Details

Magento is an ecommerce application. During an application penetration test Sense of Security identified multiple cross-site scripting vulnerabilities in the administrator logon, administrator password reminder and update downloader features of the Magento application. This occurred as a result of the application not properly filtering HTML tags which allowed malicious JavaScript to be embedded. When input is incorrectly validated and not properly sanitised and then displayed in a web page, attackers can trick users into viewing the web page and causing malicious code to be executed.

Please refer to the PDF version of this advisory for proof of concept code examples.
