CVE-2026-9379: Edimax BR-6675nD POST Request formWpsStart command injection

A weakness has been identified in Edimax BR-6675nD 1.12. This impacts the function formWpsStart of the file /goform/formWpsStart of the component POST Request Handler. This manipulation of the argument pinCode causes command injection. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks. The vendor was contacted early about this disclosure but did not respond in any way.

Analyst readout for executives and security teams

Plain-English summary

CVE-2026-9379 affects Edimax BR-6675nD firmware 1.12. A remote authenticated attacker could abuse a WPS-related POST handler to run injected commands. Public proof-of-concept material is reported, but the bundle does not show active exploitation or a vendor fix.

Executive priority

Treat this as a moderate, targeted network-edge risk. Prioritize exposed or unmanaged routers first, because public exploit material lowers the barrier once an attacker has credentials or access.

Technical view

The flaw is command injection in /goform/formWpsStart, specifically the formWpsStart POST request handler processing the pinCode argument. CVSS v2 is 6.5 with network access, low complexity, and authentication required. VulDB maps it to CWE-74 and CWE-77 and notes public exploit availability.

Likely exposure

Exposure is limited to Edimax BR-6675nD devices running version 1.12, especially where administrative or WPS-related router interfaces are reachable by untrusted users.

Exploitation context

The source bundle says a public exploit exists, but KEV is false and no cited source states active exploitation. Authentication is required according to the CVSS vector and CTI permission signal.

Researcher notes

Evidence supports command injection in a specific POST handler and argument, with public PoC availability. The bundle does not include vendor confirmation, active exploitation evidence, or an official fix. Avoid assuming broader Edimax impact beyond BR-6675nD 1.12.

Mitigation direction

  • Check Edimax for updated firmware or advisory; no patch is named in the provided sources.
  • Restrict router administration interfaces to trusted networks or VPN-only access.
  • Remove public WAN access to management endpoints wherever present.
  • Replace or retire affected devices if no vendor-supported fix exists.
  • Review router accounts and remove unnecessary administrative access.

Validation and detection

  • Inventory Edimax BR-6675nD devices and confirm firmware version 1.12.
  • Verify management and WPS-related endpoints are not exposed to the internet.
  • Review device logs for unexpected POST activity to /goform/formWpsStart.
  • Confirm only trusted administrators can authenticate to affected routers.
  • Track CVE and VulDB records for vendor response or remediation updates.
