in "KonaKart Storefront Application" Enterprise Java eCommerce product

Vendor
===================
DS Data Systems (UK) Ltd.

Product

 - source: https://en.wikipedia.org/wiki/KonaKart

Affected versions
===================
This vulnerability affects versions of KonaKart Storefront Application prior to 7.3.0.0

Patch
===================
The vendor has released a XSRF fix as part of version 7.3.0.0 at
http://www.konakart.com/downloads/ver-7-3-0-0-whats-new

Reported by
===================
This issue was reported to the vendor by Christian Schneider (@cschneider4711) 
following a responsible disclosure process.

Severity
===================
Medium

Description
===================
The existing CSRF protection token was checked for every POST request
properly. When modifying the request from POST method to GET method 
all state-changing actions worked as well, but the CSRF token protection 
was no longer enforced, allowing CSRF attacks.

Escalation potential
====================
Exploitation demonstration was responsibly provided along with the vulnerability 
report to the vendor, which changed a victim's mail address (using the CSRF 
protection bypass) to an attacker-supplied mail address, allowing a successful 
reset of victim's account password by the attacker.
