Visale XSS vuln.

Visale XSS vuln.

###############################################
Vuln. discovered by : r0t
Date: 19 april 2006
vendor:http://www.visale.com/
affected versions: 1.0 and previous
###############################################

Vuln. Description:

Visale contains a flaw that allows a remote cross site scripting attack. This flaw exists because input passed to "keyval" paremeter in "pbpgst.cgi" and input passed to "catsubno" paremeter in "pblscg.cgi" and input passed to "listno" paremeter in "pblsmb.cgi" 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.

examples:

/pbpgst.cgi?keyval=[XSS]
/pblscg.cgi?catsubno=[XSS]
/pblsmb.cgi?cklv=0&listno=[XSS]

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