Who should care

Organizations that operate or manage D-Link DSL-2750B devices, especially network and security teams responsible for edge devices, remote management, and lifecycle planning. Asset owners should care most if these devices are internet-facing or otherwise difficult to isolate.

Technical summary

The official source corpus identifies this issue as a command injection vulnerability in D-Link DSL-2750B devices. CISA classifies it as a known exploited vulnerability and links to the vendor advisory for mitigation guidance. The supplied record does not include affected versions, attack preconditions, or a CVSS score, so defenders should rely on the official vendor notice and inventory to determine exposure.

Defensive priority

High. CISA KEV inclusion means this vulnerability has been observed exploited in the wild, so exposed systems should be remediated or removed from service promptly.

Recommended defensive actions

  • Inventory all D-Link DSL-2750B devices and determine whether any are exposed or actively used.
  • Review the linked vendor advisory and apply mitigations exactly as instructed by the vendor.
  • If mitigations are unavailable or cannot be validated, discontinue use of the product and replace it.
  • Prioritize isolation or removal of any internet-facing instances until remediation is complete.
  • Confirm remediation by rechecking device inventory and configuration after changes.

Evidence notes

CISA’s KEV entry names the issue as a D-Link DSL-2750B Devices Command Injection Vulnerability and marks it as known exploited. The KEV metadata instructs defenders to apply vendor mitigations or discontinue use if mitigations are unavailable.
