In this Box we are going to examine an android appliacation (apk) , and monitroing the requests by placing a proxy we will notice a request which we can manipulate to get a remote code exection. this box has a lot of iptables rules which restrict us from getting a reverse shell in the usual way. so we will login via ssh by placing our public key at paul’s. from that we will gain root access by exploiting sudo itself.

In This VulnHub Box, we are facing a relatively an interesting vulnerability which is tab-nabbing that will help us phish the admin to get his credentials which we can use to ssh into the Box , From There we can get a reverse shell from adrian user as he is running a cron job which is a python script and we can write into it because we are in the administrators group. and for the root part we have sudo privilege on vim editor.

you can download the machine from here we have the description :

Even Admins can fall asleep on the job

it indicates that some admin will make a mistake or something but let’s Jump in and see ourselves.

In This Box we are going to enumerate the snmp port which will show user daniel with his password as a string in the output , we are going to login with ssh to him and will see there is another user matt which has the user.txt , after some enumeration we will see there is pandora fms running internally with user matt , we will port forward to exploit the vulnerable service then we will abuse a path poisoning in a custom binary for the root access

HTB Cyber Apocalypse CTF 2022 was held from the 14th of May Until the 19th of the month , and we have participated under the team 0xcha0s, we have managed to solve multiple challenges. this challenge was ranked easy

In This medium Box we are playing with JWT Tokens in specific the jku Claim Misuse , which will let us login as admin account then we will use the Unicode Encoding to read files on the system. Eventually we will find a password for user then ssh to login. for the root part we are abusing the sudo privilege on a binary which can read files on the system.

Nahamcon ctf 2022 was held from the 28th of April Until the 30th of the month , and we have participated under the team 0xcha0s. this challenge idea was pretty new to me so it is helpful to document it in this writeup
