Vulnerability discussion

Some systems have the ability to bridge or switch frames (link-layer forwarding) between multiple interfaces. This can be useful in a variety of situations but, if enabled when not needed, has the potential to bypass network partitioning and security.

Check content

Ask the system administrator if network bridging software is installed on the system or the system is configured for network bridging. If network bridging software is installed or the system is configured for network bridging, this is a finding.

Fix text

Remove the network bridging software and configuration from the system.

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.
