A new critical Magento security patch is released to secure the platform from potential attacks. There are no confirmed reports of attacks related to these issues to-date, but it is important to immediately deploy the patch in order to protect the online stores.
This patch includes protection against the following security-related issues:
Customer Information Leak via RSS and Privilege Escalation
Improper check for authorized URL leads to customer information leak (order information, order IDs, customer name). Leaked information simplifies attack on guest Order Review, which exposes customer email, shipping and billing address. In some areas, the same underlying issue can lead to privilege escalation for Admin accounts.
Request Forgery in Magento Connect Leads to Code Execution
Cross-site request forgery in Magento Connect Manager allows an attacker to execute actions such as the installation of a remote module that leads to the execution of remote code. The attack requires a Magento store administrator, while logged in to Magento Connect Manager, to click a link that was prepared by the attacker.
Cross-site Scripting in Wishlist
This vulnerability makes it possible to include an unescaped customer name when Wishlist are sent. By manipulating the customer name, an attacker can use the store to send spoofing or phishing emails.
Cross-site Scripting in Cart
Store Path Disclosure
Directly accessing the URL of files that are related to Magento Connect produces an exception that includes the server path. The exception is generated regardless of the configuration settings that control the display of exceptions. There is a low risk of attackers gaining a sufficient understanding of the site structure to target an attack.
Permissions on Log Files too Broad
Log files are created with permission settings that are too broad, that allows them to be read or altered by another user on the same server. The risk of an internal information leak is low.
Cross-site Scripting in Admin
Cross-site Scripting in Orders RSS
The vulnerability allows an attacker to include an unescaped customer name in the New Orders RSS feed. By manipulating the customer name, an attacker can inject incorrect or malicious data into the feed, and expose the store to risk.
This patch is available for Enterprise Edition 1.9 and later releases. Before implementing this new security patch (SUPEE-6285), SUPEE-5994 patch needs to be implemented which will ensure that the patch works properly.
