We see a wordpress installation page when I visit port 80
After directory bruteforcing we found a /filemanager directory
There’s a login page on the filemanager directory
Tried admin : admin as creds and it worked
As this is a file manage I tried to upload php shell
And it uploaded successfully
Visited shell.php and we got command execution
Taking reverse shell
Got reverse shell
We got hash value for dora user in .htusers.php
Got password for dora user
Using password to switch user to dora
Got local.txt (d76555be6f8692c623048f1367f8f1ca)
Dora user is in disk group
Using https://book.hacktricks.wiki/en/linux-hardening/privilege-escalation/interesting-groups-linux-pe/index.html for exploitation
We can access /root
And see file in it with ls
We read the hash of root user from /etc/shadow
Cracked it and got root user password
Got root
Got proof.txt (05ad63bb0ab7f4d8ef64bda86a152758)
