Writeup — PreIgnition By Araiz Naqvi

Prepared By Araiz Naqvi.

Overview

- Difficulty: Easy
- Operating System: Linux
- Objective: Capture flag via Bruteforcing
- Tools Used: nmap, gobuster, openvpn

Nmap Scans

Let’s start with stealth scanning default ports using the -sS flag:

I now just out of curiosity to know what servers are set up maybe might come of use later.
So, I use the service scan with some default script scans:

From this I get the idea that nginx 1.14.2 is in use.

Browsing Webpage

Since port 80 is open means a webpage might be available to view.
Upon browsing:

I next check the source code which has nothing at all that might look interesting:

Bruteforcing Directories

The next option I usually think of wrt to open http pages is bruteforcing directories.
So, I use gobuster with Seclists common.txt word list:

Browsing admin.php

Upon browsing there’s a login page.
Not even making this up the first thing any hacker might think is admin:admin, and quite precisely it works XD!

  Writeup — Redeemer By Araiz Naqvi Prepared By Araiz Naqvi . Overview - Difficulty: Easy - Operating System : Linux - Objective: Capture flag via Redis - Tools Used: nmap , redis , openvpn Nmap Scans Let’s start with stealth scanning default ports using the -sS flag: Strange, nothing comes back. Let’s run an all-port stealth scan: As can be seen that port 6379 is open.  Seems like it is redis , looks like we’re about to use redis-cli . Let’s first quickly run a service and script scan: I also run a udp scan just for the sake of it: Using redis-cli Let’s use the redis-cli to logon host 10.129.229.238 : I next need to get more information using the INFO command: At the end here: This shows that there is only one db since it’s value is 0 and there are 4 keys. Let’s start by selecting this database using the SELECT : Let’s see what keys are available: Now, let’s get these variables and get all values: There’s our flag!

HTB: Nibbles Walkthrough

  Writeup — Nibbles By Araiz Naqvi Overview Difficulty: Easy - Operating System: Linux - Objective: Understand potential breaking points in nibble machine. - Tools Used: nmap , nc , whatweb , searchsploit , metasploit , gobuster , SecsList , linpeas Prepared by Araiz Naqvi Starting Enumeration with Nmap The very first step is to get an idea of the open ports and services running. To do this we will start with nmap scans: Nmap Scanning for open ports Here, two ports are open, SSH and HTTP which also show that the target is running Linux Ubuntu 2.2 version and an Apache httpd 2.4.18 server. But, before we go deeper into these open ports, let’s run an all ports TCP scan and leave it in the background cause usually it takes forever to happen. Leaving the everlong TCP all port scan in the background I actually did some banner grabbing in the meanwhile, but for consistency sake, I also immediately did a few other nmap scans to try and get as much information as p...

HTB: Cap Walkthrough

  Writeup — Cap By Araiz Naqvi Overview - Difficulty: Easy - Operating System: Linux - Objective: Capture User and Root flag. - Tools Used: nmap , ftp , sshclient , whatweb , gunicorn , wireshark , openvpn , python3 If you’re unable to view it fully due to Medium Subscriptions, you can view it at  Nmap Scanning As in most times the first step is to scan the target IP to check for open ports and service and service versions running on them: Nmap Scan As can be seen the services running are FTP , SSH and HTTP . Also, Linux seems to be running on the target. Trying Logging in FTP and SSH Let’s try to use anonymous login for FTP : FTP Login Attempt Does not allow anonymous login. Similarly, even SSH was not accepting common usernames and passwords. Clearly, I might find credentials somewhere. This is really valuable information, but let’s still get information on other aspects of the target. Let’s continue by Web Fingerprinting . Enumerating Web Fingerprint ...
