Webmatic 3.0.3 Multiple cross-site scripting
Vendor URL:http://www.valarsoft.com/
Advisore: http://lostmon.blogspot.com/2010/03/webmatic-303-multiple-crosssite.html
Vendor notified: YES
#################################

Webmatic contains a flaw that allows a remote cross site
scripting attack. This flaw exists because the application
does not validate multiple variables and form fields upon
submission to the 'index.php' script. 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.
