"The Apache JServ Protocol is a binary protocol that can proxy inbound requests from a web server through to an application server that sits behind the web server."

    We kick off with an Nmap scan and we find port 8009 open:

    The description states:  "This boot to root VM is designed for testing your pentesting skills and concepts. It consists of some well known things but it encourages you to use the functionalities rather than vulnerabilities of target."

    I believe this is the same author as the Tomcat server I just wrote up this week.  Again, there's a certain style as to how the author builds boxes and I like it.  The point here is that finding mistakes and abusing functionality is very common versus say a zero day or a publicly known exploit, in my opinion. 

    We kick off with Nmap:

    This is most definitely a blast from the past.  I found some site that had a list of "must-do" HTB boxes and Jeeves was listed.  I don't have a folder named Jeeves on my machine which means it's never crossed my path.  There's a bit of irony here that made this much easier than perhaps it would have been because when we discover our entry, it's something that was unfamiliar to me some time ago.  I'd heard so much about this platform, I decided to investigate it and I'd written an entire post about it which I'll reference shortly.  Moving on...

    The description states: "Welcome to 'My Tomcat Host'.  This boot to root VM is designed for testing your basic enumeration skills and concepts."

    This is definitely a beginner box but as always, if you haven't played with the technology, it's new and could therefore be confusing. What I like about this box is that it sticks with the theme. 

    We kick off with Nmap:

    I'd heard about this some time ago and it was one of those things that I wanted to try.  Basically, the idea is that you base64 encode commands and you input the commands as TXT records in DNS.  Then you call those records, decode the payload, and execute it.  Honestly, this would have taken seconds on a Linux machine but it's more like the target would be Windows so I went with PowerShell.  I'm having a love-hate relationship with PowerShell and this, as always, is not elegant but it is functional.
