SQL injection vulnerability in calendar.php in vBulletin 3.0.x allows remote attackers to execute arbitrary SQL commands via the eventid parameter. NOTE: the affected version has been disputed by the vendor. It appears that this is the same issue as CVE-2004-0036, which was fixed in 2.3.4.

Cross-site scripting (XSS) vulnerability in vBulletin 3.0.12 and 3.5.3 allows remote attackers to inject arbitrary web script or HTML via the email field, which is injected in profile.php but not sanitized in sendmsg.php.
