All VPN anonymity destroyed in 3 min with Javascript exploit

We have always recommended that you run Noscript (or similar) with our VPN service. Javascript is a security risk, and is the #1 method of compromising privacy and security. (especially if js is being used in conjunction with Java) This type of exploit has been around for a long time. It is how the FBI attacked Tor through Freedomhosting, and it was around for years prior to that. Disabling Javascript is not the "temporary solution". It should ALWAYS be disabled unless you trust the site, and it is https, and you've verified the cert. Edit: Grammar More on reddit.com

Here is a simple solution that will allow you to fetch value from opened window. All you need is to inject JavaScript code into opened window that will interact with the parent window using window.opener:

HTML

<input id="value" />
<button onclick="openWindow();">Open</button>

JavaScript

function openWindow() {
    var i, l, options = [{
       value: 'first',
       text: 'First'
    }, {
       value: 'second',
       text: 'Second'
    }],
    newWindow = window.open("", null, "height=200,width=400,status=yes,toolbar=no,menubar=no,location=no");  

    newWindow.document.write("<select onchange='window.opener.setValue(this.value);'>");
    for(i=0,l=options.length; i<l; i++) {
        newWindow.document.write("<option value='"+options[i].value+"'>");  
        newWindow.document.write(options[i].text);  
        newWindow.document.write("</option>");
    }
    newWindow.document.write("</select>");
}

function setValue(value) {
    document.getElementById('value').value = value;
}

filter: alpha(opacity=75);
-ms-filter: "alpha(opacity=75)";
-khtml-opacity: .75;
-moz-opacity: .75;
background: #B8B8B8;
position: absolute;
left: 0px;
top: 0px;
height: 100%;
width: 100%;
z-index:990
}

#msgbx {
position: absolute;
left: 50%;
top: 50%;
height: 150px;
width: 350px;
margin-top: -75px;
margin-left: -175px;
background: #fff;
border: 1px solid #ccc;
box-shadow: 3px 3px 7px #777;
-webkit-box-shadow: 3px 3px 7px #777;
-moz-border-radius: 22px;
-webkit-border-radius: 22px;
z-index:999
}
