After searching through portal, one user lnorgaard have plaintext password in description field. Welcome2023!
This set of credentials allowed for login in SSH
Privilege Escalation
User have RT30000.zip file, after unzipping it inside there are memory dump and keepas database.
There was one vulnerability that allow dumping master password from memory, researcher that discovered this vuln shared a PoC:
After googling whats was dumped correctly it is some kind of dessert
So password is rødgrød med fløde. Inside keepass there is some kind of ssh key in putty format.
This can be converted to PEM key with one command as shown here:
puttygen key -O private-openssh -o root.keyThis allowed for login to root account with converted key.
