DESCRIPTION:
imei addmimistrator has reported a vulnerability in vBulletin, which
can be exploited by malicious people to conduct script insertion
attacks.

Input passed to the "Email Address" field in the "Edit Email &
Password" functionality is not properly sanitised before being stored
in the user's profile. This can be exploited to execute arbitrary HTML
and script code in a user's browser session in context of an affected
web site when the email address of a malicious user is viewed.

Successful exploitation requires that "Enable Email features" and
"Allow Users to Email Other Member" are enabled in the
configuration.

The vulnerability has been reported in version 3.5.3. Prior versions
may also be affected.

SOLUTION:
Update to version 3.5.4.
