CVE-2026-38064Public exploitNetwork attack vector

OS command execution via unchecked dialNumber input

Published Jun 15, 2026 · Updated Jun 15, 2026

OS command injection in Tenda 5G03 V05.03.02.04 (Version 1.0) allows remote attackers to execute commands via dialNumber. In /usr/lib/lua/luci/controller/admin/telephony.lua, action_dial_call accepts the parameter without validation, allowing shell metacharacters to append an attacker-selected command. The published request supplies a sysauth session cookie, although CISA-ADP scores the flaw as requiring no privileges; practical pre-auth reachability remains unresolved.
