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
code-projects Computer Book Store 1.0 is vulnerable to File Upload in admin_add.php.

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 Computer Book Store 1.0 application contains an unauthenticated file upload vulnerability in admin_add.php, allowing attackers to upload arbitrary files to the server. This critical flaw likely enables remote code execution by uploading malicious PHP scripts that can be subsequently accessed and executed.

MitigationImplement strict server-side file validation including allowlist-based extension checking, MIME type verification, content inspection, and store uploaded files outside the web root or with non-executable extensions.

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. Confirm Carmelo Computer Book Store installation
    Search for files or directories containing 'computer book store' or 'carmelo' in your web server document root. Look for application files such as admin_add.php, index.php, or configuration files that identify the application.
    Affected if The application named 'Carmelo Computer Book Store' version 1.0 is found installed on the server
  2. Verify the vulnerable file exists
    Check if the file admin_add.php exists in the application directory. This file is located in the admin/ folder or similar administrative path within the application structure.
    Affected if The file admin_add.php exists in the application installation directory
  3. Check if the upload endpoint is accessible without authentication
    Attempt to access the admin_add.php file via HTTP/HTTPS from an unauthenticated request, or examine server access logs for requests to this endpoint without prior authentication cookies or headers.
    Affected if The admin_add.php file can be accessed without requiring login credentials or session authentication
  4. Determine if file uploads are processed and stored in web root
    Inspect the application configuration or perform a test upload (with safe files only) to identify where uploaded files are stored. Check if the upload directory is within the web server's document root and serves executable file types.
    Affected if Uploaded files are stored in a web-accessible directory and can be accessed via browser to execute (e.g., .php files in web root)

Your environment is affected if you have Carmelo Computer Book Store 1.0 installed with the admin_add.php file accessible without authentication and file uploads are stored in a web-accessible location where they can be executed.
