CVE-2023-32632Public exploitNetwork attack vector

Unauthenticated command execution via unescaped ping input

Published Oct 11, 2023 · Updated Nov 4, 2025

Command injection in Yifan YF325 1.0_20221108 allows remote attackers to execute arbitrary shell commands through its web interface. The unauthenticated Diagnostic request path passes the ping_ip parameter to eval inside diag_ping_start without validation or shell escaping. Network access to the management web server is sufficient; injected commands run with the router web service's privileges.
