CVE-2018-10748: 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 'show' parameter to the '/userfs/bin/tcapi' binary (in the Diagnostics component) using the 'show <node_name>' 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-2018-10748 affects D-Link DSL-3782 EU 1.01 devices. A logged-in user can trigger memory corruption in the Diagnostics component and may be able to run arbitrary code on the router. The sources do not provide CVSS scoring, a vendor patch, or confirmed exploitation.

Executive priority

Treat as a high-priority router exposure if this model and firmware are present. The issue could allow device takeover after authentication, but current public evidence does not confirm active exploitation or a specific vendor fix.

Technical view

The issue is an authenticated buffer handling flaw in /userfs/bin/tcapi when using the Diagnostics show function with a long show parameter. The CVE description states this can corrupt memory and redirect program flow, enabling arbitrary code execution. No CWE, CVSS vector, or remediation detail is provided in the bundle.

Likely exposure

Exposure appears limited to D-Link DSL-3782 EU 1.01 devices, based on the CVE description. Risk is higher where router administration or Diagnostics access is reachable by many users, weak credentials are used, or management interfaces are exposed beyond trusted networks.

Exploitation context

The vulnerability requires authentication according to the CVE description. The source bundle includes a public GitHub reference, but CISA KEV is false and no cited source confirms active exploitation. Evidence is incomplete on real-world exploitation and patch availability.

Researcher notes

The affected metadata in the bundle is sparse, but the CVE description specifically names D-Link DSL-3782 EU 1.01. Analysis should avoid extending impact to other D-Link models or firmware without evidence. Validate exposure through inventory and vendor documentation, not assumptions.

Mitigation direction

  • Inventory D-Link DSL-3782 EU 1.01 devices.
  • Check D-Link or service-provider guidance for firmware fixes or replacement advice.
  • Restrict administrative access to trusted management networks only.
  • Remove unnecessary accounts and enforce strong unique administrator passwords.
  • Monitor for unexpected authenticated Diagnostics activity.

Validation and detection

  • Confirm whether any deployed router is D-Link DSL-3782 EU firmware 1.01.
  • Verify management interfaces are not exposed to untrusted networks.
  • Review account lists for unnecessary or shared authenticated users.
  • Check available vendor or ISP firmware guidance for this exact model and version.
  • Document compensating controls where no patch is confirmed.
