Assessment Title

Rule Text

The system must not allow users to configure .forward files.

Description

Discussion Text

Use of the .forward file poses a security risk in that sensitive data may be inadvertently transferred outside the organization. The .forward file also poses a secondary risk as it can be used to execute commands that may perform unintended actions.

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.

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

export HOME=$(getent passwd $(id -u -n):$(id -g -g) | cut -d: -f6)
for user in $(getent passwd | cut -d: -f1); do
  if [ "$user" != "root" ] && [ "$user" != "bin" ] && [ "$user" != "sys" ] && [ "$user" != "sync" ] && [ "$user" != "shutdown" ] && [ "$user" != "daemon" ]; then
    path="$HOME/$user/.forward"
    if [ -f "$path" ]; then
      echo "FAIL"
      exit 1

echo "PASS"
exit 0

Remediation

The root role is required.

Remove any .forward files that are found.
