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. 

Critical security flaws impacting LG devices could be exploited to compromise user devices, leading to device hijacking and data theft, researchers have discovered. Researchers from Check Point disclosed two vulnerabilities which "can be used to elevate privileges on LG mobile devices to attack them remotely."

The vulnerabilities are unique to LG devices. In 2016, according to comScore, LG accounted for a 28.5 percent share in the smartphone market in the United States, settling behind Apple and Samsung. Check Point mobile security researcher said the first security weakness was discovered in LG's privileged service.
