Multiple cross-site scripting (XSS) vulnerabilities in usercp.php in MyBulletinBoard (MyBB) 1.02 allow remote attackers to inject arbitrary web script or HTML via the (1) notepad parameter in a notepad action and (2) signature parameter in an editsig action. NOTE: These are different attack vectors, and probably a different vulnerability, than CVE-2006-0218 and CVE-2006-0219.

The original distribution of MyBulletinBoard (MyBB) to update from older versions to 1.0.2 omits or includes older versions of certain critical files, which allows attackers to conduct (1) SQL injection attacks via an attachment name that is not properly handled by inc/functions_upload.php (CVE-2005-4602), and possibly (2) other attacks related to threadmode in usercp.php.
