icmp netmask request Vulnerability Scan
Vulnerability Scan Summary
Sends an ICMP_MASKREQ
Detailed Explanation for this Vulnerability Test
The remote host answered to an ICMP_MASKREQ query and sent us its
netmask .
A possible hacker 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.
Threat Level: Low
