SIMPLE PAGE CACHING ENGINE

5 comments:
This is a good script for grabbers and other websites where dynamic page creation causes too much overhead. The script will cache the page and store it in a database for a specific time period ( defined as lifespan i.e. last parameter of the constructor).
The cached page will be directly sent to browser and script's execution will be terminated. If no cached page is found or a new page is requested, then the script will execute as normal but will cache the page and stored it for future.
Read through comments in the top section of script for instructions related to installation and usage.

New security bug in Chipmunk forum script

4 comments:
Chipmunk forum script is still used by a few webmasters (including me) so I'm posting this new security vulnerability here and I request all the owners to patch it ASAP.

The problem lies with a SQL query which updates user's current location on forum.

Query:

UPDATE <prefix>_users SET userwhere = '$_SESSION[user] is viewing thread: $threadTitle' where username = '$_SESSION[user]'

The variable $threadTitle is actually sanitized before storing it in posts table but when it is retrieved, it regains it's original form. Now this retrieved form is used inside query without escaping which can be easily exploited.

Say original thread title was "Happy new year", the stored one would be "Happy new year" and the retrieved one would be "Happy new year".

Now suppose a notorious user has arrived and he tries follow thread title "',status='9',userwhere=userwhere--", then the stored thread title is "Hacked\',status=\'9\',userwhere=userwhere--". This is okay but when it is retrived, it regains it's original form i.e. "Hacked',status='9',userwhere=userwhere--". When this title is used in the query,
the resulting query becomes



UPDATE <prefix>_users SET userwhere = '$_SESSION[user] is viewing thread:',status='9',userwhere=userwhere--' where username = '$_SESSION[user]'

After re-arranging :

UPDATE <prefix>_users SET userwhere = '$_SESSION[user] is viewing thread: '  ,status='9' , userwhere = userwhere--

When this query is executed, all users are upgraded to a status 9 which is owner's status in Chipmunk forum. Similarly user can craft another set of query to do something else. The hacker can also extend this to inject something inside posts or forum.

How to fix it ?

It's easy! Follow the golden rule : Always sanitize a variable before placing it in a query.

// if you use mysqli
$threadTitle = $db->real_escape_string($threadTitle);
// Or if you use Mysql

$threadTitle = mysql_real_escape_string($threadTitle); 

Then proceed with the query

PS: I have not properly explain how to hack for I don't want anymore to hack anything after reading this blog post.

Don't copy my findings and tutorials.
Don't hack someone's forum based on this knowledge.
Contact me if you've issues implementing the fix.  Good luck and Enjoy!

Upgrading to PHP 5.4 on XAMPP

11 comments:
Here's a quick tutorial on how to upgrade you XAMPP installation to use latest version of PHP that is PHP version 5.4.

1. Download windows build from the official site. ( I had used this link.)

2. Extract all files from the downloaded archive to a temporary folder say php_new.

3. Make sure XAMPP / Apache is not running.

3. Go to the folder where XAMPP is installed and rename the folder XAMPP_ROOT/php to php_old

4. Now go back to our temporary folder i.e. php_new and copy all files to XAMPP_ROOT/php where XAMPP_ROOT is obviously the folder where XAMPP has been installed.

5. Enter the php folder and locate the file(s) php5apache*.dll ( Example php5apache2_2.dll )



6. Copy those files to XAMPP_ROOT/apache/modules/ depending on your version of Apache

7. Optionally delete the folders php_new and php_old

8. Start Apache again and verify that everything is working smoothly by creating a phpinfo file.


9. Don't forget to rename php.ini-production to php.ini and edit it as per your needs. ( Example: set extension_dir to XAMPP_ROOT/php/ext

10. Check Apache logs for any possible errors.

Blogger NCR UserScript

Google has recently changed the way blogspot domains work. Now if you're from Australia, you'll see blogspot.au not blogspot.com.
I was annoyed with this new changed because I was always redirected to technoslab.blogspot.in so I wrote this UserScript for myself.

What does it do ? 

This Userscript lets you always browse the original blogspot blog by automatically sending you to NCR version of that blog.

Auto Clicker - send fake hits on a link

26 comments:

I made the program this morning after getting lots of request from a friend.

Language: Java

Description: A basic program to send fake hits to a link using proxies. It fetches proxies from hidemyass.com/proxy-list/ and accepts proxy lists entered by users. It will not work if target link has Javascript or flash based user tracking mechanism. It will also not work if proxy server is dead.

License: You are free the share the program as it is, without disassembling or modifying the source or removing the credits information.

* You must have JRE installed on your PC for this program to work.

How to compile a C++ source

No comments:

*This post is in relation with previous post about Keylogger source. 
*This post is only meant for Windows users

[1]. Download Visual C++ 2010 from Microsoft's. If you're confused about what to download, just download the offline installer and install Visual C++ from inside the ISO archive.

[2]. Install and reboot. Now fire up MS VC++ ( Start>Program Files>MS VC++ express>MS VC++ Express)

[3]. Once opened, create a new Empty project and name it as "Keylogger".

[4]. You should be now having a solution explorer on the right side of Visual C++.

[5]. Now click on Keylogger under solution explorer and select "Add a new item" from the popup menu.

