|
|
|
|
|

Vendor: MiniDVBLinux

|
Product web page: https://www.minidvblinux.de
|
|
Affected version: <=5.4
|
|
|
|
Summary: MiniDVBLinux(TM) Distribution (MLD). MLD offers a simple
|
|
way to convert a standard PC into a Multi Media Centre based on the
|
|
Video Disk Recorder (VDR) by Klaus Schmidinger. Features of this
|
|
Linux based Digital Video Recorder: Watch TV, Timer controlled
|
|
recordings, Time Shift, DVD and MP3 Replay, Setup and configuration
|
|
via browser, and a lot more. MLD strives to be as small as possible,
|
|
modular, simple. It supports numerous hardware platforms, like classic
|
|
desktops in 32/64bit and also various low power ARM systems.
|
|
|
|
Desc: The application suffers from an unauthenticated live stream
|
|
disclosure when /tpl/tv_action.sh is called and generates a snapshot
|
|
in /var/www/images/tv.jpg through the Simple VDR Protocol (SVDRP).
