#################################################

NukeET Contains a flaw too that allows a remote cross site scripting
attack.This flaw exists because the application does not validate
'codigo' variable upon submission to the 'catalog.php'scripts.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.

bug found by Suko , investigate and reporter by Lostmon.

##########

'codigo' variable acepts base64 url encode , if we encode for example

<script>alert()</script><h1>XSS PoW@ !!!</h1>

in base64 this is:

PHNjcmlwdD5hbGVydCgpPC9zY3JpcHQ+PGgxPlhTUyBQb1dAICEhITwvaDE+

if we aded this base64 code the alert and de tag h1 is executed with
any problem.
