该漏洞文件：ask/search_ajax.php

漏洞说明：
/ask/search_ajax.php
code:

if($q)
{
$where = " title like '%$q%' and status = 5";//没做过滤直接感染了$where
}
else
{
exit('null');
}
$infos = $ask->listinfo($where, 'askid desc', '', 10);
/ask/include/answer.class.php
code:

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_posts $where");
$number = $r['number'];
$this->pages = pages($number, $page, $pagesize);
$array = array();
$i = 1;
$result = $this->db->query("select * from $this->table_posts $where $order $limit");
while($r = $this->db->fetch_array($result))
{
$r['orderid'] = $i;
$array[] = $r;
$i++;
}
$this->number = $this->db->num_rows($result);
$this->db->free_result($result);
return $array;
}
