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 security flaw has been discovered in code-projects Online Product Reservation System 1.0. This affects an unknown function of the file /handgunner-administrator/register_code.php of the component User Registration Handler. Performing a manipulation of the argument fname/lname/address/city/province/country/zip/tel_no/email/username results in sql injection. The attack can be initiated remotely. The exploit has been released to the public and may be used for attacks.

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 the User Registration Handler of code-projects Online Product Reservation System 1.0 allows remote attackers to inject malicious SQL queries through multiple user input fields (fname, lname, address, city, province, country, zip, tel_no, email, username) in the file /handgunner-administrator/register_code.php.

MitigationImplement parameterized queries (prepared statements) for all user inputs in the registration handler, apply strict input validation, and ensure the database user follows least privilege principles.

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. Confirm application installation
    Locate the Online Product Reservation System installation by searching for register_code.php or the application's web root directory. Common paths may include /handgunner-administrator/ or similar admin directories.
    Affected if The application Fabian Online Product Reservation System version 1.0 is installed on the server.
  2. Verify vulnerable file presence
    Check for the existence of the file /handgunner-administrator/register_code.php in the web root. If this file exists, the SQL injection vulnerability may be present.
    Affected if The file register_code.php exists in the /handgunner-administrator/ directory.
  3. Confirm version is 1.0
    Identify the installed version of the Fabian Online Product Reservation System. Check any version files, about pages, or metadata within the application for the exact version number.
    Affected if The installed version is exactly 1.0.
  4. Verify registration endpoint is accessible
    Test if the registration handler is reachable by attempting to access the registration page or submitting a request to /handgunner-administrator/register_code.php.
    Affected if The registration endpoint is exposed and accessible over the network.
  5. Inspect registration code for SQL injection vulnerability
    Review the source code of register_code.php to confirm that user input fields (fname, lname, address, city, province, country, zip, tel_no, email, username) are used directly in SQL queries without parameterized queries or prepared statements.
    Affected if The code uses direct string concatenation for SQL queries with user inputs without proper sanitization or prepared statements.

A server is affected if it runs Fabian Online Product Reservation System version 1.0 with the accessible file /handgunner-administrator/register_code.php that contains unsanitized SQL queries using user input fields.
