CVE-2017-14418: The D-Link NPAPI extension, as used in conjunction with D-Link DIR-850L REV.

The D-Link NPAPI extension, as used in conjunction with D-Link DIR-850L REV. B (with firmware through FW208WWb02) devices, sends the cleartext admin password over the Internet as part of interaction with mydlink Cloud Services.

Security readout for executives and security teams

Plain-English summary

This issue can expose a D-Link router administrator password in clear text when the D-Link NPAPI extension interacts with mydlink Cloud Services. If an organization still uses affected DIR-850L Rev. B devices, the router admin credential should be treated as potentially exposed.

Executive priority

Prioritize remediation if affected routers are still deployed, especially in business networks. The issue concerns administrator credential exposure, not a minor device crash. Because the source bundle lacks a named patch, require asset confirmation and vendor-guidance review before closure.

Technical view

CVE-2017-14418 covers the D-Link NPAPI extension used with DIR-850L Rev. B firmware through FW208WWb02. The reported flaw is cleartext transmission of the admin password over the Internet during mydlink Cloud Services interaction. The source bundle does not provide CVSS, CWE, patch, or mitigation details.

Likely exposure

Exposure is likely limited to environments with D-Link DIR-850L Rev. B devices using firmware through FW208WWb02 and interacting with mydlink Cloud Services through the NPAPI extension.

Exploitation context

The provided sources do not show CISA KEV listing or confirmed active exploitation. The risk is credential disclosure in transit, which could enable unauthorized router administration if the password is intercepted or otherwise obtained.

Researcher notes

The evidence is narrow: one CVE description and the referenced 2017 disclosure. Affected scope is DIR-850L Rev. B through FW208WWb02 with the D-Link NPAPI and mydlink Cloud Services path. Do not generalize this CVE to other D-Link models without separate evidence.

Mitigation direction

  • Check D-Link guidance for DIR-850L Rev. B and the mydlink Cloud/NPAPI component.
  • Disable or avoid mydlink Cloud Services/NPAPI use until vendor guidance confirms safe operation.
  • Restrict router administration to trusted local networks only.
  • Rotate router administrator passwords after removing or mitigating the cleartext transmission path.
  • Consider replacing affected legacy devices if no supported fix is available.

Validation and detection

  • Inventory D-Link DIR-850L Rev. B devices and record firmware versions.
  • Confirm whether any device is running firmware through FW208WWb02.
  • Determine whether mydlink Cloud Services or the NPAPI extension is in use.
  • Review network controls around router administration and cloud-service access.
  • Check vendor advisories before concluding a device is remediated.
