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 checksWork through these to decide whether this CVE applies to you.
-
Identify if running SourceCodester Shopping Cart SystemCheck web application fingerprinting - look for pages or scripts referencing 'Simple and Beautiful Shopping Cart System' in source code, headers, or footer. Check index.php, config files, or meta tags for application name.Affected if The application is SourceCodester Simple and Beautiful Shopping Cart System version 1.0
-
Check installed versionLocate version information in source files (version.php, README, or config files) or admin panel. Compare against version 1.0.Affected if Version is exactly 1.0
-
Locate upload.php fileSearch web root for upload.php file - common paths include /upload.php, /includes/upload.php, or /admin/upload.php. Use directory enumeration or check if file exists.Affected if upload.php file exists in the web application directory
-
Verify upload functionality is accessibleAttempt to access upload.php directly via HTTP request (GET or POST). Check for HTTP 200 response indicating the script is reachable.Affected if upload.php is accessible via web request (returns 200 OK)
-
Inspect file upload validation logicExamine upload.php source code for lack of file type/extension validation, no MIME type checks, no magic byte validation, and no authentication checks before file processing.Affected if upload.php contains no file type/extension validation, no MIME type checks, no authentication requirement, and directly moves uploaded files to accessible web directory
You are affected if your environment runs SourceCodester Simple and Beautiful Shopping Cart System version 1.0 with the upload.php file accessible and lacking proper file validation checks.

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 dataImplement strict allowlist-based file type validation (both MIME type and extension), validate file content/magic bytes, rename uploaded files with random identifiers, store uploads outside the web root, and disable script execution in the upload directory.
