Description

MyBulletinBoard (MyBB) contains a flaw that allows remote PHP code execution. This flaw exists because the application does not validate input supplied to the domecode() function upon submission to the inc/functions_post.php script. Input passed to the username field when registering isn't properly sanitized before being used in a "preg_replace" call, which can be exploited by registering with a specially crafted username and then previewing a post containing the "/slap" string.
