Overview

On August 25, 2022, a 3rd party security researcher reported the EAGLE PRO AI R15 hardware revision Ax with firmware version v1.06.07 with a open DNS Resolver vulnerability 

As soon as D-Link was made aware of the reported security issues, we had promptly started our investigation and began developing security patches. The 3rd party publically disclosed the issue prior to the patches being available on our standard 90 day security patch release schedule. We do not recommend security researches act in this manner as they expose end-users to further risks without patches being available from the manufacture.

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.

Report:

When placed in "Wi-Fi Access Point" Mode an attack vector can be exploited in it's Open DNS Resolver 

Not in the mode "Router" but "Access Point" (Web interface Settings Operation Mode Bridge button Save) the device still acts as a DNS proxy (53/udp and 53/tcp). Such an an Open DNS Resolver [1] is considered a security issue. For example, I deploy the device in a hotel. An attacker can use that DNS proxy to circumvent a Captive Portal of that hotel Wi-Fi. This attack is known and ready to exploit by tools existing on the Internet, like HTTP-over-SSH-over-DNS services, called DNS Tunneling [2]. With that attack scenario, I calculated a HIGH rating in CVSS 3.1.
