The H2 Database stands out. I visit and automatically login. I note the H2 Database version (1.4.199). I see a searchsploit exists for it. https://www.exploit-db.com/exploits/49384 Copying and pasting the commands, allows for remote execution.

Getting User on the box is easy and takes less than an hour. Priv esc I couldn't figure out myself. At all.

At least failing at priv esc made me install Visual Studio to compile these Windows executables on my own !! I can generate x64/x86 exploits from .sln files now. Before I was lazy and didn't really need this. But its not that hard. PrintSpoofer.exe used to work on this box, but not anymore. I compiled WSuspicious too. Offsec is pretty good at locking down unintentional priv esc routes.

The answer is a program within Program Files (x86) called PaperStream.

Lessons Learned

  1. Check the Program Files and Program Files (x86) folder for any unusual programs.
  2. Installed Visual Studio to compile code. No longer need to solely rely on Github binaries.
  3. Discovered PrintSpoofer.exe for Win 10, Win Server 2016, 2019
  4. Never seen H2 Database before. Its a Java SQL database.

To Do

  1. Try to get PrintSpoofer working on one machine.
  2. Try out SweetPotato.

Palo Alto for GNS3 CCDC Tutorial

Opening Hello fellow CCDC Competitors! Struggling to get a Palo-Alto VM? I know how you can get one! Email me at ASzampiasSWD@gmail.com. I'll tell you the steps to get a PA-VM for GNS3. Why am I giving this info to you? Wouldn't it make sense to hog the info to myself? Wouldn't my team have an advantage? There are have and have not universities when it comes to PaloAltos. I fell into the "have not" group. Our college didn't have access to PA-VMs and still doesn't. Even if PA Cybersecurity Academy is free, there is too much red tape. I can't change the outcome. I can only come up with this one solution. Another reason is Tri-C is a tryout team. I think its pretty unfair as a potential Firewall Admin I'm the only one with access. No one can challenge me unless they spend 2K for a PA-VM. It becomes a rich-person only position. I have a leftover PA-VM from 2018 I promised not to share. I couldn't share that with my challengers. But I f

Trace Labs Global Missing Persons CTF V

Trace Labs CTF V TraceLabs hosted the Global Missing Persons CTF V event on July 11, 2020. My team //synergy got 64th place out of 190 teams. Introduction This was my first Trace Labs CTF. I captained a team. The good thing about being a captain is you can control who is on the team. My rules were: Must have sock puppet accounts ready. Must have a VPN. Writing out this is a competitive team where we work the entire 6 hours. I was worried about a future team member spamming submissions and disqualifying the team. I thought my requirements would eliminate people who weren't serious. The team hit 4 members Friday evening pretty quickly. Notes My laptop was too slow for this event. My virtual machine froze and I had to restart. Restarting means I have to login to my accounts again. I'll use my desktop next time. The team used Slack and Trello. Our strategy was to research a person and rotate every hour. This strategy broke after 1 rotation. Some missin

Release of CCDC ISE Manager Website

I worked on the ISE (Inject Scoring Engine) website from 2017 to 2019. I made it to encourage teams to follow a merit-based, open admission tryout format. I identified a problem and made a solution for it. Problem: Call for Merit and Fairness on CCDC Rosters Solution: Github Project Solution: How to run a Team After Tri-C was finished with 2017 Midwest Wildcards I used httrack to grap the Inject PDF files. I didn't grap just the files, but the entire front-end code of the website. If you created the HTML and CSS of the original ISE website, tell me your name so I can give you credit! My goal was to make an almost-replica of the original. The database and back-end code is all guessing by me. I used a LAMP stack because I believe the original website is built on that. I did some fingerprinting and found the "ccdcadmin1" website was hosted on Apache and PHP. If you notice any bugs or errors let me know. If you want a feature added let me know. I will be working
