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
Sielco PolyEco1000 is vulnerable to an improper access control vulnerability when the application provides direct access to objects based on user-supplied input. As a result of this vulnerability attackers can bypass authorization and access resources behind protected pages.

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 Sielco PolyEco1000 suffers from an improper access control vulnerability (Insecure Direct Object Reference / IDOR) where the application uses user-supplied input to directly access objects without proper authorization validation. This allows unauthenticated or unauthorized attackers to bypass authentication mechanisms and access sensitive resources residing behind protected pages.

MitigationImplement proper authorization checks on all object references to verify the authenticated user has permission to access the requested resource, and avoid using direct object references in URLs or parameters without validation.

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 device model and firmware version
    Access the device web interface and check the firmware version in the system information or about page. Alternatively, check HTTP headers or the login page source for version strings.
    Affected if The firmware version matches one of the affected versions: Polyeco500 (=1.7.0, =10.16), Polyeco300 (=2.0.0, =2.0.2, =10.19), Polyeco1000 (=1.9.3, =1.9.4, =2.0.6, =10.19)
  2. Verify web interface is accessible
    Confirm the device web management interface is reachable on the network by accessing the device IP address over HTTP/HTTPS.
    Affected if The web interface is exposed and reachable (required for this web-based vulnerability to be exploitable)
  3. Test for unauthenticated access to protected resources
    Attempt to access protected pages or endpoints directly (without logging in) by manipulating URL parameters or object references. Compare your installed version to the affected ranges.
    Affected if Protected resources can be accessed without authentication or authorization validation, indicating the IDOR vulnerability is present

You are affected if your Polyeco device firmware matches any of the listed versions AND the web interface allows unauthorized access to protected resources without proper authorization checks.

Mitigation

Implement proper authorization checks on all object references to verify the authenticated user has permission to access the requested resource, and avoid using direct object references in URLs or parameters without validation.
