Who should care

Security and network teams responsible for any remaining D-Link DIR-645 routers, especially in small-office, branch, or home-office environments where the device may still provide core connectivity.

Technical summary

CISA’s KEV entry identifies CVE-2015-2051 as a remote code execution vulnerability affecting the D-Link DIR-645 Router. The KEV metadata marks the product as end-of-life and directs defenders to disconnect it if still in use. The supplied official corpus does not include a vendor patch bulletin or detailed exploit mechanics, so defensive action should focus on inventory, isolation, and replacement.

Defensive priority

Urgent. A KEV-listed remote code execution issue on an end-of-life router should be treated as an immediate remove-or-replace item.

Recommended defensive actions

  • Inventory the environment for any D-Link DIR-645 routers and verify whether they are still reachable or in service.
  • Disconnect the device if it is still deployed, matching CISA’s KEV guidance for this end-of-life product.
  • Replace the DIR-645 with a supported router or gateway that receives security updates.
  • If short-term operation cannot be avoided, isolate the device on a tightly controlled network segment and limit administrative access until it can be removed.
