Overview

CVE-2021-40414 is a high-severity vulnerability. It was published on January 28, 2022 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

An incorrect default permission vulnerability exists in the cgiserver.cgi cgi_check_ability functionality of reolink RLC-410W v3.0.0.136_20121102. The SetMdAlarm API sets the movement detection parameters, giving the ability to set the sensitivity of the camera per a range of hours, and which of the camera spaces to ignore when considering movement detection. Because in cgi_check_ability the SetMdAlarm API does not have a specific case, the user permission will default to 7. This will give non-administrative users the possibility to change the movement detection parameters.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
