Historically, XAMPP ships with default credentials that are widely known. If a user installs XAMPP and exposes it to the internet without modification, it is trivially exploitable.

return array('severity_level' => $severity_level, 'recommendations' => $recommendations);

XAMPP bundles phpMyAdmin by default. In many default installations, this interface is accessible from the local network or, dangerously, the public internet.

if (!empty($exploits)) $severity_level = 'high'; $recommendations[] = 'Remove potential backdoors or malware';
