Detection Guidance

This vulnerability is a Reflected Cross-Site Scripting (XSS) issue in the Zingaya Click-to-Call WordPress plugin affecting the 'email', 'first_name', 'last_name', and 'phone' parameters on the plugin's sign-up admin page.

To detect this vulnerability on your system, you can attempt to send crafted HTTP requests to the sign-up admin page of the plugin with malicious script payloads in these parameters and observe if the scripts are reflected and executed.

• Use curl or similar tools to send requests with XSS payloads, for example:
• curl -G --data-urlencode "email=<script>alert(1)</script>" --data-urlencode "first_name=test" --data-urlencode "last_name=test" --data-urlencode "phone=123" "http://your-wordpress-site/wp-admin/admin.php?page=zingaya_signup"
• Observe the response in a browser or via tools that render HTML to check if the script is executed or reflected unescaped.

Note that the plugin was last updated 12 years ago and is currently closed pending review, so detection should focus on systems still running this plugin version.
