FlexChat XSS

###############################################
Vuln. discovered by : r0t (Pridels Sec Crew)
Date: 13 may 2006
vendorlink:http://www.flexchat.net/
affected versions:v.2.0 and prior
###############################################


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.
