============================================================
RootPanel (All versions) SQL injection/Account takeover.
Discovery: AkaStep and CAMOUFL4G3
Vendor: http://www.rootpanel.ru/
============================================================
What is  RootPanel ?
RootPanel is professional hosting billing system for your organisation and for your 
internet-business.
It is usefull for hosting management things like:
 /vps/vds/servers and for automate domain registrations/server/hosting management 
and so on.
============================================================
Vulnerability details:
0x30

After looking into code we noticed that theris a lot fundamental dangerious some 
"implementations" exists.

Fun begins with that developers didn't used mysql_real_escape_string() function.


//_rootfuncs.php

function htmlEncode($txt)
{
  return htmlspecialchars($txt, ENT_QUOTES, "UTF-8");
}


So we can't use    single quotes (') right? 
Because they will be converted to: 

'  (single quote)    =====> wil be converted to:   '
"  (double quote)   =====> will be converted to:  "

Also notice for first view we may think that we can't use backslash to break out an SQL query syntax and control it under our conditions.

 DO WE RIGHT ABOUT stripslashes() ?
 [ YES ]         [  NO  ]     [  CANCEL  ]   [  VABSE DUR SIKDIR xD ]

http://php.net/manual/en/function.stripslashes.php


Here is what php manual says and does as needed:

==================================


Return Values

Returns a string with backslashes stripped off. (\' becomes ' and so on.) 
Double backslashes (\\) are made into a single backslash (\).


==================================


So, as input we need pass double slashes ( \\  ) to gain access to an SQL query and correspondingly control it.



0x31     Account Takeover


No need to crack passwords... 
No need waste your machines and your gold time...


Password retrieval functionality is your best Friend!
Here is how we gained immediate access to accounts of lamers and owned all of them.


//forgotpass.php
  //SNIP//
//variable $nameemail  is user input and it passed through htmlEncode() function.//

if ($do == 'request') {
if (!$nameemail) { $error = $_lang[ForgotErrorNameOrEmail]; $do='';}
else {
$r = @mysql_query("select * from users where login='$nameemail' or email='$nameemail'") or die("File: ".__FILE__."<BR>Line: ".__LINE__."<BR>MySQL Error: ".mysql_error());
if (mysql_num_rows($r) > 0) {
while ($rr = mysql_fetch_object($r)) 
{$forgotkey=generatePassword(15);

@mysql_query("update users set forgotkey='$forgotkey' where id='$rr->id'") or die("File: ".__FILE__."<BR>Line: ".__LINE__."<BR>MySQL Error: ".mysql_error());
$tpl=GetTpl('email_touser_forgot_password',$rr->lang);
$subject=$tpl[subject]; $template=$tpl[template];
if ($subject and $template) {$company_name=GetSetting('company_name');
$company_url=GetSetting('company_url');$support_email=GetSetting("support_email");
$support_url=GetSetting('support_url');

$subject = str_replace('{login}',$rr->login,$subject);
$template = str_replace('{company_name}',$company_name,$template);
$template = str_replace('{company_url}',$company_url,$template);
$template = str_replace('{support_url}',$support_url,$template);
$template = str_replace('{login}',$rr->login,$template);
$template = str_replace('{link}',$full_www_path."forgotpass.php?fkey=$forgotkey",$template);

  // EOF SNIP //





0x32 Exploitation:

1 ) Whois interesting domain.Grab registrant mail addr.
2 ) Using sql injection grab login field's data   (ur choise you can fetch mail too)
3 ) Travel to HOSTER.TLD/forgotpass.php and enter victim mail address.
Once you've submit "SEND" button new token (aka reset token) will be generated for victim account .
 *Be carefull it also will be @mailed to victim mail address.*
4 ) Using sql injection grab token from database for victim account.
5 ) Travel to : HOSTER.TLD/forgotpass.php?fkey=APPEND_TOKEN_HERE
6 ) Set new password for lamer's account and sign in using  login and new generated password.
7 ) Travel 1111

Below is one of real exploitation examples:

NOTE 1: Avoid using error based way. In most cases it may create powerfull Denial Of service against hoster.
NOTE 2: Depending on software version column counts may vary.
Fix? 0day!
