If you have installed a network-attached storage device manufactured by LG Electronics, you should take it down immediately, read this article carefully and then take appropriate action to protect your sensitive data.

A security researcher has revealed complete technical details of an unpatched critical remote command execution vulnerability in various LG NAS device models that could let attackers compromise vulnerable devices and steal data stored on them.

LG's Network Attached Storage (NAS) device is a dedicated file storage unit connected to a network that allows users to store and share data with multiple computers. Authorized users can also access their data remotely over the Internet.
The vulnerability has been discovered by the researcher at privacy advocate firm VPN Mentor, the same company that last month revealed severe flaws in three popular VPNs—HotSpot Shield, PureVPN, and Zenmate.
The LG NAS flaw is a pre-authenticated remote command injection vulnerability, which resides due to improper validation of the "password" parameter of the user login page for remote management, allowing remote attackers to pass arbitrary system commands through the password field.

Since LG has not yet released a fix for the issue, users of LG NAS devices are advised to ensure that their devices are not accessible via the public Internet and should be protected behind a firewall configured to allow only a trusted set of IPs to connect to the web interface.
Users are also recommended to periodically look out for any suspicious activity by checking all registered usernames and passwords on their devices.
