	Subject: 	[BuHa Security] Wordpress SQL-Injection
	Date: 	May 19, 2005 11:52:58 PM EDT

| BuHa Security-Advisory #1     |    May 17th, 2005 |
| Vendor   | Wordpress                              |
| URL      |                  |
| Version  | <= Wordpress 1.5                       |
| Risk     | Moderate (SQL-Injection)               |

o Description:

WordPress is a state-of-the-art semantic personal publishing platform
with a focus on aesthetics, web standards, and usability. 

Visit for detailed information.

o SQL-Injection:

The most critical vulnerability in the 1.5 release of wordpress is an
SQL-Injection in `wp-trackback.php'. It's not easily exploitable
because you do not get a result when you inject a valid query but it's
possible to bruteforce values in the tables - for example the password

Here some details:
The parameter `tb_id' in `wp-trackback.php' is not validated correctly
and there are no quotes in the SQL-query so an attacker is able to 
insert sql commands.

$pingstatus = $wpdb->get_var("SELECT ping_status FROM $wpdb->posts
WHERE ID = $tb_id");
Example: (I converted the POST-request into a GET-request.)

$tb_id = 1 union select user_pass,0 from wp_users
$url = bla
$title = bla


By injecting this query I get following databae error:

WordPress database error:
[The used SELECT statements have a different number of columns]
SELECT ping_status FROM wp_posts WHERE ID = 1 union select 0, 
user_pass from wp_users

When I insert "1 union select user_pass from wp_users" as value for
`tb_id' I get no error message because the query was well-formed -
logical. Through the possibility to insert any sql-command it's
possible to 'reconstruct' values of the tables.

o XSS:


o Path Disclosure:


Fatal error: Call to undefined function add_filter() in
wp-content/themes/classic/comments-popup.php on line 3

o Disclosure Timeline:

17 Apr 05 - Security flaws discovered.
19 Apr 05 - Vendor contacted.
10 May 05 - Vendor released bugfixed version.
17 May 05 - Public release.

o Solution:
