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 issue was discovered in MK-AUTH 19.01. There is authentication bypass in the web login functionality because guessable credentials to admin/executar_login.php result in admin access.

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

Authentication bypass vulnerability in MK-AUTH 19.01 web login (admin/executar_login.php) due to guessable/default credentials, allowing unauthorized attackers to obtain admin access to the system.

MitigationImmediately change the default/weak credentials to strong, unique passwords following best practices, and review the authentication mechanism for additional hardening such as account lockout policies and MFA.

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 version
    Locate the MK-AUTH installation and check the version information, typically found in system info pages, About section, or the main admin dashboard
    Affected if The installed version is exactly 19.01 (Mk Auth Mk Auth: = 19.01)
  2. Verify admin login page accessibility
    Access the admin/executar_login.php endpoint in a web browser or via curl to confirm the login page is reachable
    Affected if The admin login page is publicly or internally accessible without authentication restrictions
  3. Confirm default credentials are in use
    Attempt to log in using common default credentials (such as admin/admin, admin/password, or other vendor defaults documented for MK-AUTH)
    Affected if Login succeeds with default, factory-set, or easily guessable credentials
  4. Check for password change history
    Review user account settings or audit logs in the MK-AUTH admin panel to determine if default credentials have ever been changed
    Affected if No evidence exists of password modification since installation, or default credentials remain active

A system is affected if it runs MK-AUTH version 19.01 and has the default credentials still configured on the admin account, allowing unauthorized administrative access.

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.
