Overview

On Dec. 10, 2021, D-Link was aware of a vulnerability in the widely used Java logging library Apache Log4j. The vulnerability, 'Log4Shell,' was first identified by users of a popular Minecraft forum and was reported privately to the Apache Foundation by Alibaba Cloud security researchers on Nov. 24, 2021. The vulnerability can allow unauthenticated, remote code execution (RCE) on nearly any machine using Log4j. 

As soon as we were aware of the vulnerability, D-Link began a thorough investigation into the possible impact. At this time, based on the information that we have received regarding the exposure, we have found no use of the impacted Apache Log4j library versions in our business and conclude that our products, mydlink, Nuclias, and other services, and our apps are not affected by the 'Log4Shell' vulnerability.

D-Link takes 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. Please check the D-Link website for the latest updates.
