SV-61057r1_rule The system must not respond to multicast echo requests.

Vulnerability discussion

Multicast echo requests can be useful for reconnaissance of systems and for denial of service attacks.

Check content

Determine if response to multicast echo requests is disabled. # ipadm show-prop -p _respond_to_echo_multicast -co current ipv4 # ipadm show-prop -p _respond_to_echo_multicast -co current ipv6 If the output of all commands is not "0", this is a finding.

Fix text

The Network Management profile is required. Disable respond to echo multi-cast for IPv4 and IPv6. # pfexec ipadm set-prop -p _respond_to_echo_multicast=0 ipv4 # pfexec ipadm set-prop -p _respond_to_echo_multicast=0 ipv6

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
