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 DeleteAssignments method in IDAttend’s IDWeb application 3.1.052 and earlier allows deletion of 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

This is a broken access control vulnerability where the DeleteAssignments method in IDAttend's IDWeb application 3.1.052 and earlier lacks any authentication verification, allowing any unauthenticated user to send requests that delete assignment data.

MitigationApply the vendor patch or update to a version beyond 3.1.052 that includes authentication on the DeleteAssignments method; if no patch is available, implement network-level access controls to restrict the endpoint to authorized users only.

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
    Check your system for the presence of Idattend Idweb application files or running services. Look for web application directories or services named 'Idweb' or 'IDAttend'.
    Affected if Idattend Idweb is found on the system
  2. Determine the installed version
    Locate the version information for your Idweb installation, typically found in application configuration files, About pages, or the application binary metadata. Compare the version number to the affected range: 3.1.052 and earlier.
    Affected if The installed version is 3.1.052 or earlier
  3. Locate the DeleteAssignments endpoint
    Identify the web endpoint or API path that handles the DeleteAssignments method in your Idweb installation. This is typically found in the application's URL routing configuration or web service definitions.
    Affected if The DeleteAssignments endpoint exists in the application
  4. Test endpoint authentication requirement
    Send an unauthenticated HTTP request directly to the DeleteAssignments endpoint (such as a DELETE or POST request to the appropriate URL path) and observe whether the application accepts and processes the request without requiring login credentials or session tokens.
    Affected if The endpoint accepts and processes requests without any authentication credentials

You are affected if Idattend Idweb version 3.1.052 or earlier is installed and the DeleteAssignments endpoint is accessible without authentication.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.

From vendor data
Upgrade available Upgrade to a release after 3.1.052
Interim mitigation

Apply the vendor patch or update to a version beyond 3.1.052 that includes authentication on the DeleteAssignments method; if no patch is available, implement network-level access controls to restrict the endpoint to authorized users only.