[6]. Select a .cpp source file and call it main.

[7] You should be able to get an empty file - main.cpp.

[8] Paste the source inside main.cpp and compile the source under Release mode. You should see the location of compiled executable in output pane of Visual C++. ( see image below, click to enlarge )




[9]. Navigate to output folder to get the compiled executable. (Kelogger.exe)

[C++] Keylogger source using SetWindowsHookEx

22 comments:
Compiled and tested on MS VC++ 2010 and WinXP.

Features
  • Fully commented source
  • Captures capital and small alphabets, numbers, symbols
  • Logs all special keys like tabs, alt, shift
  • Uses low level keyboard hook to log keys to a text file
  • Very optimized and resource friendly
  • Good for learning
To start logging, compile and execute. To stop logging press CTRL + F12

How to create a 'Share on Google plus' button

1 comment:
We have seen websites sporting a 'Share on Facebook' button but I've not stumbled across any website that let's you share something on Google plus by simply clicking a button. Like Facebook's like button, Google has provided webmasters with a +1 button but that only let's you +1 it i.e you can not post your views, opinions whiling pressing the +1 button on a website.

Now you can add a button that allows users to share your website and their opinions on Google plus. Here's how:

This is the Javascript function:

function shareOnPlus(content){
  window.open('https://m.google.com/app/plus/x/?v=compose&content='+content);
}


Now you can associate this function to onclick event of any button or image and let users share you website on G+ like they do on Facebook.

Example:

<img src="icons/google_plus.png" alt="Share on Google plus" 
onclick="shareOnPlus('Interesting article at technoslab.blogspot.com');" 
/>


Share on Google plus

How to create your own way2SMS API

9 comments:
Many web browsers available to smartphone users are unable to display way2sms.com properly and because of that people use unofficial API of Way2SMS provided by some websites like freesmz.tk. So why not create your own instead of trusting someone else and using their service ?
One afternoon, I came up with this idea and I went ahead and used my skills at PHP to develop one for myself.
I didn't place input validation checks because it was meant for personal user only.
This uses cURL extension so make sure it's available on your server before tying to run this script.

Cool signature script

No comments:
 
This is a quick fun script for people wanting to have a cool signature of different forums. This script will let users add new messages and display them on your signature dynamically. Installation is very easy, just create a file with the following code and another file named 'data.txt' in the same folder. Don't forget to chmod data.txt to 0755.

<?php
$sigs = array();
$file = 'data.txt';
$contents = file_get_contents($file);
if(!empty($contents))
    $sigs = json_decode($contents);
if(isset($_GET['add'])){
    if(isset($_GET['clr'])){
        file_put_contents($file,'');
        $sigs = array();
    }
    if(!empty($_POST['submit'])){
        $nom = $_POST['nom'];
        $msg = $_POST['msg'];
        if(!empty($nom) && !empty($msg)){

HTTP authentication via PHP

No comments:
Here's a small snippet that let's you implement htaccess style http authentication in your PHP scripts. Just define user and password and you are ready to go !

<?php
$user = "myuser";
$pass = "mypass";
if (!isset($_SERVER['PHP_AUTH_USER']) || !isset($_SERVER['PHP_AUTH_PW']) || $_SERVER['PHP_AUTH_USER']!=$user || $_SERVER['PHP_AUTH_PW']!=$pass){
    header('WWW-Authenticate: Basic realm="Enter password to access this page."');
    header('HTTP/1.0 401 Unauthorized');
	echo"You must be logged in";
    exit;
}
# Your protected contents go here !!
?>

Make sure that this code block is present in topmost of your scripts or it'll give errors and authentication will be messed up.

How to ban Gmail dot and plus trick on registration

No comments:
For gmail users, Somerandomguy@gmail.com is same as Somerandomguy+mybox@gmail.com or Somerandomguy+anything@gmail.com or Some.random.guy@gmail.com.

Although, this feature is there for user's convenience but some cunning people use this for multiple reregistration on a site usually to carry out large scale spamming.

This small snippet can be used to stop users from using plus and dot operator trick for Gmail and hence stop multiple registrations for a single email address.


  • $email = "Somerandomguy+mybox@gmail.com";
  • if(filter_var($email,FILTER_VALIDATE_EMAIL)){
  •         $email_broken = explode('@',strtolower($email));
  •         if($email_broken[1]=='gmail.com'){
  •                 $mail_without_dot = str_replace('.','',$email_broken[0]).'@'.$email_broken[1];
  •                 $mail_without_plus = preg_replace('@\+.*$@','',$email_broken[0]).'@'.$email_broken[1];
  •         }
  • }

After this, you'll have two variables $mail_without_dot and $mail_without_plus that you can use in simple SQL queries to see if a user has already used that gmail address for registering.

SMS sender - new addition to the blog

17 comments:















I just finished coding an SMS sender script. It works fine for almost all Indian network operators, I've tested. The Message delivery is instant plus you stay anonymous because SMS is not sent from your number. Most probably there are no character limits, tell me if you find a limit. 
I'm adding it to the right sidebar of the blog so that you can enjoy this service on the blog itself.
Now enjoy free anonymous SMS messaging online.
You may contact me for the script.
