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
Incorrect Privilege Assignment vulnerability in Mesalvo Meona Client Launcher Component, Mesalvo Meona Server Component enables the export  of user data, including cleartext passwords, via the SQL editor. This issue affects Meona Client Launcher Component: through 19.06.2020 15:11:49; Meona Server Component: through 2025.04 5+323020.

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

This vulnerability in Mesalvo Meona Client Launcher and Server Components allows privileged users to export user data, including cleartext passwords, through the SQL editor due to incorrect privilege assignment. The issue grants excessive permissions that bypass proper access controls, enabling unauthorized data exfiltration.

MitigationImplement proper role-based access control (RBAC) to restrict SQL editor functionality, remove or encrypt cleartext password storage, and audit all privilege assignments to ensure least-privilege原则 is enforced.

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. Confirm Mesalvo Meona installation
    Locate the Meona application installation directory or check system inventory/software list for 'Meona' or 'Mesalvo Meona'
    Affected if Meona clinical software is present in the environment
  2. Identify SQL editor feature availability
    Log into the Meona application with a standard authenticated user account and navigate to the SQL editor module or data export functionality
    Affected if The SQL editor is accessible to non-administrative user accounts
  3. Verify user role assignments for SQL access
    Access the user role management or permission configuration within Meona and examine which roles are assigned access to the SQL editor or data export features
    Affected if Standard or non-admin roles have permissions to use the SQL editor or export user data
  4. Check database for cleartext passwords
    Execute a query via the SQL editor (if accessible) or directly on the database to examine the user password storage format: SELECT password FROM users or similar table containing credentials
    Affected if User passwords are stored in cleartext rather than hashed format
  5. Validate data export capability for user records
    Use the SQL editor to craft and execute a query that exports user records or sensitive data fields
    Affected if Authenticated users can export data containing passwords or other sensitive user information without elevated privileges

A user is affected if they have Mesalvo Meona installed and the SQL editor is accessible to non-administrative user accounts, allowing them to retrieve user data including cleartext passwords.
