Product & Service Introduction:
===============================
If you are a retailer and looking for a product to develop an on line store, then KonaKart could be a good match. 
Regardless of your size, KonaKart will provide a powerful solution that should cover most, if not all of your 
requirements, delivering unparalleled price / performance.

One of the differentiation factors of KonaKart is that all functionality is available through a set of APIs (POJO, 
JSON, SOAP, RMI, JavaScript). These APIs are great for integration, allowing you to seamlessly merge eCommerce 
functionality into existing web sites and to connect to back end systems through well defined interfaces. A common 
problem with eCommerce systems is the cost for upgrading as new versions of the eCommerce platform are released. 
KonaKart has solved this problem through the use of APIs which remain backwards compatible as new versions of 
KonaKart are released. This means that regardless of the complexity of your store-front customizations you can 
easily upgrade to the latest version; saving you time and money.

Abstract Advisory Information:
==============================
The Vulnerability Laboratory Research Team discovered a client-side cross site scripting web vulnerability in the official Konakart v7.3.0.1 CMS.


Vulnerability Disclosure Timeline:
==================================
2014-12-04:  Public Disclosure (Vulnerability Laboratory)


Discovery Status:
=================
Published


Affected Product(s):
====================
DS Data Systems (UK) Ltd.
Product: KonaKart - Content Management System (Web-Application) 7.3.0.1 (Linux, Windows & Multi OS Platform)


Exploitation Technique:
=======================
Remote


Severity Level:
===============
Medium


Technical Details & Description:
================================
A non persistent cross site scripting web vulnerability (client-side) has been discovered in the official Konakart v7.3.0.1 web-application.
The issue allows an attacker to inject own script code as payload to the application-side of the vulnerable online service function or module.

The client-side cross site scripting web vulnerability is located in the searchText values of the QuickSearch.action POST method request. 
Remote attackers are able to inject own malicious persistent script code inject in the search function POST method request. The attacker is 
able to prepare a malicious links to steal user/admin session data. The request method to inject the code is POST and the attack vector is 
located on the client-side of the vulnerable online-service application.

The security risk of the application-side web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 2.4.
Exploitation of the application-side web vulnerability requires a low privileged web-application user account and low or medium user interaction.
Successful exploitation of the vulnerabilities result in persistent phishing, session hijacking, persistent external redirect to malicious 
sources and application-side manipulation of affected or connected module context.
