I'd say this is a low risk.

Anyways. First the link in question:
modules.php?name=Your_Account&redirect=>[XSS HERE]<b&mode=>[AND HERE]<b

Although modules.php seems to point to Your_Account, I found this bug within
/forums/profiles.php.
Code:

if ( !$userdata['session_logged_in'] && $mode == 'editprofile' )
{
$header_location = ( @preg_match("/Microsoft|WebSTAR|Xitami/", $_SERVER["SERVER_SOFTWARE"]) ) ? "Refresh: 0; URL=" : "Location: ";
header($header_location . append_sid("login.$phpEx?redirect=profile.$phpEx&mode=editprofile", true));
exit;
}

@include("includes/usercp_register.php");
exit;
}
else if ( $mode == 'confirm' )
{
// Visual Confirmation
if ( $userdata['session_logged_in'] )
{
exit;
}

exit;
}
else if ( $mode == 'sendpassword' )
{
@include('includes/usercp_sendpasswd.'.$phpEx);
exit;
}
else if ( $mode == 'activate' )
{
@include('includes/usercp_activate.'.$phpEx);
exit;
}
else if ( $mode == 'email' )
{
@include('includes/usercp_email.'.$phpEx);
exit;

}
}

redirect(append_sid("index.$phpEx", true));

?>

Where to start? Mode= .. This part has 1 problem. It shows what to do if mode=editprofile, or mode=email
but it fails to address anything else..

The Redirect= problem, well, Thats one I'm still trying to pinpoint. I'm concerned that the Redirect= will be found in every area of phpNuke due to the option in Admin to force a user to register/be logged in to view the file. Thus resulting in "redirect" to the your_account (or possibly other areas)

From my finds I can't really put anything dangerous into it, IE: SQL queries, PHP Code, etc

try it on your test site, pop in the link, and then click view source
now click view source
<input type="hidden" name="redirect" value=>[XSS HERE]<b>
<input type="hidden" name="mode" value=>[AND HERE]<b>

If anyone finds a fix before me, lol, please post it here so we can all utilize it, thanks.

-Special thanks to WarAxe for his assistance. Cya's

I have done some research about this and can confirm existence of the 2 XSS cases - in variables "redirect" and "mode".
Some prominent phpnuke sites, still unpatched:

http://www.nukescripts.net
http://phpnuke.org
http://www.nukefixes.com

As XSS exists on those sites, it is obvious, that this XSS case is widespread in all the net.

How to fix? Open the "modules/Your_Account/index.php" and find this in beginning:

Code:

if (!defined('MODULE_FILE')) {
die ("You can't access this file directly...");
}

require_once("mainfile.php");
$module_name = basename(dirname(__FILE__));
get_lang($module_name);
$userpage = 1;

include("modules/$module_name/navbar.php");


Now just add some restrictive sanitizer code:

Code:

if (!defined('MODULE_FILE')) {
die ("You can't access this file directly...");
}

require_once("mainfile.php");
$module_name = basename(dirname(__FILE__));
get_lang($module_name);
$userpage = 1;

$redirect = preg_replace("/[^a-zA-Z0-9_]/",'',$_REQUEST['redirect']);
$mode = preg_replace("/[^a-zA-Z]/",'',$_REQUEST['mode']);

include("modules/$module_name/navbar.php");


This should do the trick Cool

Theoretically that should work for all of the redirect bugs , not just pages redirecting to Your Account, correct?



I'm gonna put it into my test page and give it a shot , thanks m8
