Vulnerability discussion

The Internetwork Packet Exchange (IPX) protocol is a network-layer protocol that is no longer in common use. Binding this protocol to the network stack increases the attack surface of the host. Unprivileged local processes may be able to cause SLES for vRealize to dynamically load a protocol handler by opening a socket using the protocol.

Check content

Check that the "IPX" protocol handler is prevented from dynamic loading: # grep "install ipx /bin/true" /etc/modprobe.conf /etc/modprobe.conf.local /etc/modprobe.d/* If no result is returned, this is a finding.

Fix text

Prevent the "IPX" protocol handler from dynamic loading: # echo "install ipx /bin/true" >> /etc/modprobe.conf.local

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.
