----------------------------------------------------------------------
No authentication (login) is required to exploit this vulnerability. 
The LG DVR application is prone to a remote file disclosure vulnerability.
An attacker can exploit this vulnerability to retrieve stored files on server such as '/etc/passwd' and '/etc/shadow' by using a simple url request which made by browser.
