classifiedZONE v1.2 XSS vuln.

###############################################
Vuln. discovered by : r0t
Date: 28 march 2006
vendor:http://www.fusionzone.com/applications/classifieds/
affected versions:v.1.2 and prior
###############################################

Vuln. Description:

classifiedZONE contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to "rtn" paremeter in "accountlogon.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.


example:

/accountlogon.cfm?rtn=%22%3Cscript
%3Ealert('r0t')%3C/script%3E

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