Assessment Title

Rule Text

The inetd.conf file, xinetd.conf file, and the xinetd.d directory must be group-owned by root, bin, sys, or system.

Description

Discussion Text

Failure to give ownership of sensitive files or utilities to system groups may provide unauthorized users with the potential to access sensitive information or change the system configuration possibly weakening the system's security posture.

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

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.

#!/bin/bash
# Reconstructed from oval:mil.disa.fso.rhel11:def:257
# The inetd.conf file, xinetd.conf file, and the xinetd.d directory must be group-owned by root, bin, sys, or system.
# Per-module read mechanism curated from static teardown of DISA's SCC tool
# (SCAP Compliance Checker) -- see the SCC Automation Reference above.
#
# MANUAL REVIEW REQUIRED -- the module(s) below could not be reconstructed
# into working code from curated SCC reference data, and are excluded from
# the automated result:
#   - file_object (file_test) -- check /etc/xinetd.d directory files are group-owned by root, bin, or sys: no extractor for field "group_id"

# check /etc/xinetd.conf file is group-owned by root, bin, or sys
# file_object (file_test)
test_1() {
  ( [ "$(stat -c '%g' '/etc/xinetd.conf')" -eq 0 ] ) || ( [ "$(stat -c '%g' '/etc/xinetd.conf')" -eq 1 ] ) || ( [ "$(stat -c '%g' '/etc/xinetd.conf')" -eq 3 ] )
}
# check /etc/xinetd.d directory is group-owned by root, bin, or sys
# file_object (file_test)
test_2() {
  ( [ "$(stat -c '%g' '/etc/xinetd.d')" -eq 0 ] ) || ( [ "$(stat -c '%g' '/etc/xinetd.d')" -eq 1 ] ) || ( [ "$(stat -c '%g' '/etc/xinetd.d')" -eq 3 ] )
}

if ( test_1 && test_2 ); then
  echo "PASS (automated portion only -- MANUAL REVIEW still required, see notes above)"
else
  echo "FAIL (or see MANUAL REVIEW note above)"

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.rhel11:def:257
if [ ! -f "/etc/xinetd.conf" ]; then echo "PASS"; exit 0; fi; [ $(stat -c "%G" "/etc/xinetd.conf") = "root" ] || [ $(stat -c "%G" "/etc/xinetd.conf") = "bin" ] || [ $(stat -c "%G" "/etc/xinetd.conf") = "sys" ] && echo "PASS" || echo "FAIL" && exit 1; if [ ! -d "/etc/xinetd.d" ]; then echo "PASS"; exit 0; fi; [ $(stat -c "%G" "/etc/xinetd.d") = "root" ] || [ $(stat -c "%G" "/etc/xinetd.d") = "bin" ] || [ $(stat -c "%G" "/etc/xinetd.d") = "sys" ] && echo "PASS" || echo "FAIL" && exit 1; for file in /etc/xinetd.d/*; do [ $(stat -c "%G" "$file") = "root" ] || [ $(stat -c "%G" "$file") = "bin" ] || [ $(stat -c "%G" "$file") = "sys" ] && echo "PASS" || echo "FAIL" && exit 1; done; echo "PASS"; exit 0

Remediation

Change the group-owner of the xinetd configuration files and directories.

Procedure:
# chgrp -R root /etc/xinetd.conf /etc/xinetd.d
