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
