Assessment Title

Rule Text

The hosts.lpd (or equivalent) file must not have an extended ACL.

Description

Discussion Text

Excessive permissions on the hosts.lpd (or equivalent) file may permit unauthorized modification. Unauthorized modifications could disrupt access to local printers from authorized remote hosts or permit unauthorized remote access to local printers.

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:532
# The hosts.lpd (or equivalent) file must not have an extended ACL.
# Per-module read mechanism curated from static teardown of DISA's SCC tool
# (SCAP Compliance Checker) -- see the SCC Automation Reference above.

# Check to see if the /etc/cups/printers.conf file has an ACL.
# file_object (file_test)
test_1() {
  (stat -c '%A' '/etc/cups/printers.conf' | awk '{print (index($0,"+")>0)?"true":"false"}') | grep -qxF 'true'
}

if test_1; then
  echo "PASS"
else
  echo "FAIL"

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:532
path="/etc/cups/printers.conf"
if [ ! -f "$path" ]; then echo "PASS"; exit 0; fi
if [ -f "$path" ]; then acl=$(stat -f "%s" "$path"); if [ "$acl" -ne 0 ]; then echo "FAIL"; exit 1; fi; fi
echo "PASS"
exit 0

Remediation

Remove the extended ACL from the file.
# setfacl --remove-all /etc/cups/printers.conf
