DESCRIPTION:
August Christopher has reported a vulnerability in MyBulletinBoard
(MyBB), which can be exploited by malicious people to conduct script
insertion attacks.

Input passed to the "website" field when updating the user profile
isn't properly sanitised before being used. This can be exploited to
inject arbitrary HTML and script code, which will get executed in a
user's browser session in context of an affected site when the
malicious user data is viewed.

The vulnerability has been reported in version 1.0 RC 4. Other
versions may also be affected.

SOLUTION:
Edit the source code to ensure that input is properly sanitised.
