Summary
The Reolink RLC-410W network camera firmware contains an OS command injection flaw in its network settings handling, specifically in how the dynamic DNS domain value is processed. A remote attacker could exploit this by sending crafted HTTP requests, potentially allowing arbitrary operating system commands to run on the device.

Read the original description
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.

Questions about CVE-2021-40407
What does this mean?
The device's network settings code builds an operating system command using the DDNS domain value without filtering it. A specially-crafted HTTP request can therefore make the device run arbitrary commands.Source: talosintelligence.com
Am I affected, and how do I check?
The listed version is Reolink RLC-410W v3.0.0.136_20121102, and the problem is in the device network settings functionality, specifically the DDNS settings set through the SetDdns API. To check, compare the firmware version shown in the camera's system information with this build string.Source: talosintelligence.com
What should I do about it?
The facts do not name a fixed version, so no specific upgrade target can be given. Check the vendor's site for a firmware update newer than v3.0.0.136_20121102.Source: talosintelligence.com
Is it being exploited?
Yes. CISA added it to its Known Exploited Vulnerabilities catalog on 2024-12-18, which means it has evidence of attacks. No public exploit code is tracked.Source: cisa.gov, cve.now feed data
What if there's no patch?
The facts do not include a workaround. Limiting access to the device's HTTP interface on the network is a general step that reduces exposure while no fix is available.Source: talosintelligence.com
