Discussion

If the permissions of the "smbpasswd" file are too permissive, it may be maliciously accessed or modified, potentially resulting in the compromise of Samba accounts.

Check Content

Check the permissions of the Samba password files.

Procedure:
# ls -lL /etc/samba/passdb.tdb /etc/samba/secrets.tdb

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 /etc/samba/passdb.tdb /etc/samba/secrets.tdb
