Description

By default, many systems enable a feature called ICMP redirection, where the machine will alter its route table in response to an ICMP redirect message from any network device.

There is a risk that this feature could be used to subvert a host's routing table in order to compromise its security (e.g., tricking it into sending packets via a specific route where they may be sniffed or altered).

Solution(s)

  • generic-disable-icmp-redirect-w2k
  • generic-disable-icmp-redirect-ios
  • generic-disable-icmp-redirect-lnx
  • generic-disable-icmp-redirect-sol
  • generic-disable-icmp-redirect-general

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
