Remote Code Execution 0day

Hi Friends,

Many of you already know that people try to do the things which provide them some fruits. likewise Carders trying to Exploit Shopping carts for getting into the transaction system in order to snatch people's money. Magento is a famous eCommerce CMS. this is the main target also as many of shopping sites are based on this CMS.

Here is a Recent exploit "obviously not found by me but code is mine." Which allows an attacker to change Username and Password of a site remotely. this is due to remote code Execution.

Exploit Code

and here are Results i got from Execution of the Script.

Bingoo !!

P.S: No any sites were harmed and Affected ones are reported already.

Node.JS is a Cross Platform and Runtime Environment Where one can execute javascript code, outside the Web Browser. Node.JS is Very helpful but it has a couple of Killing features which make it very dangerous and hazardous for a web application. In this tutorial we are going to discuss one of them, Command Execution in Node.JS, You Folks must know what is Command Execution but just to be sure I’d like to tell you, Command Execution Vulnerabilities Allow an Attacker to run arbitrary Commands on a System through the Vulnerable Environment. I guess its enough for introcution.

Vulnerable Code

Here is vulnerable code which demonstrates the vulnerability in node js.

Node JS Command Execution Pentesting

I’ll simply give the overview about where exactly its getting hectic. We are using exec function from child_process library, and executing parsedUrl.query.command, that is not getting filtered. Hence an attacker can execute any arbitrary commdn in order to hack into system. Let’s Save it and run it. Here is my script running.

Node JS Command Execution Pentesting

Code is working without any error, let’s try to visit the url in browser as it is listening on port 8888.

Node JS Command Execution Pentesting

Whoa, we got it working. Now its time to do some evil stuff. Let’s try to execute systeminfo, PING & Some other commands , that displays information about a computer.

Node JS Command Execution Pentesting

Node JS Command Execution Pentesting

Okay fine, as it is clear from the above POC that its working exactly fine. In this context a developer must be careful while working with Node.JS files as its kinda more hectic and Evil than other languages.

cross site tracing

Hey Folks, Let's Have a little look over Cross Site Tracing though many of you know as it is simple and easiest way but still for some of you who don't know what it is. M gonna Demonstrate.


XST (Cross Site Tracing) is combined Attack that includes HTTP TRACE METHOD and XSS Techniques. XST Allows an Attacker to see what data is being recieved at the other end of the request chain. its an old attack type that was discovered in the late of 2003. well i think its enough for now, Let's move to practical as always UrduSecurity do.

Cross Site Tracing

Well Guys First of all I need a Web server to whom I've to send the request so for this im gonna use my Localhost on port 81. and Let's Try to access it via curl.
curl -X TRACE
ok now let's see what is in response.

cross site tracing 

Umph As we can see TRACE in response so this method is allowed. Now Let's try to Add a new header if we can do it by using curl's -H option.

cross site tracing

oh ?? injected :P , so this application is prone to xss attacks via Trace method that is inshort called Cross Site Tracing. If we don't see TRACE in response and see a source page then trace method is disabled.

Hope it's Clear.

TCP Wrapper Urdu tutorial


Tcp Wrapper is a Library which provides control access and logging for the services over a server which accepts tcp connections.Most of the Linux Systems are compiled with tcp wrappers. it is a network filter ACL(access control list) that is used to filter the network access.

How TCP Wrappers Help?

  • helps in system logging
  • pattern matching access control
  • verifies the hostname
  • Protection against spoofing attacks
in these four ways tcp wrappers be helpful to us.


 Now to check if a program is compiled with tcp wrapper we use following command.
ldd /path/to/program | grep wrap
and this is gonna provide us information if the service is compiled with wrapper library. See example Below.

Urdu Hacking, UrduSecurity

as we can see that is dependency for sshd service.

Further we can use /etc/hosts.allow & /etc/hosts.deny Files to control system access. Let's Say i want to Deny all to access MySQL service and allow only Localhost. Following will be Configuration for it.

SQL injection

You can Set WildCard for it aswell to allow a list or a network. Let's say you want to allow a subnet as 192.168.*.* for SSH services.

In case of any queries Let me know. Thanks

CRLF Injection


CRLF(Carriage Return Line Feed) Injection is another Web Application Vulnerability which occures due to improper input sanitization in headers fields of a website like, Location, User-agent, Max-Age etc. This vulnerability can cause some highly risky vulnerabilities like XSS, LFI Etc.

Scene Behind CRLF

CR & LF are 2 characters that indicates the end of a line. If we type something in any text Editor and just hit the ENTER key, the Editor automatically adds CR & LF at the End of That Line. as an Example See Below:

Sometimes You might have seen them written like this \r\n, This is Exactly what is CRLF. They are written as %0d%0a also when writing in hex.


