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 InstallApplication Use of Hard-coded Credentials 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 InstallApplication class. The class contains a hard-coded password for the remotely reachable database. An attacker can leverage this vulnerability to bypass authentication on the system. Was ZDI-CAN-19553.

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

D-Link D-View contains hard-coded credentials embedded in the InstallApplication class that provide remote access to the database. Since these credentials are static and discoverable (likely through reverse engineering or configuration file analysis), unauthenticated remote attackers can use them to bypass the application's authentication mechanism and gain unauthorized access to the system.

MitigationRemove all hard-coded credentials from the InstallApplication class and implement proper credential management using secure storage mechanisms such as environment variables, a secrets vault, or encrypted configuration files. Validate that authentication cannot be bypassed using the former hard-coded credentials.

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. Identify if D-Link D-View 8 is installed
    Check for D-View installation directories (common locations: C:\Program Files\D-Link\D-View or C:\Program Files (x86)\D-Link\D-View), or look for the D-View service in Windows Services.
    Affected if D-Link D-View 8 software is present on the system
  2. Verify the installed version
    Check the application version by right-clicking the executable, viewing the properties of the D-View installation folder, or querying the Windows Registry under HKLM\SOFTWARE\D-Link\D-View for the Version value.
    Affected if The version reported is 1.0.2.13 exactly (the only affected version)
  3. Locate the InstallApplication class file
    Search for InstallApplication.class or InstallApplication.java within the D-View installation directory, particularly in the WEB-INF/classes or application JAR/WAR files.
    Affected if The InstallApplication class file exists in the D-View application directory
  4. Inspect for hard-coded credentials
    Open the InstallApplication class file using a decompiler or hex editor and search for hard-coded strings such as database usernames and passwords, looking for static credential strings in the class code.
    Affected if Hard-coded credentials (usernames/passwords) are found embedded in plain text within the InstallApplication class
  5. Check application network exposure
    Verify if the D-View web interface (typically on ports 8080 or 8443) is exposed to the network or internet by reviewing firewall rules and listening network ports.
    Affected if D-View is accessible from untrusted networks without proper network segmentation

A user is affected if D-Link D-View version 1.0.2.13 is installed and the InstallApplication class containing hard-coded database credentials is present and accessible on the system.

Mitigation

Remove all hard-coded credentials from the InstallApplication class and implement proper credential management using secure storage mechanisms such as environment variables, a secrets vault, or encrypted configuration files. Validate that authentication cannot be bypassed using the former hard-coded credentials.
