CVE-2018-10746: An issue was discovered on D-Link DSL-3782 EU 1.01 devices.

An issue was discovered on D-Link DSL-3782 EU 1.01 devices. An authenticated user can pass a long buffer as a 'get' parameter to the '/userfs/bin/tcapi' binary (in the Diagnostics component) using the 'get <node_name attr>' function and cause memory corruption. Furthermore, it is possible to redirect the flow of the program and execute arbitrary code.

Security readout for executives and security teams

Plain-English summary

CVE-2018-10746 affects D-Link DSL-3782 EU firmware 1.01. An authenticated user can trigger memory corruption in a diagnostics-related binary and may execute arbitrary code. This is serious for organizations still running the device, but the source bundle does not provide CVSS, a vendor fix, or evidence of active exploitation.

Executive priority

Treat this as a high-priority legacy network-device risk if the affected model is present. Business urgency depends on deployment count, management-interface exposure, and whether a supported firmware or replacement path exists.

Technical view

The issue is in /userfs/bin/tcapi, reached through the Diagnostics component. A long buffer supplied as a get parameter to the get <node_name attr> function can corrupt memory and redirect program flow. The CVE record identifies D-Link DSL-3782 EU 1.01 devices; no CWE, CVSS vector, or confirmed patch is provided.

Likely exposure

Exposure is most likely where D-Link DSL-3782 EU devices running firmware 1.01 are still deployed and the administrative or diagnostics interface is reachable to authenticated users. The bundle does not identify other affected firmware versions or products.

Exploitation context

The CVE description states arbitrary code execution is possible after authentication. The source bundle does not show CISA KEV listing, public active exploitation evidence, exploit maturity details, or unauthenticated reachability.

Researcher notes

Evidence is sparse: the CVE record names the vulnerable binary, diagnostics path, input pattern, and code-execution impact, but provides no CVSS, CWE, patch statement, or confirmed exploitation. Do not broaden affected versions beyond D-Link DSL-3782 EU 1.01 without additional vendor evidence.

Mitigation direction

  • Inventory D-Link DSL-3782 EU devices and confirm firmware versions.
  • Restrict administrative and diagnostics access to trusted management networks.
  • Review administrator accounts and remove unnecessary authenticated users.
  • Check D-Link or service-provider guidance for firmware updates or replacement options.
  • Retire affected devices if no supported fix is available.

Validation and detection

  • Confirm whether any D-Link DSL-3782 EU firmware 1.01 devices are in use.
  • Verify management interfaces are not reachable from untrusted networks.
  • Review device logs for unusual authenticated diagnostics activity.
  • Check vendor or provider advisories for firmware status and replacement guidance.
