  1. Check whether you run it. Look for Multiple Routers in your asset inventory, including appliances and cloud images. Stack check lists every exploited D-Link CVE at once.
  2. Apply the fix. The impacted product is end-of-life and should be disconnected if still in use.
  3. If you can't patch today, take the affected service off the internet or restrict who can reach it, and check its logs for signs of compromise since 27 Sep 2019.
  4. Get told next time. Email alerts when CISA adds a CVE for D-Link.
