WHMCS Complete Billing and Support

An update for Magento was just released to address a critical security vulnerability and it is recommended that you update as soon as possible. This update has addressed several security vulnerabilities.

Magento Critical Security Update

Following issues were addressed in the recent update:

[1] ClosedCustomer 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.

[2] ClosedRequest 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.

[3] ClosedCross-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.

[4] ClosedCross-site Scripting in Cart

The redirection link on an empty cart page uses non-validated user input, which makes it possible to use URL parameters to inject JavaScript code into the page. Cookies and other information can be sent to the attacker, who is impersonating a customer.

[5] ClosedStore 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.

[6] OpenPermissions 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.

[7] ClosedCross-site Scripting in Admin

An attacker can inject JavaScript into the title of a Widget from the Magento Admin. The code can be later executed when another administrator opens the Widget page.

The risk requires the attacker to have administrator access to the store. However, when executed, the attacker can take over other administrator accounts.

[8] ClosedCross-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.

It is highly recommended you upgrade your Magento installation to latest version immediately. For more information about this release, kindly refer following URL:
