<p>
    It is recommended to specify the HttpOnly flag to new cookie.
</p>

<h3>Risk</h3>

<p>
    Cookies that doesn't have the flag set are available to JavaScript running on the same domain.
    When a user is the target of a "Cross-Site Scripting", the attacker would benefit greatly from getting the session id.
</p>

<h3>Vulnerable Code</h3>

<pre>
var cookie = new HttpCookie("test");
</pre>

<h3>Solution</h3>

<b>Web.Config</b>
<pre>
&lt;httpCookies httpOnlyCookies="true" [..] /&gt;
</pre>

<pre>
var cookie = new HttpCookie("test");
cookie.Secure = true;
cookie.HttpOnly = true; //Add this flag
</pre>
