Vulnerability discussion

Proxy Neighbor Discovery Protocol (NDP) allows a system to respond to NDP requests on one interface on behalf of hosts connected to another interface. If this function is enabled when not required, addressing information may be leaked between the attached network segments.

Check content

Determine if any non-local published NDP entries exist on the system. # ndp -a If any NDP entries contain a flag of P, they are non-local published entries, and this is a finding.

Fix text

Remove non-local published NDP entries from the system. # ndp -d Check system startup scripts for commands publishing NDP entries (such as "ndp -s pub") and remove them.

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.
