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
Authorization bypass through User-Controlled key vulnerability in MeWare Software Development Inc. PDKS allows Privilege Abuse. This issue affects PDKS: from V16.20200313 before VMYR_3.5.2025117.

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 is an authorization bypass vulnerability where user-controlled input is used to determine access permissions in the PDKS system, allowing an authenticated user to abuse privileges and access resources or functions they should not have access to.

MitigationUpgrade PDKS to version VMYR_3.5.2025117 or later. If upgrading is not immediately possible, review access control implementations and ensure authorization decisions are not based on user-controllable parameters.

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 PDKS installation
    Locate PDKS system files, services, or applications in your environment. Check common installation directories or use system inventory tools to confirm PDKS presence.
    Affected if PDKS is installed and running in the environment
  2. Determine installed PDKS version
    Use the system's built-in version command, check configuration files, or query the PDKS service for its version number. Common methods include: pdks --version, checking version files in the installation directory, or querying the service API.
    Affected if Version is lower than VMYR_3.5.2025117 or version cannot be determined
  3. Inspect authorization implementation
    Review the source code, configuration files, or access control settings where authorization decisions are made. Look for instances where user-supplied parameters (such as user IDs, roles, or permissions passed in requests) are used directly to determine access rights without validation.
    Affected if Authorization logic accepts and uses user-controllable input to grant or deny access to resources or functions
  4. Verify access control for sensitive functions
    Test or inspect whether authenticated users can access resources or administrative functions beyond their assigned permissions by manipulating input parameters in API calls, web requests, or configuration settings.
    Affected if Users can access resources or functions outside their authorized scope by modifying input parameters

You are affected if PDKS is installed and the version is lower than VMYR_3.5.2025117, or if authorization decisions rely on user-controllable parameters regardless of version.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade PDKS to version VMYR_3.5.2025117 or later. If upgrading is not immediately possible, review access control implementations and ensure authorization decisions are not based on user-controllable parameters.

Recommended fix Moderate confidence

VMYR_3.5.2025117

  1. 1. Identify current installed version of MeWare PDKS software
  2. 2. If version is between V16.20200313 and VMYR_3.5.2025117 (exclusive), the system is vulnerable
  3. 3. Obtain the fixed release VMYR_3.5.2025117 from MeWare Software Development Inc.
  4. 4. Review release notes and any migration documentation provided by vendor
  5. 5. Perform a full backup of the PDKS database and configuration files
  6. 6. Test the upgrade in a non-production environment if possible
  7. 7. Apply the upgrade VMYR_3.5.2025117 following vendor installation instructions
  8. 8. Verify the IDOR vulnerability is remediated by testing authorization controls
Caveat Unknown; review vendor release notes for any configuration or functional changes in VMYR_3.5.2025117
