I guess they would fail a question on the first quiz in the class I teach,


In javascript, "document.cookie" will return the cookie...  It has nothing
to do with whether it is written to disk.

<script>alert(document.cookie)</script> is the most common way that a XSS is
demonstrated.  See the XSS vulnerabilities in a website portal:


Their assertion doesn't reassure me as to their understanding of
vulnerabilities and secure programming.  But, they already demonstrated
their level of understanding by making javascript a requirement for the
operation of their product.
