        <title>xss and zero byte chars</title>
        <description>Hi,

I'd like to prepare a proof-of-concept for an xss vulnerability that is based on sending a zero-byte character before the actual malicious code. Without that \0, the applications IPS will refuse the request.

I can't manage to place a zero-byte inside an auto-submitting HTML form. How can I do this?

Thanks!</description>

            <description><![CDATA[multipart/form-data would work unencoded, but if it rejects it it's not very useful.<br />
<br />
There are a bunch of other mimes supported by Mozilla: http://mxr.mozilla.org/mozilla2.0/source/netwerk/mime/nsMimeTypes.h#129<br />
<br />
But they probably default to application/x-www-form-urlencoded when you try to post text fields.]]></description>

            <description><![CDATA[I should mention that the forms enctype must be application/x-www-form-urlencoded, otherwise I can't circumvent the IPS that's running. I just can't get my browser to send out an unencoded zero byte.]]></description>
