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
orderdetails.aspx, as made available to Microsoft .NET developers as example code and demonstrated on www.ibuyspystore.com, allows remote attackers to view the orders of other users by modifying the OrderID parameter.

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 an Insecure Direct Object Reference (IDOR) vulnerability in the orderdetails.aspx example file from Microsoft's .NET sample code. The application accepts any OrderID parameter value without verifying that the requesting user is authorized to view that specific order, allowing attackers to access arbitrary customer order data by simply modifying the OrderID parameter.

MitigationImplement proper session-based authorization checks to verify the authenticated user owns or has permission to view the requested order before returning any order details.

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. Locate the vulnerable sample file
    Search web application directories for files named 'orderdetails.aspx' that are part of .NET sample applications
    Affected if The file exists in a deployed web application directory and is accessible via HTTP
  2. Verify .NET Framework version
    Check the installed .NET Framework version on the web server (check registry key or use aspnet_regiis -i with version info)
    Affected if The server is running .NET Framework 1.0
  3. Test for IDOR vulnerability
    Access the orderdetails.aspx page with a valid OrderID, then modify the OrderID parameter to a different value without being logged in or authorized for that order
    Affected if The application returns order details for arbitrary OrderID values without verifying user ownership
  4. Check authorization implementation
    Inspect the code-behind or logic in orderdetails.aspx (or its associated handler) to determine if session-based authorization checks exist before returning order data
    Affected if No code verifies that the authenticated user owns or has permission to view the requested OrderID

You are affected if orderdetails.aspx from .NET 1.0 sample code is deployed and accessible without proper authorization checks on the OrderID parameter.

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.
