Command injection in Tenda G103 1.0.0.5 setting handler allows high-privilege remote attackers to execute arbitrary commands via manipulation of multiple GPON authentication parameters (authLoid, authLoidPassword, authPassword, authSerialNo, authType, oltType, usVlanId, usVlanPriority) in the gpon.lua component. Publicly available exploit code exists, though the CVSS:3.1/AV:N/AC:L/PR:H vector indicates attacks require high administrative privileges and deliver limited impact (confidentiality, integrity, availability each L). This is a realistic but constrained threat: exploitation requires authenticated admin-level access to a device already on the network.
