Vulnerability Discussion

Automation Controller NGINX web servers may host too many applications. Each application will need certain system resources and privileged operations to operate correctly. The Automation Controller NGINX web servers must be configured to contain and control the applications and protect the system resources and privileged operations from those not needed by the application for operation.

Not limiting the application will exacerbate the potential harm a compromised application could cause to a system.

Check

As a system administrator for each Automation Controller NGINX web server host, check if SELinux is enabled in enforcing mode:

getenforce | grep Enforcing >/dev/null || echo FAILED

If "FAILED" is displayed, this is a finding.

Fix

As a system administrator for each Automation Controller NGINX web server host, place the server in SELinux enforcing mode:

setenforce 1
