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
Cross-Site request forgery (CSRF) vulnerability in Sync Breeze Enterprise Server v10.4.18 and Disk Pulse Enterprise v10.4.18. An authenticated user could cause another user to perform unwanted actions within the application they are logged into. This vulnerability is possible due to the lack of proper CSRF token implementation. Among other things, it is possible, using a POST request to change a user's password or create users via '/setup_login?sid=', affecting the 'username', 'password', and 'cpassword' parameters.

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

CSRF vulnerability in Sync Breeze Enterprise Server and Disk Pulse Enterprise v10.4.18 allows authenticated attackers to trick users into performing unwanted actions via malicious POST requests to '/setup_login?sid='. The lack of anti-CSRF tokens on endpoints handling 'username', 'password', and 'cpassword' parameters enables password changes or user creation.

MitigationImplement synchronizer token pattern (anti-CSRF tokens) on all state-changing endpoints including '/setup_login', and validate Origin/Referer headers as additional defense.

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 installed Flexense product and version
    Check installed software or running service for Disk Pulse Enterprise or Sync Breeze Enterprise, and determine the exact version number
    Affected if Version is exactly 10.4.18 for either product
  2. Confirm web interface accessibility
    Access the application's web interface on the default HTTP port (typically 80 or 8080) or the port where the service is running
    Affected if Web interface is accessible and responds to HTTP requests
  3. Locate the vulnerable endpoint
    Navigate to the '/setup_login' endpoint in the web interface (e.g., http://target:port/setup_login)
    Affected if The endpoint returns a login or user management form
  4. Check for anti-CSRF token presence
    Examine the HTML source of the form at '/setup_login' for the presence of hidden input fields containing anti-CSRF tokens (e.g., 'csrf_token', 'token', or similar) when submitting username, password, or cpassword parameters
    Affected if The form lacks anti-CSRF token fields in the HTML and does not validate tokens on POST requests
  5. Verify state-changing parameter handling
    Submit a POST request to '/setup_login?sid=' with username/password/cpassword parameters and observe whether the application accepts the request without requiring a token
    Affected if The application processes the request without rejecting it due to missing CSRF protection

User is affected if running Disk Pulse Enterprise or Sync Breeze Enterprise version 10.4.18 with the web interface accessible and the /setup_login endpoint lacks anti-CSRF token validation on forms handling username, password, or cpassword parameters.
