# phpBB 2.0.13 user level exploit

Exploit not founded by me!
Dunno who is the founder of this bug.
The original not works so i have fixed the some shit.

*Spechial thx 2 the founder of this bug*


This one goes for all phpBB versions up to 2.0.13. While applying and
testing the
patch for the autologin bug I found that phpBB2 doesn't reset the
$userdata['user_level']
variable after a failed autologin.

This is the vulvernable code in sessions.php:

Code:
f ( $user_id != ANONYMOUS )
{
$auto_login_key = $userdata['user_password'];

if ( $auto_create )
{
if ( isset($sessiondata['autologinid']) && $userdata['user_active'] )
{
// We have to login automagically
if( $sessiondata['autologinid'] === $auto_login_key )
{
// autologinid matches password
$login = 1;
$enable_autologin = 1;
}
else
{
// No match; don't login, set as anonymous user
$login = 0;
$enable_autologin = 0;
$user_id = $userdata['user_id'] = ANONYMOUS;
}
}
else
{
// Autologin is not set. Don't login, set as anonymous user
$login = 0;
$enable_autologin = 0;
$user_id = $userdata['user_id'] = ANONYMOUS;
}
}
else
{
$login = 1;
}
}
else
{
$login = 0;
$enable_autologin = 0;
}


As you can see, if autologin fails it will reset the
$userdata['user_id'] value to
ANONYMOUS, but $userdata['user_level'] stays at the value of the user
account that
failed to login.

Now phpBB only checks for the userlevel in various locations and
ignores the user_id
there. So if you manipulate the "_data" cookie to send the user_id of an admin
you can see some information that should only be visible to an admin.
Like hidden
users on the "who is online page" or email adresses from users, even if the
user disallowed that, in their profiles. Maybe you can even use some
admin functions,
I didn't check this in depth.

The cookie manipulation will only work on the first page requestet, as
the session.php
will then overwrite the user_id in it, unless you prevent the browser from
modifying the cookie of course.

The fix is quite simple, add $userdata['user_level'] = USER; after
every $userdata['user_id']
= ANONYMOUS; in session.php.

*Reported 2 PHPBB ^^
