| Description | ||||
| From a security perspective, it is important that all Automation Controller NGINX web servers are configured to use a specified IP address and port because “listening” on all IP addresses poses a vulnerability to the web server. Not confining the web server to a specified IP address and port puts all web server content at risk of access by bad actors wanting to take advantage of those resources. | ||||

As a System Administrator for each Automation Controller NGINX web server host, verify the web server is configured to use a static IP address and port.
NGINXCONF=`nginx -V 2>&1 | tr ' ' '\n' | sed -ne '/conf-path/{s/.*conf-path=\(.*\)/\1/;p}' ` ; grep '^\s*listen\s*\*\|\s*listen\s*\[.*\]\|\s*listen\s*0\.0\.0\.0\|\s*listen\s*\[.*\]|^\s*listen\s\+.*:[^[:digit:]\s]\+.*' $NGINXCONF && echo FAILED
If "FAILED" is displayed, this is a finding.
Fix Text (F-60569r902369_fix)
As a System Administrator for each Automation Controller NGINX web server host, identify the allowed and/or designated IP address(es) for the Automation Controller system.
Replace any wildcard or ranged IP address references in the NGINX configuration with IP addresses from the pool of allowed and/or designated address.
Reload the NGINX server configurations for all NGINX processes:
$ pkill -HUP nginx
