What to do

  1. Check whether you run it. Look for Multiple NAS Devices in your asset inventory, including appliances and cloud images. Stack check lists every exploited D-Link CVE at once.
  2. Apply the fix. This vulnerability affects legacy D-Link products. All associated hardware revisions have reached their end-of-life (EOL) or end-of-service (EOS) life cycle and should be retired and replaced per vendor instructions.
  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 4 Apr 2024.
  4. Get told next time. Email alerts when CISA adds a CVE for D-Link.
