SQL injection vulnerability in the create_session function in class_session.php in MyBB (aka MyBulletinBoard) 1.2.3 and earlier allows remote attackers to execute arbitrary SQL commands via the Client-IP HTTP header, as utilized by index.php, a related issue to CVE-2006-3775.
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.
Multiple unspecified vulnerabilities in MyBulletinBoard (MyBB) before 1.0.2 have unspecified impact and attack vectors, related to (1) admin/moderate.php, (2) admin/themes.php, (3) inc/functions.php, (4) inc/functions_upload.php, (5) printthread.php, and (6) usercp.php, and probably related to SQL injection. NOTE: it is likely that this issue subsumes CVE-2005-4602 and CVE-2005-4603. However, since the vendor advisory is vague and additional files are mentioned, is is likely that this contains at least one distinct vulnerability from CVE-2005-4602 and CVE-2005-4603.
