CVE-2025-48826Network attack vector

Authenticated code execution via submit-url format string

Published Oct 7, 2025 · Updated Oct 7, 2025

Format-string injection in PLANET WGR-500 1.3411b190912 allows remote authenticated users to execute arbitrary code through HTTP requests. formPingCmd reads submit-url from request parameters and supplies it directly as sprintf's format string, permitting attacker-controlled directives to corrupt memory. Low-privileged web-interface access is required; successful exploitation executes code on the appliance without user interaction.
