Nothing fancy here, just some common port opened. Let’s start enumeration with FTP.
We can see in nmap scan that FTP allowed anonymous login and there is a
todo.txt.Let’s read that:
We can see that there seem to be 2 users named
mike. Also there might be some rabbit holes. Another thing we know is that there is
wordpress somewhere there.
When we move on to the website we can see default apache page so I directly ran gobuster.
I found nothing on the wordpress. @4nqr34z told me to
look in the plain sight and that’s when I found something on the default page of Apache2.
We need to visit
index.htnl and not
n in place of
m). When we visit that page we can see a gif
if we click on that gif we’ll be taken to an
I decided to upload a
php file to see if that is restricted or not.
When I did that I was directed to
/upload.php and there I noticed it said
File is an image - image/gif. when it was actually not, meaning this
upload could be a rabbit hole.
I decided to checkout the source of the page and there I found a comment.
Since it’s a base64 we can decode it using the base64 command. I did
➜ http -b http://192.168.56.138/748AD6CCD32E4E52718445BB1CADC01EB08A0DF6/upload.php | tr -dc 'a-zA-Z0-9' | base64 -d 2>/dev/null
This will give us the decoded string i.e
so-dev-wordpress. This could mean that we need to visit this
When I opened
IP/so-dev-wordpress I got the similar looking WP. I started to look around but couldn’t find anything special there. Then I decided to do dictionary attack on the
admin login account. And that’s when I found the admin password.
Once I was in the WP I directly went to edit the
Theme and in
404.php pasted my reverse shell code and updated it file.
And then I triggered the reverse shell by running:
➜ http http://192.168.56.138/so-dev-wordpress/wp-content/themes/twentytwenty/404.php
http is a tool know as
And that will give us a reverse shell.
Horizontal Privilege Escalation
Since we are in the system we can download our enumeration script and start enumerating the system.
Enumeration script didn’t find anything special. So I decided to do it manually.
/var/mail I found two email for
Both of them refers to
mikes password and the
mike email even says that he uses the same password as
wordpress so I decided to see if I can dump database for the wordpress.
First I read the
mysql password for
I read the
sodevwp_users table from the
sodevwp database and that had password hash
select * from sodevwp_users;
I copied the
mike hash to a file and used
john the ripper to crack the hash.
john --wordlist=rockyou.txt hash.txt
Now we can use this password to become
mike I started to look around for a way to become
joe but coudn’t find anything. Then @theart42 told me to look at the
/etc/passwd. When I read that file I found out that there was a hint infront of
So I decided to find files with hypen in them and I ran
mike@inplainsight:/tmp$ find / -type f -name *-* 2>/dev/null
And it gave me the following output:
And then I read the
/etc/passwd- which had the joe’s password.
joe:SmashMouthNoThanks I su’ed joe
Vertical Privilege Escalation
I found a file name
/home/joe and it said
I started to look around but couldn’t find anything and then in the SUID section I noticed that there was a SUID named
bwrap which had a
This mean we can try to run this as
This was a pretty good machine, even though there wasn’t anything tough but still a sweet way to root. Thanks to @bzyo_ for making this machine.
