D-Link announces that they are actively working to address (patch) the vulnerabilities to admin access via the web. The post also cautions against responding to unsolicited emails about security vulnerabilities that “prompt you to action” as they could be opportunistic phishing scams. They also recommend disabling wireless access to the router.
Router patches so far are available at the bottom of this D-Link post.
Patches for a separate issue involving D-Link network camera vulnerabilities are available here.
