Description
Hello hackers, I hope you are doing well. We are doing Arctic from HackTheBox.
Enumeration
nmap
We start a nmap scan using the following command: sudo nmap -sC -sV -T4 {target_IP}.

We found 3 open ports, MSRPC (135, 49154) and port 8500.
Web
Let’s check port 8500 and see if it’s accessible via http.
We find a directory listing with two directories (CFIDE and cfdocs)
On te CFIDE directory we find the following.
There is an Administrator directory, let’s see what’s there.
It’s a login page for Adobe Coldfusion 8.
Searching for this version on exploit-db we find it’s vulnerable to remote code execution
Foothold
Let’s download the exploit, change the lhost variable and run it.
We got a shell.

Let’s run windows exploit suggester
