Assessment Procedure

Check Text

If /etc/shells exists, check the permissions of each shell referenced.
# cat /etc/shells | xargs -n1 ls -lL

Otherwise, check any shells found on the system.
# find / -name "*sh" | xargs -n1 ls -lL

If the permissions include a "+", the file has an extended ACL, this is a finding.

Implementation Procedure

Fix Text

Remove the extended ACL from the file.
# chmod A- [shell]
