Test ID:1.3.6.1.4.1.25623.1.0.10113
Category:Firewalls
Title:icmp netmask request
Summary:NOSUMMARY
Description:Description:

The remote host answered to an ICMP_MASKREQ query and sent us its
netmask .

An attacker can use this information to understand how your network is set up
and how the routing is done. This may help him to bypass your filters.

Solution : reconfigure the remote host so that it does not answer to those
requests. Set up filters that deny ICMP packets of type 17.

Risk factor : Low
