Assessment Title

Rule Text

The smbpasswd file must be group-owned by root.

Description

Discussion Text

If the smbpasswd file is not group-owned by root, the smbpasswd file may be maliciously accessed or modified, potentially resulting in the compromise of Samba accounts.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Checks

DISA STIG (Manual Reference)

Check smbpasswd ownership.

# ls -lL /etc/sfw/private/smbpasswd

If smbpasswd is not group-owned by root, this is a finding.

SCC Automation Reference

The reconstructed evaluation script behind this rule's OVAL check(s) — every module a compound check combines, with this rule's own concrete values and DISA's SCC tool's real per-module mechanism curated from static teardown of SCC releases.

# (SCAP Compliance Checker) -- see the SCC Automation Reference above.

# Test group of /etc/sfw/private/smbpasswd is root

Assessment Script Powered by AISandbox-executed

A standalone Shell script to assess this control automatically. Review before running it in your environment.

Syntax-checked and actually executed in an isolated sandbox (not the real system this checks) — confirmed to run without errors.

#!/bin/sh
# OVAL Definition: oval:mil.disa.fso.solaris11:def:363
if [ -e /etc/sfw/private/smbpasswd ] && [ -n "$(stat -c '%G' /etc/sfw/private/smbpasswd)" ] && [ "$(stat -c '%G' /etc/sfw/private/smbpasswd)" = root ]; then echo "PASS"; exit 0; else echo "FAIL"; exit 1; fi

Remediation

Use the chgrp command to ensure the group owner of the smbpasswd file is root.

# chgrp root /etc/sfw/private/smbpasswd
