Title: PHP-Calendar Remote File Include Vulnerability

Severity: HIGH

Description:

PHP-Calendar is a Web based calendar implemented in PHP.

A remote file include vulnerability affects PHP-Calendar. This issue is due to a failure of the application to properly sanitize user-supplied input prior to using it in a PHP 'include()' function call.

The problem presents itself specifically when an attacker passes the location of a remote attacker-specified script through the 'phpc_root_path' parameter of the 'calendar.php' and 'setup.php' scripts.

An attacker may leverage this issue to execute arbitrary server-side script code on an affected computer with the privileges of the Web server process. This will facilitate unauthorized access.
