Local file inclusion (LFI) defence¶
Prevention
Disable dynamic file paths – Use hardcoded whitelists.
Chroot/Jail – Restrict filesystem access.
Risks
../../etc/passwd attacks
Example (PHP - Safe Include):
$allowed = ['page1.php', 'page2.php'];
if (in_array($_GET['page'], $allowed)) {
include($_GET['page']);
}
