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
An insecure direct object reference in MK-Auth 23.01K4.9 allows attackers to access and send support calls for other users via manipulation of the chamado parameter through a crafted GET request.

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

MK-Auth 23.01K4.9 contains an Insecure Direct Object Reference (IDOR) vulnerability in the support call functionality. Attackers can manipulate the 'chamado' parameter in GET requests to access and send support tickets belonging to other users, bypassing proper authorization controls.

MitigationImplement proper authorization checks to verify the authenticated user owns or has permission to access the specific support call before returning or modifying any data. Use session-based validation rather than relying on user-controllable object references.

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 MK-Auth installation
    Locate the MK-Auth web application directory or check running services on the host. Common locations may include /var/www/, /opt/, or the web server document root. Look for files or directories named 'mk-auth' or similar.
    Affected if MK-Auth software is present on the system
  2. Determine installed MK-Auth version
    Check version information in the application - typically found in an about page, config file, or the main index file. Compare the installed version against 23.01K4.9.
    Affected if The installed version matches or falls within the range of 23.01K4.9 (if version ranges beyond this single version are known to be affected)
  3. Verify support call module is enabled
    Access the MK-Auth administrative interface and check if the support ticket or 'chamado' functionality is present and enabled. This may appear as a support, tickets, or chamado menu item.
    Affected if The support call (chamado) module is accessible and enabled in the application
  4. Inspect support call request parameters
    If you have access to the application, navigate to the support call feature and examine GET requests. Look for a 'chamado' parameter in the URL used to access or view specific tickets.
    Affected if The application uses a 'chamado' parameter to reference support tickets in GET requests
  5. Test for IDOR vulnerability
    If you have multiple test accounts, access a support ticket with one account, then modify the 'chamado' parameter value in the GET request to reference a ticket ID belonging to a different user. Verify if unauthorized access is granted without proper authorization.
    Affected if Changing the 'chamado' parameter value allows access to support tickets belonging to other users

A defender is affected if MK-Auth version 23.01K4.9 is installed with the support call module enabled and the 'chamado' parameter in GET requests permits unauthorized access to other users' tickets.

Mitigation

Implement proper authorization checks to verify the authenticated user owns or has permission to access the specific support call before returning or modifying any data. Use session-based validation rather than relying on user-controllable object references.
