Description
Use of the .forward file poses a security risk in that sensitive data may be inadvertently transferred outside the organization. The .forward file also poses a secondary risk as it can be used to execute commands that may perform unintended actions.
ℹ️ Check
The root role is required.
# for dir in \
`logins -ox | awk -F: '($8 == "PS") { print $6 }'`; do
ls -l ${dir}/.forward 2>/dev/null
done
If output is produced, this is a finding.
✔️ Fix
The root role is required.
Remove any .forward files that are found.
# pfexec rm [filename]
