BEWARD N100 H.264 VGA IP Camera M2.1.6 File Disclosur

<html><body><p>BEWARD N100 H.264 VGA IP Camera M2.1.6 Arbitrary File Disclosure

Vendor: Beward R&amp;D Co., Ltd
Product web page: https://www.beward.net
Affected version: M2.1.6.04C014

Summary: The N100 compact color IP camera with support for a more efficient
compression format is optimized for low-speed networks, thanks to which it
transmits a real-time image over the network with minimal delays. The camera
supports the switching of the broadcast modes, and in the event of a break in
communication with the remote file storage, it can continue recording to the
microSDHC memory card. N100 is easy to install and configure, has all the
necessary arsenal for the organization of low-cost professional video surveillance
systems.

Desc: The camera suffers from an authenticated file disclosure vulnerability.
Input passed via the 'READ.filePath' parameter in fileread script is not properly
verified before being used to read files. This can be exploited to disclose
the contents of arbitrary files via absolute path or via the SendCGICMD API.

Tested on: Boa/0.94.14rc21
           Farady ARM Linux 2.6
