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
The Le-yan dental management system contains a hard-coded credentials vulnerability in the web page source code, which allows an unauthenticated remote attacker to acquire administrator’s privilege and control the system or disrupt service.

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 · moderate confidence

The Le-yan dental management system contains hard-coded credentials embedded in web page source code. An unauthenticated remote attacker can discover these credentials in the source and use them to authenticate as an administrator, gaining full control of the system or causing service disruption.

MitigationRemove all hard-coded credentials from source code, implement secure credential management (e.g., environment variables, secrets management), rotate any exposed credentials, and audit the codebase for additional hard-coded secrets.

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 the installed Le Yan Dental Management System version
    Access the system admin panel, typically at /admin or /login, and locate the version information in the About, Settings, or Help section. Alternatively, check version files in the web root directory or configuration files (e.g., version.php, config.json, or similar).
    Affected if The installed version is exactly 2.8.5
  2. Inspect web page source code for hard-coded credentials
    Navigate to the login page of the Le Yan Dental Management System. Right-click and select 'View Page Source' or press F12 to open developer tools. Search the source code for keywords such as 'password', 'pwd', 'credential', 'username', 'admin', or hard-coded strings that resemble passwords (e.g., alphanumeric strings in plain text or encoded forms).
    Affected if Hard-coded credentials, usernames, or passwords are found embedded in the HTML, JavaScript, or client-side code of any web page
  3. Check JavaScript files for embedded secrets
    In the browser developer tools, examine all loaded JavaScript files (look in the Sources or Network tab). Search for hard-coded strings that could be credentials, API keys, or authentication tokens. Pay particular attention to authentication-related JavaScript files.
    Affected if Credentials or secrets are found hard-coded in any JavaScript file served by the application
  4. Review authentication-related source code
    If you have access to the application source code, search all source files for hard-coded password strings, default credentials, or embedded login credentials. Look for patterns like 'password =', 'pwd:', 'adminPassword', or similar hard-coded credential assignments.
    Affected if Hard-coded credentials are present in the source code repository

You are affected if the installed version is 2.8.5 AND hard-coded credentials are discoverable in the web page source code or JavaScript files.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

Mitigation

Remove all hard-coded credentials from source code, implement secure credential management (e.g., environment variables, secrets management), rotate any exposed credentials, and audit the codebase for additional hard-coded secrets.
