Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
D-Link D-View Use of Hard-coded Cryptographic Key Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of D-Link D-View. Authentication is not required to exploit this vulnerability. The specific flaw exists within the TokenUtils class. The issue results from a hard-coded cryptographic key. An attacker can leverage this vulnerability to bypass authentication on the system. . Was ZDI-CAN-19659.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

This is a critical authentication bypass vulnerability in D-Link D-View's TokenUtils class. The application uses a hard-coded cryptographic key for token generation/validation, allowing remote unauthenticated attackers to forge valid authentication tokens and gain unauthorized access to the system.

MitigationReplace the hard-coded cryptographic key in TokenUtils with a properly managed key (e.g., environment variable, secure key vault) and implement proper key rotation mechanisms. Validate all authentication paths after the fix.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm D-Link D-View 8 installation
    Locate the D-Link D-View application in your environment and verify it is version 8 of the product.
    Affected if The system does not have D-Link D-View 8 installed.
  2. Check installed version number
    Identify the installed version of D-Link D-View 8. This is typically available in the application metadata, about page, or installation directory.
    Affected if The installed version is 2.0.1.27 or lower.
  3. Locate TokenUtils class
    Search the D-View application installation for the TokenUtils class or source code file. This class handles token generation and validation.
    Affected if The TokenUtils class is not found in the application.
  4. Inspect TokenUtils for hard-coded cryptographic key
    Examine the TokenUtils class source code or decompiled bytecode. Look for any hard-coded string literals used as cryptographic keys, particularly in token generation or validation methods.
    Affected if A hard-coded cryptographic key is present in the TokenUtils class (not retrieved from environment variables, secure vault, or configuration management).

You are affected if D-Link D-View 8 is installed with version 2.0.1.27 or lower and the TokenUtils class contains a hard-coded cryptographic key for token operations.

From vendor data
Upgrade available Upgrade to a release after 2.0.1.27
Interim mitigation

Replace the hard-coded cryptographic key in TokenUtils with a properly managed key (e.g., environment variable, secure key vault) and implement proper key rotation mechanisms. Validate all authentication paths after the fix.
