CVE-2022-25390Network attack vector

Unauthenticated command execution via ping host parameter

Published Mar 18, 2022 · Updated Aug 3, 2024

Command injection in the DCN Firewall DCME-520 allows remote attackers to execute arbitrary commands through the web interface. The /system/tool/ping.php endpoint mishandles the untrusted host parameter when invoking ping, causing supplied command syntax to execute on the appliance. No authentication or user interaction is required, and successful exploitation compromises appliance data, configuration, and operation.
