Help me secure this code?

Aaron · 12-22-2007, 02:01 AM

Okay, this is lengthy, So bear with me. I got this code from a friend, and he got it for free from top-dog, and they don't offer support or even have a site...

Anyway, if you knew a better script that I could use (I would prefer to just make this more secure) I would be happy to use it.

Uhh... getting to the point... I would appreciate it if you would help me make this secure (regex would work fine, I just really don't even know how this thing works) whether it be giving me the secure code and telling me what you did or telling me how to secure it. Ugh, I am tired... I hope you can understand this.

PHP Code:

    INSTALLATION
    SEE THE INSTALLATION.TXT FILE
    
    VERSION 3.1.1 2004-03-10
    Added some TLD's and made changes to renamed whois servers


    VERSION 3.1 2003-12-28
    Implemented better error handing messages to be printed right into the template
    Implemented support to the server less .co.za domain using both socket and curl
    based functions to query the co.za domain zone
    Rewrite in the core to use a multi dimensional array for the server definitions
    thanks to [  ] for pointing this out this eliminates the variable definitions
    for all tlds and also the if block that supported the old decision structure
    Implemented support for checking of all the supported domains at a go although
    it slows performance a bit
    

    VERSION 3  2003- 05 -20
    THIS UPGRADED TO SUPPORT GLOBALS OF SERVERS
    BETTER DISPLAY IN THE TEMPLATE
    UPDATES TO .ORG DOMAIN WHOIS NOW TRANSFERED TO whois.publicinterestregistry.net
    THANKS TO CHRIS graphic@ev1.net FOR POINTING OUT THE CHANGE TO ME SHOULD YOU FIND
    A PARTICULAR WHOIS SERVER NOT WORKING PLEASE POST THAT ON THE FORUM FOR ME TO
    MAKE GLOBAL CHANGES FOR THE BENEFIT OF EVERY ONE --

    VERSION 2
    THIS IS THE TOTALLY REWRITTEN VERSION WHICH HAS BEEN UPGRADED TO INCLUDE
    1.SUPPORT FOR THE NEW REFERAL WHOIS SYSTEM.
    2.ACCESS CONTROL TO AVOID BANDWIDTH THEFT
    3.CHECKS FOR EXISTENCE OF TEMPLATE
    4.RETURN OF FULL WHOIS DETAILS
    5.REMOVAL OF ALL INTERPRETATIONS OF MATT'S WHOIS
    6.RENAMED TO TOPDOG DOMAIN CHECK AND WHOIS SCRIPT FROM UGANDA DOMAIN CHECK AND WHOIS
    THIS TO REFLECT OVERWHELMING INTREST FROM USERS OF INTERNATIONAL TLD's

    Do not change the server definitions unless you know what you are doing should you
    require to implement new extentions then check with iana to find out the registrar
    of the extention you want then find out the address of their whois server and the
    string it returns if a record is not found. You can the create a new entry under the
    server definitions to reflect this.

For ease of reading, please change the tags to php tags rather then code

TlcAndres · 12-22-2007, 01:13 PM

PHP Code:


			
if ($_SERVER['REQUEST_METHOD'] == 'GET'){

    $domain = $_GET['domain'];

    $ext = $_GET['ext'];

    $option = $_GET['option'];

}else{

    $domain = (eregi('$^[A-Z0-9._%+=]+\.[A-Z]{2,6}$',$_POST['domain'])) ? $_POST['domain'] : 'google.com'; 

    $ext = $_POST['ext'];

    $option = ($_POST['option'] == 'check') ? $_POST['option'] : 'whois';

}



if($restrict ==1){

    check_referer();

}

Well since theres no mysql interaction, no uploads and the such, all we can do is insure that the domain is actually a domain and that the option is either of the two available options.

the former I accomplished by using the eregi() function inside a tertionary (hope I spelled it right) which is essential a very streamlined if/else statement here is an example

PHP Code:


			
$echo = (5 > 3) ? 'true' : 'false';

echo $echo;

the latter was done again with a tertionary and it checked

PHP Code:


			
$_POST['domain']

to see if it's 'check' if it is, then we leave the $_POST variable alone, if it's not then it's set to whois

Aaron · 12-22-2007, 06:48 PM

It doesn't handle the right domain with the code you gave me though, it just handles 'google.com'. '.com', and the variable $domain doesn't really work :/.

TlcAndres · 12-22-2007, 07:04 PM

hm, well I tried it and be damned the domain bit didn't work, but I kept changing my regex and eregi wouldn't spit out that I'm right so I changed to preg_match() and use a different regex and got it I'll leave it to you to edit it

PHP Code:


			
preg_match('/[a-zA-Z0-9]\\.[a-zA-Z]{2,6}/Us',$_POST['domain'])

Salathe · 12-23-2007, 12:03 AM

I know that in the grand scheme of things this post isn't much help, but the regular expression used in the post immediately preceeding this reply really isn't much use. All it does is match a string containing a single alphanumeric character, followed by a dot, followed by between two and six letters (inclusive).

"Domains" (strings) which will be accepted by that expression include:

this_is_not_a_real_or_valid_domain.com
These are just a couple of sentences.Without a space between them!
A.Hitchcock, is a strange domain name.

The bold parts would be what actually matched the pattern.

TlcAndres · 12-23-2007, 01:27 PM

No it helps, I just need to rethink my regex. thanks salathe

on second thought, he could just use gethostbyname()..

(gethostbyname($domain) !== $domain) ? $domain : 'google.com';

topdog · 01-26-2008, 08:23 AM

Hi all,

I actually still support the code and just released an update, although i am going to convert it into an OO class.

And YES i do have a website. [Topdog.za.net]

So drop me a patch if you make security enhancements such that i can commit to mainstream

Wildhoney · 01-26-2008, 09:55 AM

Welcome Topdog

It's definitely good to see you still supporting your old code!

I want to search all TLD and UK domains in one go. Can I do that with this?

Village Idiot · 06-25-2009, 01:17 AM

This thread is almost a year and a half old.

Wildhoney · 06-25-2009, 01:32 AM

What are you wanting to do exactly, Xdam? Search all TLDs for information relating to a domain?

xdam · 06-25-2009, 07:21 AM

I just want to check the availability of all domain extensions in one search.

There are many dozens of top level domains which you would want to look through, perhaps more than you realize. To look through all of them at the same time not only would require multiple searches (one for each domain extension). Not to mention wasted time gathering results that aren't necessarily wanted (how many times have you wanted to search for blah.nf?). If you want to look through all 250+ top level domains in real time, then be my guest. I wouldn't advise it though.

xdam · 06-25-2009, 10:32 AM

Thanks for the reply. I could always use another script I guess.

When I said TLD (Top Level Domains) I was talking about just .com, .net, .org, .info and .biz and then UK country specific domains.

Salathe · 06-25-2009, 10:54 AM

If you're only looking for com/net/org/info/biz/*.uk then the script in this thread should suffice. Try it and see.

Hi, this script only searches one extension at a time. I want to search them all in one go. It doesn't matter, i'll sort it.
