CVE-2023-33617Public exploitNetwork attack vector

Authenticated command execution via Ping input

Published May 23, 2023 · Updated Jan 31, 2025

OS command injection in Parks Fiberlink 210 firmware 2.1.14_X000 allows remote authenticated users to execute arbitrary commands. The administrative Ping form passes the target_addr value to the system ping command without neutralizing shell metacharacters, so a pipe delimiter appends an attacker-supplied command. Administrative access is required, and successful exploitation runs commands with the router web service's privileges, enabling data access, modification, or service interruption.
