CVE-2021-40408

An OS command injection vulnerability exists in the device network settings functionality of reolink RLC-410W v3.0.0.136_20121102. At [1] or [2], based on DDNS type, the ddns->username variable, that has the value of the userName parameter provided through the SetDdns API, is not validated properly. This would lead to an OS command injection.
