CVE-2025-1819Network attack vector

Remote command execution via unsanitized lan_ip

Published Mar 2, 2025 · Updated Mar 3, 2025

OS command injection in Tenda AC7 1200M 15.03.06.44 allows attackers to execute shell commands remotely through lan_ip. TendaTelnet passes the HTTP parameter directly into the doSystem system-command call without neutralizing shell metacharacters. Published assessments disagree on the gate: VulDB requires low privileges, while NVD identifies no authentication requirement.
