DESCRIPTION:
Kamil 'K3' Sienicki has discovered a vulnerability in OpenFAQ, which
can be exploited by malicious people to conduct script insertion
attacks.

Input passed to the "q" parameter in submit.php isn't properly
sanitised before being saved. This can be exploited to execute
arbitrary HTML and script code in an administrative user's browser
session in context of an affected website when a malicious question
entry is viewed.

The vulnerability has been confirmed in version 0.4.0. Other versions
may also be affected.

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