Overview

On April 14, 2021, a 3rd party security researcher reported the D-Link (Non-US) DWR-933 hardware revision A and B with the WPS-PIN entry mode of the above-mentioned model is vulnerable, as the devices are delivered with an easily guessable standard PIN.

As soon as D-Link was made aware of the reported security issues, we had promptly started our investigation and began developing security patches.

D-Link takes the issues of network security and user privacy very seriously. We have a dedicated task force and product management team on call to address evolving security issues and implement appropriate security measures.
