Review the CPM filter for the router receive path using the example below:

- show system security cpm-filter ip-filter entry 10

CPM IP Filter Entry

Entry Id : 10
Description : (Not Specified)
-------------------------------------------------------------------------------
Filter Entry Match Criteria :
-------------------------------------------------------------------------------
Log Id : n/a
Src. IP : 192.168.50.0/24
Src. Port : n/a
Dst. IP : n/a
Dest. Port : n/a

Dropped pkts : 0 Forwarded pkts : 0

If the CPM filter is not configured to only allow traffic to the route processor from the OOBM local area network (LAN), this is a finding.
