Roles to confirm which roles are assigned
    Affected if Read-only roles are assigned and Configlet Builder API endpoints are not blocked for these roles

A user is affected if their CloudVision Portal version is within the 2018.1.0-2018.1.4 or 2018.2.0-2018.2.3 range AND read-only users can successfully make configuration changes via Configlet Builder API endpoints.
