## PORT 37652 (FTP)
|
||||
From the nmap scan we can see that anonymous ftp is enabled which means that we can login without specifying the password
|
||||
|
||||
<img src="https://i.imgur.com/NfqZ0l5.png"/>
|
||||
|
||||
from the `memo.txt` file we see that a user named `joe` has sent email with the password hash and on cracking the hash we get the password `nightmare`
|
||||
|
||||

|
||||
|
||||
## PORT 8080 (HTTP)
|
||||
|
||||
On the webserver there's apache tomcat running
|
||||
|
||||
<img src="https://i.imgur.com/g8vZnOe.png"/>
|
||||
|
||||
if we run `stegcracker` on the png image we can find a easter egg

## Foothold
|
||||
|
||||
### Un-inteded
|
||||
|
||||
We were told to find a username on the page but there wasn't any . All we know is that the username is of 5 characters so let's maybe try to brute force the username with 5 characters
|
||||
|
||||

|
||||
|
||||
<img src="https://i.imgur.com/ivawOEm.png"/>
|
||||
|
||||
We can now then get a shell as `sally`
|
||||
|
||||

|
||||
|
||||
|
||||
### Intended
|
||||
|
||||
Running `gobuster` we can find some directories
|
||||
|
||||
<img src="https://i.imgur.com/U16RHo3.png"/>
|
||||
|
||||
I tried using default creds on `/manager` , `/host-manager` but wasn't succesful so I did a recusive fuzz on `admin`
|
||||
|
||||
<img src="https://i.imgur.com/KCXq3zb.png"/>
|
||||
|
||||
This returned us `staging` so again running gobuster on this
|
||||
|
||||
<img src="https://i.imgur.com/IdCmFhl.png"/>
|
||||
|
||||
<img src="https://i.imgur.com/dnoyOYi.png"/>
|
||||
|
||||
We don't see much here but if we look at the source we can find the username `sally`
|
||||
|
||||
<img src="https://i.imgur.com/Z6O1smj.png"/>
|
||||
|
||||
We can now then get a shell through ssh
|
||||
|
||||
<img src="https://i.imgur.com/ircsnLS.png"/>
|
||||
|
||||
On doing `sudo -l` we can't do run any thing as root as other user since this user isn't in sudoers file
|
||||
|
||||
<img src="https://i.imgur.com/3WIYbmF.png"/>
|
||||
|
||||
## Privilege Escalation (Joe)
|
||||
|
||||
We can the find the user flag in `Desktop` folder of sally and can find another flag in `/home/sally/.local/share/Trash/files`
|
||||
|
||||
<img src="https://i.imgur.com/lFTq9GZ.png"/>
|
||||
|
||||
The hash can be cracked with either `hashcat` or `john` but I'll just use cracksation as I did earlier
|
||||
|
||||
<img src="https://i.imgur.com/7gi9kpi.png"/>
|
||||
|
||||
## Privilege Escalation (root)
|
||||
|
||||
Running `sudo -l` we can see that this user can run all commands
