A vulnerability in the CLI of Cisco Firepower Threat Defense (FTD) Software and Cisco FXOS Software could allow an authenticated, local attacker to execute arbitrary commands on the underlying operating system as root. You could also issue the show traffic Complete these steps in order to configure the packet capture feature on the ASA with the ASDM: 1. This example show how to capture ARP traffic: ASA# cap arp ethernet-type ? The show traffic command shows how much traffic that passes through the ASA over a given period of time. Redistribution Between Cisco EIGRP into OSPF and Vice Versa (Example), Blocking peer-to-peer using Cisco IOS NBAR - Configuration Example. Some popular routing protocols supported by Cisco routers include Routing Information Protocol (RIP), Open Shortest Path First Protocol (OSPF), Interior Gateway Routing Protocol (IGRP) and Extended Interior Gateway Routing Protocol (EIGRP), among others. For example, you want to see real-time IP traffic sent from a host 192.168.0.112 to the outside interface of your ASA firewall.

All rights reserved. Only products listed in the Vulnerable Products section of this advisory are known to be affected by this vulnerability. To successfully exploit this vulnerability, an attacker would need valid Administrator credentials. Components Used. The routing table of Router R1 shows three networks learnt via EIGRP (denoted as D) and also two directly connected routes denoted as C. For example, destination network 192.168.30.0 is learnt via EIGRP and can be reached via 10.10.10.2 from the Serial0/0/0 interface. This example show how to capture ARP traffic: ASA# cap arp ethernet-type ? This vulnerability is due to improper input validation for specific CLI commands. In this post I have gathered the most useful Cisco ASA Firewall Commands and created a Cheat Sheet list that you can download also as PDF at the end of the article. This path selection process depends on the destination IP address of the packet received and the knowledge that the Router has about reaching that destination.