Exploiting This Vulnerability is really easy and it has targeted high profile sites like google, yahoo, microsoft Etc. Ummm Let's Take an Example Page and send a request to it Then check the http request and response via Burp suite.

Let's Save and visit this Page via browser. and intercept its http request & response via burp.


i just forwarded the request and response was something like this.

Then i manipulated the Location Header and replaced with My Localhost Address Hosted Script. See Below.


Manipulated Response:

and after clicking forward i just saw that it amazingly redirected me to my localhost script instead of google as mentioned in code. see picture.

so in this way as we can clearly see that we are able to change and manipulate the http response and request using crlf injection. we further can add our own headers and other stuff if input is not being sanitized properly. We Have also an option to Inject CRLF into headers by doing uaing following payload cache-control= private%0d%0aNew-Header:Hacked%0d%0a , soin this way by applying CRLF technique we can inject it.


Just sanitize the CRLF characters before they pass from header or also sanitize the encoding formates which let's crlf codes be injected into header.

Web Apps Pentesting


Hi, Im Muhammad Adeel From UrduSecurity, here Im gonna describe a simplest way with a simple example that how now a days hackers are tricking the Search Engine bots in order to let them think that the injected code is not a spam or they can hide it in a realistic way so that the bots think that the code is legit.


one of the best way to do the job is inserting our SPAM CODE between <div> tag with an ID or  Class. and Finally we have an option to add a Javascript to hide that DIV tag.

Trick:   We can use school level Math to Fool the engines and make a div tag Spammy, and to make ID to look different in javascript.

An Example code of the Described type of Attack Could be as follows.

Pentration testing


The idea is simple as we can see id=10 and we are accessing it through javascript by (5*2) . Malware generates a random number , lets say ('X'), and doubles the number then use it as spam <DIV> tag. Finally using the Multiplication Operator to let the Search Engine Bots think that its legit and trustworthy.

UrduSecurity Android Hacking

Hello Readers, Whats Up? Hope You all should be fine enough to read this tutorial. As in previous Article I said that i'll demonstrate that how to attack debuggable android applications. So This tutorial is about Finding and Attacking Debuggable Android Applications.

Before i start the procedure Let's collect the requirements.

and as in previous tutorial i told that Android Tamer Have all these tools so no need to be worry just start up your android tamer and if you don't have , get it now.

Checking For Vulnerable Apps

First of all we need to learn that how to check if an app is vulnerable or no. to check this we need to find either the app is debuggable or no. and how to do it? Here comes the Role of UrduSecurity

Just Download the vulnerable apk file from above given link and provide following command in your android tamer's terminal .
  • apktool d Vulnerable.apk

UrduSecurity Android Hacking

after You have done it, You have to Check AndroidManifest.xml File in order to see either the app is debuggable or no. Provide the Following Command to do that.
  • nano Vulnerable/AndroidManifest.xml
and if you see this Line there, android:debuggable="true" , viola This app is vulnerable and you can pentest it.

UrduSecurity Android Hacking

Exploiting the Vulnerable Application

Now that You've got a vulnerable android app, Let's exploit it. start up your android emulator and launch the application. your goal is to change the text Try Again into Hacked By [UrduSecurity]. but first we have to check dalvik vm ports listening on emulator. give following command.
  • adb jdwp
UrduSecurity Android Hacking

okay now we have to find on which port our Vulnerable.apk is listening which you can find again by running the app and enumeratng the ports. Let's assume the app is litening on 1180 port so let's forward to this port and attach our terminal to the app using jdb debugger.

UrduSecurity Android Hacking

Now Let's Check the classes and methods of Vulnerable.apk and as our main class is com.example.debug.MainActivity$1 so we'll be checking the Methods of that class also. see below.

UrduSecurity Android Hacking

Now We have to set a break point at onClick(android.view.View) method so that we can step through it and exploit the vulnerability by debugging the app.

  • stop in com.example.debug.MainActivity$1.onClick(android.view.View)
and then check the position where we are by entering locals in terminal. Finally we have to move next by using the keyword next. see below.

Please click on the app manually to re run the app as jdb don't provide this functionality here.

UrduSecurity Android Hacking

as in above figure , You have to step through all the steps untill you get the desired string, as we remember we have to replace Try Again with Hacked By UrduSecurity, so we found that string here. Now its time to step in the secret = "Try Again" String.

UrduSecurity Android Hacking

and finally its time to give command run , and you'll see that the app will automatically pop up our changed message that is: Hacked By [UrduSecurity]. 

UrduSecurity Android Hacking

Yahooooooo, we just hacked the app. We can do a lot of other intresting stuff like getting a remote shell on victim and so on which we'll show you in later tutorials. Hope You've enjoyed this tutorial.

android Hacking By UrduSecurity

Hello Fans, currently Busy with a lot of things and i got exams too so i'll be lazy in updating the blog, well let's start Android Hacking as its the hottest topic to be discussed these days. This tutorial is a simple walk through of Android, adb shell & other Android Pentesting tools an sources.

