Vuln. Description:

FlexChat contains a flaw that allows a remote cross site scripting
attack. This flaw exists because input passed to "username","CFTOKEN"
parameter in "index.cfm" and input passed to "CFTOKEN","CFID"
parameter in "chat.cfm" isn't properly sanitised before being returned
to the user.
This could allow a user to create a specially crafted URL that would
execute arbitrary code in a user's browser within the trust
relationship between the browser and the server, leading to a loss of
integrity.

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