Discussion

Excessive permissions allow unauthorized access to user files.

Check Content

Check the contents of user home directories for files with extended ACLs.
# cut -d : -f 6 /etc/passwd | xargs -n1 -IDIR ls -alLR DIR
If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding.

Fix Text

Remove the extended ACL from the file.
# setfacl --remove-all <user file with extended ACL>
