CVE-2026-10872Public exploitNetwork attack vector

Authenticated command execution via VPN startup input

Published Jun 4, 2026 · Updated Jun 4, 2026

OS command injection in Shibby Tomato 1.28.0000 allows remote authenticated users to execute arbitrary commands through the Web UI. The public disclosure identifies start_vpnserver in /sbin/rc as the command-construction locus but does not name the manipulated argument or unsafe call. High-privilege Web UI access is required; successful exploitation runs attacker-chosen commands on the router without user interaction.
