SV-45718r1_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 -i '^USERCONTROL=' /etc/sysconfig/network/ifcfg* | grep -i yes If any results are returned with USERCONTROL set to yes, this is a finding.

Fix text

Edit the configuration for the user-controlled interface and change the USERCONTROL=’yes’ value to ‘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.
