GEN003608
(in versions v1 r19 through v1 r13)
Title
Proxy Address Resolution Protocol (ARP) must not be enabled on the system. (Cat II impact)
Discussion
Proxy ARP allows a system to respond to ARP 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
Check the system for non-local published ARP entries. # arp -a[n] If any entries are listed as published, this is a finding.
Fix Text
Remove any non-local published ARP entries. # arp -d <host> Check system initialization scripts for any commands configuring published ARP entries (such as "arp -s <host> <addr> pub") and remove them. # grep -n "arp \-s" /sbin/init.d/*
