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
Missing authentication in the StudentPopupDetails_StudentDetails method in IDAttend’s IDWeb application 3.1.052 and earlier allows extraction of sensitive student data by unauthenticated attackers.

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

Missing authentication in the StudentPopupDetails_StudentDetails method of IDAttend's IDWeb application allows unauthenticated attackers to bypass access controls and extract sensitive student PII by directly invoking the vulnerable endpoint without any credentials.

MitigationApply vendor patch (upgrade to version 3.1.053 or later) or implement proper authentication/authorization checks on the StudentPopupDetails_StudentDetails method to ensure only authorized users can access student data.

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 Idattend Idweb is installed
    Locate the Idattend Idweb application in your environment. This is typically a web application accessible via browser. Confirm the product name and vendor match 'Idattend Idweb'.
    Affected if The Idattend Idweb application is present in your environment.
  2. Determine the installed version
    Check the application version displayed in the Idweb interface, or query the application metadata, configuration files, or About/Version information within the Idweb application. Compare your version number against the affected range.
    Affected if The installed version is 3.1.052 or any lower version number.
  3. Verify the vulnerable endpoint exists
    Attempt to access the StudentPopupDetails_StudentDetails endpoint directly via the Idweb application URL. This is typically found in the web application's URL structure. Check if the endpoint responds to HTTP requests.
    Affected if The StudentPopupDetails_StudentDetails endpoint is accessible and responds to requests.
  4. Confirm lack of authentication enforcement
    Send a request to the StudentPopupDetails_StudentDetails endpoint WITHOUT providing any credentials, session tokens, or login cookies. Observe whether the application returns student PII data or allows access without authentication.
    Affected if The endpoint returns student PII data or grants access without requiring any authentication credentials.

You are affected if Idattend Idweb version 3.1.052 or lower is installed AND the StudentPopupDetails_StudentDetails endpoint is accessible without authentication credentials.
