CVE-2026-23754: D-Link D-View 8 IDOR Allows Credential Disclosure and Account Takeover

D-Link D-View 8 versions 2.0.1.107 and below contain an improper access control vulnerability in backend API endpoints. Any authenticated user can supply an arbitrary user_id value to retrieve sensitive credential data belonging to other users, including super administrators. The exposed credential material can be reused directly as a valid authentication secret, allowing full impersonation of the targeted account. This results in complete account takeover and full administrative control over the D-View system.

Security readout for executives and security teams

Plain-English summary

D-Link D-View 8 has an access control flaw where a logged-in user can access credential material for other accounts, including super administrators. Those secrets can be reused to impersonate the target account, potentially giving an attacker full administrative control of the D-View system.

Executive priority

Treat this as a high-priority remediation item for any D-View deployment. A single compromised ordinary account could become full administrative control of the monitoring platform.

Technical view

The issue is an IDOR/CWE-639 in backend API endpoints. An authenticated low-privileged user can provide another user_id and retrieve sensitive credential data. CVSS 4.0 is 8.7, with network attack vector, low complexity, low privileges required, no user interaction, and high vulnerable-system impact.

Likely exposure

Exposure is most relevant to organizations running D-Link D-View 8 version 2.0.1.107 or below, especially where multiple users have authenticated access to the management application or its backend APIs.

Exploitation context

The bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires valid authentication, but not administrator rights, making insider misuse or compromised low-privileged accounts the main concern.

Researcher notes

The affected range is stated as D-View 8 version 2.0.1.107 and below. The bundle’s affected metadata is sparse, so validate exact product/version applicability against D-Link SAP10471 and VulnCheck before closing exposure.

Mitigation direction

  • Review D-Link SAP10471 and apply the vendor-provided patch or upgrade guidance.
  • Restrict D-View access to trusted administrators and management networks.
  • Audit D-View user accounts and remove unnecessary low-privileged access.
  • Rotate D-View credentials where exposure or suspicious access is suspected.
  • Monitor vendor guidance for clarified fixed versions or compensating controls.

Validation and detection

  • Inventory D-Link D-View deployments and confirm running versions.
  • Check whether any deployment is version 2.0.1.107 or below.
  • Review logs for low-privileged users accessing credential-related user records.
  • Confirm backend APIs enforce object-level authorization for user_id-based requests.
  • Investigate unusual super administrator activity following low-privileged account activity.
