MyBulletinBoard is a freely available forum package developed in PHP and MYSQL. MyBulletinBoard version 1.2.10 and earlier versions could allow a remote attacker to execute arbitrary commands, caused by improper validation of user-supplied input passed to the 'sortby' parameter of the 'forumdisplay.php' script before being used in an eval() function call. A remote attacker could exploit this vulnerability to inject and execute arbitrary commands with the privileges of the web server. In addition, the installed version might be vulnerable to an SQL injection vulnerability in the 'moderation.php' script and to a command execution vulnerability the 'search.php' script.
