According to its banner, the version of OpenSSH running on the remote host is prior to 7.6. It is, therefore, affected by a file creation restriction bypass vulnerability related to the 'process_open' function in the file 'sftp-server.c' that allows authenticated users to create zero-length files regardless of configuration.
