MyBulletinBoard (MyBB) contains a flaw that may allow an attacker to carry out an SQL injection attack. The issue is due to the calendar.php script not properly sanitizing user-supplied input to the 'month', 'day' or 'year' variables. This may allow an attacker to inject or manipulate SQL queries in the back-end database.
