CVE-2025-8255
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 · uneditedA vulnerability was found in code-projects Exam Form Submission 1.0. It has been rated as critical. This issue affects some unknown processing of the file /register.php. The manipulation of the argument image leads to unrestricted upload. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.
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 confidenceAn unrestricted file upload vulnerability exists in code-projects Exam Form Submission 1.0 within the /register.php endpoint. The 'image' argument accepts arbitrary file uploads without proper validation, allowing remote attackers to upload malicious files such as web shells by manipulating the upload mechanism.

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.
-
Confirm Exam Form Submission 1.0 is installedLocate the application installation directory and verify the presence of register.php. Check version.php or any version file if available, or review application documentation for version confirmation.Affected if The installed version is exactly 1.0 of Code Projects Exam Form Submission.
-
Verify the /register.php endpoint existsCheck the web server document root for the register.php file. If the application is web-accessible, attempt to access the endpoint directly.Affected if The /register.php file exists in the application directory.
-
Identify if the image parameter accepts file uploadsExamine the register.php source code and look for an HTML form element with name='image' and type='file', or inspect the PHP handling code for $_FILES['image'] or similar file upload handling.Affected if The register.php file contains a file upload field named 'image' and processes it via PHP file upload arrays.
-
Check for file type validation on uploadsReview register.php code for validation logic such as checking $_FILES['image']['type'], file extension allowlists, magic byte verification, or mime_content_type/finfo_file calls before processing the upload.Affected if No file type, extension, or content validation exists in the upload handling code, or validation can be easily bypassed.
-
Determine if uploads are stored in web-accessible locationLocate the directory where uploaded files are moved via move_uploaded_file() or similar functions. Check if this directory is within the web server's document root and accessible via HTTP.Affected if Uploaded files are stored in a web-accessible directory without restrictions.
You are affected if Code Projects Exam Form Submission version 1.0 is installed and the /register.php endpoint accepts file uploads through the 'image' parameter without proper file type validation and stores uploads in a web-accessible location.

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 file upload validation including allowlist of permitted file types, verify file content/magic bytes, store uploads outside the webroot or in non-executable directories, randomize filenames, and disable script execution in upload directories.
