An authentication bypass vulnerability on D-Link DIR-850L Wireless AC1200 Dual Band Gigabit Cloud Router (Hardware Version : A1, B1; Firmware Version : 1.02-2.06) devices potentially allows attackers to bypass SharePort Web Access Portal by directly visiting /category_view.php or /folder_view.php.

Security readout for executives and security teams

Plain-English summary

This issue affects D-Link DIR-850L routers in the listed hardware and firmware ranges. The SharePort Web Access Portal can potentially be bypassed by opening protected view pages directly, so authentication may not be enforced where expected. Business urgency depends on whether those routers and SharePort exposure exist in the environment.

Executive priority

Prioritize remediation for any affected router reachable from the internet or guest networks. If these devices are only isolated internally, handle through normal network hygiene, but validate quickly because the issue is an authentication bypass with public exploit references.

Technical view

CVE-2018-9032 is an authentication bypass in D-Link DIR-850L Wireless AC1200 routers, hardware A1 and B1, firmware 1.02 through 2.06. The CVE states attackers may bypass SharePort Web Access Portal access controls by directly visiting category or folder view PHP pages.

Likely exposure

Exposure is most likely where affected DIR-850L routers are still deployed and the SharePort Web Access Portal is reachable from untrusted networks. The source bundle does not identify CPEs, default exposure, or whether WAN access is required.

Exploitation context

The CVE has a public Exploit-DB reference and a YouTube reference, but it is not listed as CISA KEV in the supplied bundle. Treat exploit availability as public, but do not assume active exploitation without separate evidence.

Researcher notes

The public CVE text is narrow and lacks CVSS, CWE, CPE, patch, and configuration details. Analysis should remain scoped to DIR-850L A1/B1 firmware 1.02-2.06 and SharePort Web Access Portal behavior described in the CVE.

Mitigation direction

  • Inventory D-Link DIR-850L hardware revisions A1 and B1.
  • Identify firmware versions 1.02 through 2.06.
  • Check D-Link guidance for fixed firmware or retirement advice.
  • Restrict SharePort Web Access Portal from untrusted networks.
  • Disable unused SharePort or web access features where operationally possible.

Validation and detection

  • Confirm whether DIR-850L routers exist in network asset records.
  • Verify hardware revision and firmware version from administrative records.
  • Determine whether SharePort Web Access Portal is enabled.
  • Review network controls limiting access to the router web interface.
  • Check monitoring for unexpected access to SharePort view pages.