Let's start it , hope you'll enjoy these Articles.

Basically all the Android devices are based on Linux Platform so A HAcker Must be aware of Linux environment in order to Play with android pentesting. There is a famous Virtual Lab Named as "Android Tamer" you can directly Download it From the Below Site.

i strongly suggest this Lab because it contains almost many of the tools used for android pentesting and as Hacking also means to be in touch with open source so it contains all open source tools about android aswell and for other pentesting stuff too.

after you've got your android tamer Lab Live & working. Now its time to Start Pentesting.

Rooted android device will be always a core requirement for these tutorials.

Here Starts our first tutorial about playing with basic things in android with adb shell and getting information.

Enable USB Debugging Mode and Connect your android device with your android tamer Lab. Then do the same as shown in below screenshot.

android Hacking By UrduSecurity

if you've done it without any error , you should get a screen like this, that indicates that you got an adb shell on your android device.

android Hacking By UrduSecurity

Now that You are Connected with Your android device and Have a shell, Let's try to see the avaiable files there using "ls -l" command.

okay but till now we have only shell permissions, in order to gain root permissions we'll use 'su' command. see below.

android Hacking By UrduSecurity

Now we'll look at some files out there like gesture.key for Pattern Lock , as our pattern code is saved as salt sha-1 hashed form in gesture.key so let's look there.

android Hacking By UrduSecurity

and so on, Try to inspect it more via adb shell as we do in linux. and you'll get that where the data is stored basically and how the all stuff going ahead and working. in Next tutorial i'll Post How to debug and Find Vulnerable android applications.

Till Now if you have any problem , Let me know if i can solve.  Thanks

Hello Readers, Currently I've Described an Introduction to HttpOnly Cookies. in This Video you'll Learn How to Check a website For Http Only Flag.

incase of Queries Comment down Below the Post.

Pentesting HttpOnly Cookies

By: Adeel Chaudhary on: 03:51

Greetings Gentel Men, I'm here to Give a Simple & Understandable concept of HttpOnly Falg. First time This Technique was used by MS-IE Developers in IE-6 with XP-sp1 Version.


HttpOnly is an Additional Flag in Http Header Response named as set-cookie. and Usually using this httponly falg help in mitigating client side & server side Attacks.

Set-Cookie: name=UrduSecuirty; Max-Age=600; expires=01/04/2014;; path=/; secure; HttpOnly

Why HttpOnly

HttpOnly flag 'hypertext transfer protocol' response header is additional in, the cookie can't be accessed through consumer aspect script. As a result, a cross-site scripting flaw exists, and a user accidentally accesses a link that exploits this flaw even though the browser to a 3rd party cookie won't show.

 When we visit a web page and if We are Not able to see 'set-cookie' & 'HttpOnly' tags in response , be sure that website have no security becase its cookies can be stolen easily.

Setting HttpOnly Cookies

PHP => add this in PHP.ini
session.cookie_httponly = True
Python(CherryPy) =>add in Config File
session.cookie_httponly = True

Hope You Guys Enjoyed Reading this tutorial, its not briefly explained but its noob Friendly so that Every one can Understand. Soon I'l Post that how can we Access HttpOnly cookies Also.

Hello Friends,

After a Long time I'm Just Writing a Blog Post but Believe me its Really Fun , and Very Very Deeper Im Gonna TAke you if you really Understood What I'm gonna Describe Below.

Let's Start, Basically Data_Urls in their Base64 Encoded Form can be Used For XSS Filter Bypass. and it gets Serious While working with Firefox & Opera. When Newly Opened Documents Retain Access for Opening Page (Loading Completely). So Attacker Can Easily Trigger XSS on These Semi-Loaded Tags.

<a target=_blank href="data:text/html,");alert(1)//">Click Me</a>

Even We Can Base64_Encode This Payload. But Google-Chrome Will Block Attacker's Trick , So he Got Limited Options in His Pocket.



Fun Starts Now

 Now What if a Specific xss Filter Knows about data and try to Filter/Reject The Payload?? We Can ByPass it Still Ofcourse!! 

I Found an Intresting Way to Bypass it and You Might Like it .

data:text/html;base64UrduSecurity,[Attack-Payload] - Firefox & Safari data:text/html:;base64,[Attack-Payload]
data:text/html;base64,,[Attack-Payload] - Opera

and Here is Fully Designed Payload Ready !


This TAble Might Help You Someday.


Hope You Guys will Like This Tutorial, Leave Your Feed BAck, In case of Any Queries Let me know.
