CVE-2021-40411

Estado: ModificadaAlta (7.2)—

An OS command injection vulnerability exists in the device network settings functionality of reolink RLC-410W v3.0.0.136_20121102. At [6] the dns_data->dns2 variable, that has the value of the dns2 parameter provided through the SetLocalLink API, is not validated properly. This would lead to an OS command injection.
