Cross Site Scripting vulnerability in andrewtch88 mvc-ecommerce v.1.0 allows a remote attacker to execute arbitrary code and obtain sensitive information via the product_catalogue.php component

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

Cross-Site Scripting (XSS) vulnerability in the product_catalogue.php component of the andrewtch88 mvc-ecommerce v1.0 application allows remote attackers to inject malicious scripts through unsanitized user input, potentially leading to arbitrary code execution in users' browsers and sensitive information disclosure.

MitigationImplement input validation and output encoding/escaping on all user-supplied data rendered by product_catalogue.php, utilizing context-appropriate sanitization (e.g., htmlspecialchars for HTML body content) to prevent script injection.

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. Verify mvc-ecommerce installation exists
    Locate the application root directory and confirm the andrewtch88 mvc-ecommerce framework is present. Look for typical e-commerce directory structure (e.g., /var/www/html, /app, or similar web root paths).
    Affected if The application is not installed - if not found, this CVE does not apply.
  2. Confirm application version
    Check for a version file, composer.json, or README in the application root. Common locations: version.txt, README.md, or within package.json if using a JS framework. Compare the version to v1.0.
    Affected if Version is v1.0 - this specific version is listed as affected.
  3. Locate product_catalogue.php file
    Search the application source code for the file named product_catalogue.php. Common paths in MVC frameworks: /controllers/product_catalogue.php, /views/product_catalogue.php, or /app/Http/Controllers/product_catalogue.php.
    Affected if File does not exist - the vulnerability cannot be present.
  4. Identify user input handling in product_catalogue.php
    Open product_catalogue.php and examine the code for $_GET, $_POST, or $_REQUEST superglobals that receive user data. Look for parameters that are directly used in HTML output without sanitization functions such as htmlspecialchars, htmlentities, or similar escaping methods.
    Affected if User-supplied parameters are rendered in HTML output without encoding/escaping functions - the XSS vulnerability is present.
  5. Test for reflected input in browser
    If you have access to a test environment, navigate to the product_catalogue page and inject a benign test script tag in URL parameters (e.g., ?search=<script>alert(1)</script>). Observe whether the script executes or is reflected unescaped in the page source.
    Affected if The script tag executes or appears unescaped in page source - confirms active XSS vulnerability.

User is affected if they run andrewtch88 mvc-ecommerce v1.0 with the product_catalogue.php file present and user input reflected without sanitization.
