As part of our ongoing commitment to security, we have uncovered potential vulnerabilities that we are proactively addressing today with a new patch (SUPEE-6285). There are no confirmed reports of attacks related to these issues to-date, but it is important that you immediately deploy the patch in order to protect your store.
This patch addresses the following security issues:
It prevents attackers from posing as an administrator to gain access to the last orders feed, which contains personally identifiable information that can then be used to obtain more sensitive information in follow-on attacks. Check to see if you have been compromised by reviewing your server logs for someone trying to reach the /rss/NEW location.
It closes a number of security gaps including cross-site scripting (XSS), cross-site request forgery (CSRF), and error path disclosure vulnerabilities.
We have created patches for both Magento Enterprise and Magento Community Editions. For Magento Enterprise Edition, a patch is available for Enterprise Edition 1.9 and later releases. For Magento Community Edition, a patch is available for Community Edition 1.4.1 to 18.104.22.168 and is part of the core code of our latest release, Community Edition 1.9.2, which is now available for download.
