Description:
Some vulnerabilities have been reported in vBulletin, which can be exploited by malicious users to conduct script insertion attacks.

1) Input passed to the "title" parameter in calendar.php is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when a user clicks on the "Request Reminder for this Event" link when viewing a calendar entry.

2) Input passed to unknown parameters is not properly sanitised before being used. This can be exploited to insert arbitrary HTML and script code, which will be executed in a user's browser session in context of an affected site when viewing affected data.

The vulnerabilities are reported in all 3.6.x versions before 3.6.7 PL1.

Solution:
Update to version 3.6.7 PL1.
