TLDR: Small family owned finance business woes as the “you-do-everything-now” network/sysadmin intern

Friday my boss, who is currently traveling in Vegas (hmmm), sends me an email asking me to punch a hole in our firewall so he can access our locally hosted Jira server that we use for time logging/task management.

Because of our lack of proper documentation I have to refer to my half completed network map and rely on some acrobatic cable tracing to discover that we use a SonicWall physical firewall. I then realize asking around that I don’t have access to the management interface because no one knows the password.

Using some lucky guesses and documentation I discover on a file share from four years ago, I piece together the username and password to log in only to discover that the enterprise support subscription is two years expired. The pretty and useful interface that I’m expecting has been deactivated and instead of a nice overview of firewall access rules the only thing I can access is an arcane table of network rules using abbreviated notation and five year old custom made objects representing our internal network.

An hour and a half later I have a solid understanding of SonicWallOS, its firewall rules, and our particular configuration and I’m able to direct external traffic from the right port to our internal server running Jira. I even configure a HIDS on the Jira server and throw up an iptables firewall quickly since the machine is now connected to the outside world.

After seeing how many access rules our firewall has, as a precaution I decide to run a quick nmap scan to see what our network looks like to an attacker.

The output doesn’t stop scrolling for a minute. Final count we have 38 ports wide open with a GOLDMINE of information from every web, DNS, and public server flooding my terminal. Our local domain controller has ports directly connected to the Internet. Several un-updated Windows Server 2008 machines with confidential business information have IIS 7.0 running connected directly to the internet (versions with confirmed remote code execution vulnerabilities). I’ve got my work cut out for me.

It looks like someone’s idea of allowing remote access to the office at some point was “port forward everything” instead of setting up a VPN. I learn the owners close personal friend did all their IT until 4 years ago, when the professional documentation stops. He retired and they’ve only invested in low cost students (like me!) to fill the gap. Some kid who port forwarded his home router for League at some point was like “let’s do that with production servers!”

At this point my boss emails me to see what I’ve done. I spit him back a link to use our Jira server. He sends me a reply “You haven’t logged any work in Jira, what have you been doing?”

Facepalm.
