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
A vulnerability was identified in z-9527 admin 1.0/2.0. The affected element is the function checkName/register/login/getUser/getUsers of the file /server/controller/user.js. The manipulation leads to sql injection. The attack can be initiated remotely. The exploit is publicly available and might be used. The vendor was contacted early about this disclosure but did not respond in any way.

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

A SQL injection vulnerability exists in the z-9527 admin application (versions 1.0 and 2.0) within /server/controller/user.js. Multiple user-facing functions (checkName, register, login, getUser, getUsers) fail to properly sanitize user input before using it in SQL queries, allowing remote attackers to inject malicious SQL code.

MitigationReplace dynamic SQL query construction with parameterized queries or prepared statements across all affected functions in user.js. Implement proper input validation and output encoding as defense-in-depth.

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 z-9527 admin application version
    Inspect the application's package.json, version manifest, or the main entry file for a version identifier matching 1.0 or 2.0
    Affected if The installed version is 1.0 or 2.0 of the z-9527 admin application
  2. Locate the vulnerable user.js controller
    Search for the file at /server/controller/user.js within the application codebase
    Affected if The file /server/controller/user.js exists in the application installation
  3. Inspect affected functions for unsanitized SQL input
    Open user.js and review the checkName, register, login, getUser, and getUsers functions for direct string concatenation or template literals used in SQL query construction without parameterized queries
    Affected if Any of these five functions use dynamic SQL query construction (e.g., 'SELECT * FROM users WHERE name = ' + username) instead of prepared statements or parameterized queries
  4. Verify the application accepts user input
    Confirm that the affected endpoints are exposed and accessible, typically via HTTP routes that map to these functions (e.g., /api/user/checkName, /api/user/register, /api/user/login)
    Affected if The application exposes HTTP endpoints that invoke the vulnerable functions with unsanitized user-supplied input
  5. Check for web-facing exposure
    Determine if the application server is accessible from network locations where attackers could send malicious SQL payloads through HTTP requests
    Affected if The z-9527 admin application is accessible over the network without additional authentication barriers beyond the vulnerable login function

You are affected if you are running z-9527 admin application version 1.0 or 2.0 with the /server/controller/user.js file present and any of the checkName, register, login, getUser, or getUsers functions using unsanitized SQL query construction.
