DON'T USE PHP-Nuke 7.6

Someone fixes a security bug and what does FB do ?
Create a bigger hole in the system Laughing

You wanna have an example ?

k here goes:
admin/modules/authors.php

Code:

global $prefix, $db, $admin_file;
if (!eregi("".$admin_file.".php", $_SERVER['PHP_SELF'])) { die ("Access Denied"); }

Now call that file thru sometihng like:

mydomain.com/admin/modules/authors.php?admin_file=authors

GOOD LUCK !!!!

Oh another example:

admin.php

normaly it loads mainfile.php first, but now it does some variable checks first.

Now my server php.ini is setup without "register_globals" so they don't exist (yet)
And it bypasses all useless security measurements.

Then mainfile.php "fakes" register_globals by defining everything (also my url constructed variables)
Then i have a lot of luck hacking around.

In addition, the code at the beginning of mainfile.php appears to let you include a mainfile.php file of your choosing. That's not the case. You can only include code that does not already exist in mainfile.php. PHP does not allow 'overloading' of functions. And what good does it do to have that code at the top? Anything you add can only be code that mainfile would use to start with.

FB did that little thing to a couple of other files as well because of the edits that NukeSentinel(tm), NSN, and other script devs use. He wants us to conform to his way of thinking again Sad

BobMarion · Posted: Thu Nov 18, 2004 3:30 am

Oh, and I've done file compares and he did not use any of CS's Patched files at all Sad

I also remember this patch being released by NSN after that long night talking with DJ:

Code:

if ($aid AND (!isset($admin) OR empty($admin)) AND $op != 'login') {
unset($aid);
unset($admin);
echo "Access denied";
die();
}

But I don't see any credits to him or me Sad

I must be a horrible hacker cuz I tried this trick on my test 7.6 site and got a 404 error.

No 'luck' either, direct access to those files isn't possible on my testsystems.

Wouldn't it be an option to define the admin file as a constant instead of using a variable? I'm not sure if that would make sense though... can you manually put a constant in a url string? I just think a constant can't be manipulated (think I've read that somewhere).

I didn't say how and when the vulnerabilities work to prevent scriptkiddies playing with it.
A real developer knows when and how they work.

MrFluffy · Posted: Thu Nov 18, 2004 10:12 am

Oh sorry, didn't want to disturb the 'real' developers with my childish comments Wink

You did mention something good about defines.

Yes defines are the only good option if it's used wisely like:

Code:

if (!defined('CPG_NUKE')) { exit; }

Besides the arguments raised against 7.6 on this topic,

, too.

Can you post what those are oprime?

oprime2001 · Posted: Thu Nov 18, 2004 1:40 pm

Sorry. I should have been more explicit. The other concerns are NOT necessarily security-specific. The concerns are more related to nukelite/FB's perceived attitude.

Chatserv: Is there going to be a patched version of 7.6? It would appear that your builds are the only ones we can trust to be secure anymore.

What a mess. What is this junk solution doing in a nice place like this?

Can we send this one back to "the Club" until it's ready for Beta?

Watch out for your blocks in 7.6 folks!

Some have:

Code:

if (eregi("block-Big_Story_of_Today.php", $_SERVER['PHP_SELF'])) {
Header("Location: index.php");
die();

While others have:

Code:

if (eregi("block-Advertising.php",$_SERVER[PHP_SELF])) {
Header("Location: ../index.php");
die();

Where is that pesky index.php file anyway?

This one is named wrong:

Code:

if (eregi("block-Last_10_Articles.php", $_SERVER['PHP_SELF'])) {
Header("Location: index.php");
die();
}

Space or no space after that comma?.. Hmmm.. I guess it doesn't matter since there a bunch of these both ways. Way to keep a standard!

Code:

if (eregi("block-Last_Referers.php",$_SERVER['PHP_SELF'])) {
Header("Location: index.php");
die();
}

It's the lemmings that amaze me. If he would just come down from his ego and open this up, the community could beta test it for him before he releases it! But it still doesn't explain why he, as the developer (and I use the term very loosely), doesn't test his stuff with all known exploits BEFORE he releases it!

I agree. I tried to defend him for a long time but its just impossible now. I work at an ISP and there is talk about banning use of all Nuke related software because of the highly insecure nature of it. I use it on my system at home and have never had a problem but I keep a close eye on all patches, etc, etc.

Raven · Posted: Thu Nov 18, 2004 11:48 pm

There are many ISP's/Hosts that are doing that. I am constantly debating the issue with my data center. I still contend that he should stop all other development and fix all known exploits. Then, he should hire waraxe to break it and then he fixes it etc...

64bitguy · Posted: Fri Nov 19, 2004 12:03 am

Users with 7.6 need to also secure the weblinks module... It's open again...

I've had this less than 20 minutes and I've found all of these? sheesh.... This is just sloppy.

chatserv · Posted: Fri Nov 19, 2004 1:16 am

A patch for it is already done but i'm sending it over to Telli and any other that wants to check it out before releasing it, there was simply way too much on my plate today with the release of phpBB 2.0.11 at the same time.

Hi all,
I have checked some parts of this version . The only thing that I can say is :
It's very buggy ! Strongly very buggy !
As a sample there is two missed form action in content / download modules.
see this :
modules/content/admin/index.php line : 186
modules/downloads/admin/index.php line : 100
Please don't install this version until a patch for it.
I'm trying do this based on Chatserv patch 2.6 .
can anyone help me in this issue and testing it ? let me know!
Have a nice Nuke Day Smile

I think that your support patching the versions - should stop with 7.6. It's getting crazy.
