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. The web login functionality allows an attacker to bypass authentication and gain client privileges via SQL injection in central/executar_login.php.

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

SQL injection vulnerability in MK-AUTH 19.01's login functionality (central/executar_login.php) allows attackers to bypass authentication and gain client-level access by injecting malicious SQL queries into the login parameters.

MitigationRemediate by replacing dynamic SQL queries with parameterized queries or prepared statements in the login functionality, and implement proper input validation to prevent SQL injection attacks.

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 if MK-AUTH is installed
    Search the system for MK-AUTH installation directories or check running web services for MK-AUTH application files
    Affected if MK-AUTH software is found on the system
  2. Determine the installed MK-AUTH version
    Locate the version file or check application metadata that displays the installed MK-AUTH version number
    Affected if The installed version is exactly 19.01
  3. Locate the vulnerable login script
    Search for the file central/executar_login.php within the MK-AUTH web application directory structure
    Affected if The file central/executar_login.php exists in the application
  4. Verify login functionality is accessible
    Check if the MK-AUTH web interface login page is exposed and reachable via network access (HTTP/HTTPS to the central endpoint)
    Affected if The login functionality is network-accessible without additional authentication

You are affected if MK-AUTH version 19.01 is installed and the central/executar_login.php file exists in an accessible login deployment.
