Product & Service Introduction:
===============================
Magento is an open source e-commerce web application that was launched on March 31, 2008 under the name Bento. It was developed 
by Varien (now Magento, a division of eBay) with help from the programmers within the open source community but is now owned 
solely by eBay Inc. Magento was built using parts of the Zend Framework. It uses the entity-attribute-value (EAV) database model 
to store data. In November 2013, W3Techs estimated that Magento was used by 0.9% of all websites.

Our team of security professionals works hard to keep Magento customer information secure. What`s equally important to protecting 
this data? Our security researchers and user community. If you find a site that isn`t following our policies, or a vulnerability 
inside our system, please tell us right away.

Technical Details & Description:
================================
An application-side cross site scripting web vulnerability has been discovered in the official Magento Connect web-application.
The vulnerability allows remote attackers to inject own script code on the application-side of the affected application module.

The vulnerability is located in the `claim%5Bclaimed_extension_url` value of the `magento-connect/claim/claim/new/` module.
Remote attackers are able to inject own script code on the application-side of the service to compromise user/moderator/admin 
session data. The request method to inject is POST and the attack vector is located on the application-side of the affected module.

Exploitation of the persistent input validation web vulnerability requires a low privileged web-application user account and low or medium user interaction. 
Successful exploitation of the vulnerability results in session hijacking, persistent phishing attacks, persistent external redirects to malicious source 
and persistent manipulation of affected or connected application modules (api).

Request Method(s):
						[+] POST

Vulnerable Service(s):
						[+] Magento Connect
						
Vulnerable Module(s):
						[+] magento-connect/claim/claim/new/
						
Vulnerable Parameter(s):
						[+] claim%5Bclaimed_extension_url


Proof of Concept (PoC):
=======================
The persistent vulnerability in the exception handling can be exploited by remote attackers without privileged application user account and low user interaction.
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.


Manual steps to reproduce the vulnerability ...
1. Surf to http://www.magentocommerce.com/magento-connect/claim/claim/new/  
2. In the Enter a link to the extension on Connect you believe violates our terms. write ...
Note: Payload "&gt;&lt;iframe src="javascript:alert(document.cookie)"&gt;&lt;/iframe&gt;
3. Successful reproduce of the security vulnerability!

POC: Exception Handling
&lt;div class="m_input_box w85p error"&gt;&lt;!-- add class 'error' to show error message--&gt;
                &lt;label for="link" class="required"&gt;Enter a link to the extension on Connect you believe violates our terms. &lt;/label&gt;
                &lt;input id="link" name="claim[claimed_extension_url]" value="" type="text"&gt;&lt;iframe src="javascript:alert(document.cookie)"&gt;&lt;/iframe&gt;"&gt;
                &lt;span class="error_txt"&gt;Required field. Example: http://www.magentocommerce.com/magento-connect/extension-name&lt;/span&gt;
