I tried several MSRPC vulnerabilities on port 135 and 49154 but neither of them worked so I moved onto the port 8500.

Reading exploit 14641 got me the directory reversal exploit that reveals the password for the admin account.

Ran the password hash against the Hash Killer and got the password for the admin account.

Login as admin got me access to the task scheduler which had the ability to fetch data from a website and save the output into a location on disk.

Using MSFVenom I generated a jsp exploit to be uploaded to the server and uploaded it to the CFIDE directory of the installation. (C:\ColdFusion8\wwwroot\CFIDE\reverseshell.jsp)

User Own

This got me a reverse shell as user tolis and let me capture the user flag.

Root Own

My next target was to upgrade the current reverse TCP shell to a meterpreter shell. So I created another msfvenom payload and downloaded it on the target machine and got meterpreter shell.

This got me a meterpreter shell as the same user (tolis) however, the shell I was running was a x86 shell and the box was a x64 machine so I had to upgrade the shell to a x64 shell.

I used the longer route, it could have been done better using the migrate command builtin into meterpreter shell, but anyways, got the job done.

Now I ran local exploit suggester on the box to list all the possible attack options.

Learning Outcome

I have to stop being so dependent upon metasploit for my post exploitation. Learned a way to download files using CMD line, and how to upgrade shell to x64.
