(Debian GNU/Linux)
If a user only has execute +x access to a folder they can still cd and traverse into the folder but can't use many other commands that would read the contents of the folder or files within.
drwx--x--x (owner can rwx group and rest can only execute)
Changing permissions of the file is not an option in this scenario (retired pen-testing challenge)
With this limited access, would it be possible to exfiltrate a file within or read its contents?
