CVE-2025-54406Public exploitNetwork attack vector

Authenticated command execution via unchecked ping count

Published Oct 7, 2025 · Updated Oct 7, 2025

OS command injection in WGR-500 1.3411b190912 allows remote authenticated users to execute commands via crafted HTTP requests. The formPingCmd handler inserts the unvalidated counts parameter into a ping command string and passes that string to system(). Low-privilege access to the web interface is required, after which injected shell syntax executes arbitrary operating-system commands on the router.
