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.
