CVE-2026-38062Public exploitNetwork attack vector

Authenticated command execution via unvalidated ratMode value

Published Jun 15, 2026 · Updated Jun 15, 2026

Command injection in Tenda 5G03 V05.03.02.04 allows remote authenticated users to execute OS commands via a crafted ratMode value. In /usr/lib/lua/luci/controller/admin/telephony.lua, action_set_rat_mode inserts ratMode into a quoted mipc_wan_cli command without validating or escaping shell metacharacters. A valid sysauth session cookie is required by the published request, and injected commands execute with the web-management process's privileges.
