SV-38373r1: Files executed through a mail aliases file must be group-owned by root, bin, sys, or other, and must reside within a directory group-owned by root, bin, sys, or other. | HP-UX 11.23 Security Technical Implementation Guide

Assessment Title

Rule Text

Files executed through a mail aliases file must be group-owned by root, bin, sys, or other, and must reside within a directory group-owned by root, bin, sys, or other.

Description

Discussion Text

If a file executed through a mail aliases file is not group-owned by root or a system group, it may be subject to unauthorized modification. Unauthorized modification of files executed through aliases may allow unauthorized users to attain root privileges.

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.

# Files executed through a mail aliases file must be group-owned by root, bin, sys, or other, and must reside within a directory group-owned by root, bin, sys, or other.
# 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) -- alias execs growned by root,bin,sys,other: no extractor for field "group_id"
#   - file_object (file_test) -- alias exec dir growned by root,bin,sys,other: no extractor for field "group_id"

echo "MANUAL REVIEW REQUIRED -- see notes above; no part of this check could be automated"

Remediation

Change the group ownership of the file referenced from /etc/mail/aliases.
# chgrp root <file referenced from aliases>
