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 classified as critical was found in SourceCodester Online Pizza Ordering System 1.0. This vulnerability affects unknown code of the file admin/ajax.php?action=login2 of the component Login Page. The manipulation of the argument email with the input abc%40qq.com' AND (SELECT 9110 FROM (SELECT(SLEEP(5)))XSlc) AND 'jFNl'='jFNl leads to sql injection. The attack can be initiated remotely. The complexity of an attack is rather high. The exploitation appears to be difficult. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-223300.

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 login functionality of SourceCodester Online Pizza Ordering System 1.0. The email parameter in admin/ajax.php?action=login2 is vulnerable to blind SQL injection, allowing remote attackers to inject arbitrary SQL commands using time-based techniques like SLEEP() to extract data from the database.

MitigationImplement parameterized queries (prepared statements) for all database queries involving user input, particularly in the login authentication flow. Apply input validation and escaping as an additional defense layer.

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 the application installation
    Locate the SourceCodester Online Pizza Ordering System installation directory on the web server. Check for files such as index.php or common entry points typical of this PHP application.
    Affected if The application is installed and accessible on the server.
  2. Verify the product version
    Inspect version files, readme files, or the database configuration for a version marker. Compare the installed version to the affected range (version 1.0).
    Affected if The installed version is exactly 1.0.
  3. Check for the vulnerable endpoint
    Locate the file admin/ajax.php in the installation directory. Verify that the file exists and is accessible via the web server.
    Affected if The file admin/ajax.php exists and is reachable.
  4. Examine the login2 action handler
    Open admin/ajax.php and locate the code handling the login2 action. Look for the code that processes the email parameter from the login form.
    Affected if The code handles a login2 action and processes an email parameter.
  5. Inspect SQL query implementation
    Review the SQL query code that uses the email parameter. Determine whether the query is constructed using direct string concatenation/concatenation of user input or uses parameterized queries (prepared statements).
    Affected if The email parameter is included in the SQL query through direct concatenation or string interpolation without using parameterized queries.

The environment is affected if the Online Pizza Ordering System version 1.0 is installed, the admin/ajax.php file exists, and the login2 action processes the email parameter using unsafe SQL query construction without prepared statements.
