Description Philipp Hahn

2020-05-07 08:40:43 CEST

Running network facing services needlessly as user "root" is a CWE-272 violation of the "Principle of least privilege".

# ps u $(pgrep -f /usr/sbin/univention-directory-notifier)
USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
root      6457  0.0  0.5 144108  5984 ?        S    Mai05   0:00 /usr/sbin/univention-directory-notifier -d 1 -v 3 -F

Nevertheless the service should not run as user "root" but use a dedicated local user account.
