Vulnerability Discussion
The built-in web server is a nonessential service built into macOS and must be disabled.
Note: The built in web server service is disabled at startup by default macOS.
Check
Verify the macOS system is configured to disable the built-in web server with the following command:
/bin/launchctl print-disabled system | /usr/bin/grep -c '"org.apache.httpd" => disabled'
If the result is not "1", this is a finding.
Fix
Configure the macOS system to disable the built-in web server with the following command:
/bin/launchctl disable system/org.apache.httpd
The system may need to be restarted for the update to take effect.
