Assessment Title

Rule Text

The system must not have the Calendar Manager Service Daemon (CMSD) service active.

Description

Discussion Text

The CMSD service for CDE is an unnecessary process that runs a root and increases attack vector of the system. Buffer overflow attacks against the CMSD process can potentially give access to the system.

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
# This script implements the OVAL definition: oval:mil.disa.fso.aix11:def:389

if [ ! -f "/etc/inetd.conf" ] || [ ! -s "/etc/inetd.conf" ]; then
  echo "PASS"
  exit 0
fi

if ! grep -qE "cmsd" /etc/inetd.conf; then
  echo "PASS"
  exit 0
else
  echo "FAIL"
  exit 1
fi

Remediation

Edit /etc/inetd.conf and comment out the CMSD service. 

Restart the inetd service.   
# refresh -s inetd
