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
An issue was discovered in Sauter NovaWeb web HMI. The application uses a protection mechanism that relies on the existence or values of a cookie, but it does not properly ensure that the cookie is valid for the associated user.

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

Sauter NovaWeb web HMI has a cookie-based authentication bypass vulnerability. The application makes access control decisions based on cookie existence or values without properly validating that the cookie is legitimate and belongs to the requesting user, allowing unauthorized access to protected functionality.

MitigationImplement proper server-side cookie validation using cryptographically signed session tokens, enforce session expiration, and add secondary authentication checks for sensitive operations.

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 Sauter Novaweb Web HMI is present
    Check your installed applications, services, or web servers for 'Sauter Novaweb' or 'Novaweb Web HMI'. Review software inventory or running services on relevant systems.
    Affected if The product is found in your environment
  2. Determine the deployment context
    Identify any systems running the Sauter Novaweb web interface. This may be a dedicated HMI server, a SCADA system, or a web service on port 80/443. Check network scans or service listings.
    Affected if Sauter Novaweb web interface is accessible on your network
  3. Verify cookie-based authentication is in use
    Access the Novaweb login page via browser or HTTP client, then examine HTTP responses for Set-Cookie headers. Capture and inspect cookies sent during authentication attempts.
    Affected if The application sets authentication cookies without proper server-side validation mechanisms
  4. Test for cookie validation weakness
    Send HTTP requests with manipulated or missing cookie values to protected pages/endpoints. Observe if access is granted without proper credentials based on cookie presence alone.
    Affected if Requests with modified, missing, or forged cookies successfully access protected functionality

If Sauter Novaweb Web HMI is deployed in your environment and the application grants access based solely on cookie presence without cryptographic validation, you are affected by this vulnerability.
