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
A vulnerability was detected in MuFen-mker PHP-Usermm up to 37f2d24e51b04346dfc565b93fc2fc6b37bdaea9. This affects an unknown part of the file /chkuser.php. Performing manipulation of the argument Username results in sql injection. The attack may be initiated remotely. The exploit is now public and may be used. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The vendor was contacted early about this disclosure but did not respond in any way.

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

SQL injection vulnerability in MuFen-mker PHP-Usermm's /chkuser.php file allows remote attackers to inject malicious SQL queries via the Username parameter. The lack of input sanitization or parameterized queries enables attackers to manipulate database queries, potentially leading to unauthorized data access or data manipulation.

MitigationImplement prepared statements/parameterized queries for all database operations involving user input. Alternatively, implement strict input validation and sanitization on the Username parameter before using it in SQL queries.

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 MuFen-mker PHP-Usermm installation
    Search your web root directories for the presence of the MuFen-mker PHP-Usermm application files, particularly looking for directories containing 'usermm' or 'mufen' in the name
    Affected if The application is present in your environment
  2. Locate the vulnerable chkuser.php file
    Check for the file chkuser.php within the usermm or application directory structure - typically found in the application's root or includes folder
    Affected if The file /chkuser.php exists in your installation
  3. Verify the Username parameter handling
    Examine the chkuser.php source code and search for SQL query construction involving the 'Username' parameter without prepared statements or parameterization
    Affected if The code uses the Username parameter directly in SQL queries without escaping or prepared statements (look for patterns like "SELECT...WHERE username='$Username'" or "...username=" . $_POST['Username'])
  4. Confirm external access to the vulnerable endpoint
    Determine if chkuser.php is accessible via HTTP/HTTPS without authentication - check if the file is reachable from the web and does not require login to access
    Affected if The chkuser.php endpoint is accessible externally without authentication

You are affected if MuFen-mker PHP-Usermm is installed, the chkuser.php file exists, and the Username parameter is used in SQL queries without prepared statements or input sanitization and is accessible to attackers
