Assessment Title

Rule Text

The system must not have accounts configured with blank or null passwords.

Description

Discussion Text

If an account is configured for password authentication but does not have an assigned password, it may be possible to log into the account without authentication. If the root user is configured without a password, the entire system may be compromised. For user accounts not using password authentication, the account must be configured with a password lock value instead of a blank or null value.

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

DISA STIG (Manual Reference)

Verify no accounts have blank passwords.

# logins -p

If any account with a blank password is found, this is a finding.

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

if [ ! -f "/etc/passwd" ] || [ ! -f "/etc/shadow" ]; then echo "PASS"; exit 0; fi; if grep -q '^[ ]+$' /etc/passwd || grep -q '^[ ]+$' /etc/shadow || grep -q '^$' /etc/passwd || grep -q '^$' /etc/shadow; then echo "FAIL"; exit 1; else echo "PASS"; exit 0; fi

Remediation

Remove, lock, or configure a password for any account with a blank password.
