SV-64443r1_rule Network interfaces must not be configured to allow user control.

Vulnerability discussion

Configuration of network interfaces should be limited to privileged users. Manipulation of network interfaces may result in a Denial of Service or bypass of network security mechanisms.

Check content

Check the system for user-controlled network interfaces. # grep -l '^USERCTL=yes' /etc/sysconfig/network-scripts/ifcfg* If any results are returned, this is a finding.

Fix text

Edit the configuration for the user-controlled interface and remove the "USERCTL=yes" configuration line or set to "USERCTL=no".

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
