Vulnerability:
|
|
~~~~~~~~~~~~~~
|
|
|
|
I found vulnerability in script view.php
|
|
--------------------------view.php-----------------------------------
|
|
....
|
|
<?
|
|
...
|
|
$newfic=$av."checkauth".$_SESSION[inlog].".php";
|
|
include("$newfic");
|
|
include_once($av."config.php");
|
|
include_once($av."connect.php");
|
|
...
|
|
----------------------------------------------------------
|
|
|
|
Input passed to the "$av" parameter in view.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 :
|
|
|
|
portfolio/msg/view.php
|
|
portfolio/msg/inc_message.php
|
|
portfolio/msg/inc_envoi.php
|
|
portfolio/admin/incl_voir_compet.php

|
Solution:
|
|
~~~~~~~
|
|
|
|

|
|
- Turn off register_globals
