Permissions
Can you read files in the root file?
About the Challenge
We have been given an access to SSH server and then we need to read the flag in the root directory
How to Solve?
If we check the sudo configuration
There are only 1 commands that we can use, /usr/bin/vi. In this case we will be using /usr/bin/vi command to do privilege escalation (Im using GTFOBins to do privilege escalation)
And then go to /root directory and read .flag.txt to obtain the flag
