CVE-2026-38065Public exploitNetwork attack vector

Remote command execution via unchecked IMS APN

Published Jun 15, 2026 · Updated Jun 15, 2026

OS command injection in Tenda 5G03 firmware V05.03.02.04 (Version 1.0) allows remote attackers to execute commands via ims_apn. The action_ims_on_with_apn handler in /usr/lib/lua/luci/controller/admin/telephony.lua processes the ims_apn value without validation before OS command execution. The published network proof of concept supplies a sysauth cookie, while CISA assesses privileges as unnecessary, leaving the authentication requirement inconsistent across public evidence.
