CVE-2025-15137Network attack vector

Authenticated root command execution via NTP URL injection

Published Dec 28, 2025 · Updated Dec 28, 2025

Command injection in TRENDnet TEW-800MB firmware 1.0.1.0 allows remote authenticated users to execute arbitrary commands. In NTPSyncWithHost.cgi, sub_F934 splits attacker-controlled URL input, formats the remainder into a date -s command, and passes it to system(); its semicolon-only check leaves other shell metacharacters unfiltered. Valid management credentials or a valid CSRF token are required, and injected commands run with root privileges on the appliance.
