CVE-2025-7154Public exploitNetwork attack vector

Authenticated command execution via unsanitized Hostname

Published Jul 8, 2025 · Updated Jul 8, 2025

OS command injection in TOTOLINK N200RE builds 9.3.5u.6095_B20200916 and 9.3.5u.6139_B20201216 allows remote authenticated users to run commands. The setOpModeCfg path reaches sub_41A0F8, which passes a nonempty hostName value containing shell metacharacters to doSystem without neutralization. Low-privileged access to the network management CGI is required, after which injected commands execute in the router firmware context.
