The remote web server contains a PHP script that is prone to SQL injection attacks.
The remote host is running Calendarix, a free web-based calendar application written in PHP. The version of Calendarix installed on the remote host fails to sanitize input to the 'month' and 'year' parameters of the 'calendar.php' script before using it in database queries. Provided PHP's 'magic_quotes_gpc' setting is disabled, an unauthenticated attacker can exploit these flaws to manipulate database queries, which may lead to disclosure of sensitive information, modification of data or attacks against the underlying database.
