Vulnerability from cvelistv5 – Published: 2022-01-28 19:10 – Updated: 2025-10-21 23:15
VLAI? CISA
Summary
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->domain variable, that has the value of the domain parameter provided through the SetDdns API, is not validated properly. This would lead to an OS command injection. An attacker can send an HTTP request to trigger this vulnerability.
