Cross-site scripting (XSS) vulnerability in Jelsoft vBulletin 2.2.0 allows remote attackers to execute arbitrary script as other users by injecting script into a bulletin board message.

calendar.php in vBulletin before 2.2.0 allows remote attackers to execute arbitrary commands via shell metacharacters in the command parameter.

Cross-site scripting (XSS) vulnerability in memberlist.php in Jelsoft vBulletin 2.0 rc 2 through 2.2.4 allows remote attackers to steal authentication credentials by injecting script into $letterbits.

member2.php in vBulletin 2.2.9 and earlier does not properly restrict the $perpage variable to be an integer, which causes an error message to be reflected back to the user without quoting, which facilitates cross-site scripting (XSS) and possibly other attacks.

Cross-site scripting (XSS) vulnerability in global.php in Jelsoft vBulletin 2.0.0 through 2.2.8 allows remote attackers to inject arbitrary web script or HTML via the (1) $scriptpath or (2) $url variables.

index.php in Jelsoft vBulletin does not properly initialize a PHP variable that is used to store template information, which allows remote attackers to execute arbitrary PHP code via special characters in the templatecache parameter.
