PrestaScan is a fork of WPScan for PrestaShop. It's under development and not finished at all.
Actually it only detects PrestaShop version and do other useless stuff. Building a full database of vulnerabilities is time consuming especially because there is no website reporting it.
If you want to help, let's talk :) !
As it's a fork of WPScan, PrestaScan needs Ruby >= 2.1.9 and RubyGems.
Just clone this repo, install needed gems and you're good to go.
git clone http://too_lazy_to_get_the_url PrestaScan
bundle install
ruby prestascan.rb --url https://prestashop_website_url
In most of the case do not follow the redirection.
PrestaShop is not detected when the base url has a 301 redirect. Just use the -f option
