widget failed security test (4 posts)

    I have a WP site that uses Security Metrics to run vulnerability tests periodically to be PCI compliant.

    When they ran that last test, they found that the MailChimp widget was vulnerable to xss javascript attacks. They also made me aware of where the code needed sanitization:

    <div id="mailchimp-widget" class="widget mailchimpSF_display_widget">	<a name="mc_signup_form"></a>
    	<h3>Sign up for Astro News</h3>    <div id="mc_signup_container">
    	<form method="post" action="/?\"><script>alert(123)</script>#mc_signup_form" id="mc_signup_form">

    Can I get some help on this? Thank you.

    You check with the MailChimp people?

    I haven't tracked down a way to do that. Do you happen to be on a Windows host? If so this may be the actual problem:

    If not, did they happen to give any details on how they injected that?

    @Brian Yes, they told me to post here.

    @mc_jesse I am on Linux. Yes, by typing js code with special characters into the form after what appears to be an appropriate email.

    In the meantime, I am going to use Gravity Forms MailChimp add-on.
