CVE-2022-50695Public exploitNetwork attack vector

Network flooding via unrestricted diagnostic scripts

Published Dec 30, 2025 · Updated Dec 30, 2025

Resource exhaustion in Kantar Media SOUND4 appliances allows remote attackers to flood arbitrary hosts with ICMP traffic. The unauthenticated ping.php, traceroute.php, and dns.php network-command scripts launch repeated ICMP requests without rate limiting or destination controls. Any network client that can reach these scripts can consume appliance network resources and direct disruptive traffic at an external host.
