I hacked a ubuntu server i control using the ubuntu overlay exploit, but after getting the root shell I couldnt run any command as root but instead they run as the normal user. Does this mean an hacker cant do any harm even with this?.. My kernel version is 5.15.0-1060-gcp. Ubuntu is 20.04 foca fossa
None of the commands i tried run as root even though the shell i got was for root
