DESCRIPTION:
Thomas Pollet has discovered a vulnerability in Limbo, which can be
exploited by malicious people to conduct script insertion attacks.

Input passed to the message field in the Contact Form isn't properly
sanitised before being returned to the user. This can be exploited to
execute arbitrary HTML and JavaScript code in the administrator's
browser session in context of an affected website when a malicious
message is viewed by the administrator.

The vulnerability has been confirmed in version 1.0.4.2. Other
versions may also be affected.

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