漏洞存在于ask/search.php文件，以下是漏洞代码：

if($keywords)
{
$where .= " AND title LIKE '%$keywords%'";
}
$infos = $ask->listinfo($where, 'askid DESC', $page, 20);
下面我们来看看listinfo()过程的代码：

function listinfo($where = '', $order = '', $page = 1, $pagesize = 50)
{
if($where) $where = " Where $where";
if($order) $order = " orDER BY $order";
$page = max(intval($page), 1);
$offset = $pagesize*($page-1);
$limit = " LIMIT $offset, $pagesize";
$r = $this->db->get_one("Select count(*) as number FROM $this->table $where");

Oh yeah！！注射漏洞就这么产生了，以下是测试语句：
