Security Advisory for Turbo NAS Users

Post by QNAPJason » Fri Sep 26, 2014 9:37 pm

Dear customers,
This week there was a serious security flaw discovered for many Unix and Linux-based systems (CVE-2014-6271).
QNAP® Systems, Inc. has been looking into the recent concerns over potential Bash code injection (CVE-2014-6271) that can lead to security vulnerabilities on the Turbo NAS and other Unix/Linux-based systems. A partial solution for CVE-2014-6271 exists but may result in another security vulnerability (CVE-2014-7169). QNAP is actively working on a solution for this issue, but in the meantime encourages all Turbo NAS users to take the following immediate actions to avoid any possible exploitation of their system.

As a temporary measure until a solution is released for this issue, please ensure that the following services of the Turbo NAS are disconnected from the Internet:
Web administration
Web server
Photo Station, Music Station, File Station, and any other NAS app that uses a web-based interface

Normally the local network is not accessible from the Internet easily, users can still use their Turbo NAS safely. If users still worry about the security of their local network, they can follow the steps to disable the QTS web UI completely, and only turn it on when necessary:
Login to QTS and disable the Web Server in Applications
Login to QTS and disable the secure connection (SSL) in General Settings
Disable NAS web administration using a SSH utility (such as putty):
1. Connect to the Turbo NAS with admin username and password
2. Type the following command and hit the “Enter” key:
/etc/init.d/ stop

Note: The NAS web administration will become unavailable after taking the above steps. To restore it:
Restart the Turbo NAS, or
Manually start the web administration via SSH by typing the following command:
/etc/init.d/ start

QNAP will keep users updated with the latest information as addressing this issue. If users would like further assistance, please contact QNAP Technical Support at
