Detection Guidance

This vulnerability is a Cross Site Scripting (XSS) issue in the WordPress Automotive Car Dealership Business Theme versions 13.3.3 and below. Detection typically involves testing for reflected XSS by sending crafted requests to the web application and observing if injected scripts are executed.

Common detection methods include using web vulnerability scanners or manual testing with payloads in URL parameters, form inputs, or other user-controllable fields.

Example commands using curl to test for reflected XSS might include sending a request with a script payload in a parameter and checking the response for the injected script:

• curl -i "http://targetsite.com/page?param=<script>alert(1)</script>"
• Observe the response body for the presence of the injected script tag.

Additionally, using tools like OWASP ZAP or Burp Suite can automate detection of reflected XSS vulnerabilities by scanning the site and injecting test payloads.

Since no official patch is available yet, applying the mitigation rule from Patchstack or updating the theme when possible is advised.
