Flaws in LG Smart TVs Allow Full Device Takeover on Local Networks

Security researchers identified three chained flaws in LG smart TVs that allow an attacker on the same local network to gain complete administrative root access without needing a password. If vulnerable displays are connected to your office network, an attacker could seize full control of the device without any user interaction. LG has released a security patch to resolve the vulnerability chain.
