Magento is the most popular eCommerce web application in the world, with an estimated 236,000 live web sites using the Content Management System (CMS) technology[1]. Available in both paid-for “enterprise” versions and free “community” versions, it powers some of the world's most popular websites including Huawai[2], Land Rover[3] and Helly Hansen[4]. However, common eCommerce platforms make popular targets for hackers and thieves looking to steal payment card information. Like any web application, attackers will always look to exploit vulnerabilities in the underlying code before researchers can identify them and developers can fix them, but even an up-to-date and fully patched system can be left vulnerable if it is not configured properly or merchants do not follow information security best practice.
