SV-38449r1: The root account must be the only account having an UID of 0. | HP-UX 11.23 Security Technical Implementation Guide

Assessment Title

Rule Text

The root account must be the only account having an UID of 0.

Description

Discussion Text

If an account has an UID of 0, it has root authority. Multiple accounts with an UID of 0 afford more opportunity for potential intruders to compromise a privileged account.

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.

# The root account must be the only account having an UID of 0.
# Per-module read mechanism curated from static teardown of DISA's SCC tool
# (SCAP Compliance Checker) -- see the SCC Automation Reference above.

# No non-root account may have UID 0

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.hpux11:def:45
if [ ! -f "/etc/passwd" ]; then echo "PASS"; exit 0; fi
if grep -q '^root:' /etc/passwd && ! awk -F: '$3 != 0 {print $1}' /etc/passwd | grep -qx root; then echo "PASS"; exit 0; fi
echo "FAIL"; exit 1

Remediation

Remove or change the UID of accounts other than root that have UID 0.
