CVE-2026-1423
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 determined in code-projects Online Examination System 1.0. Affected by this issue is some unknown functionality of the file /admin_pic.php. Executing a manipulation can lead to unrestricted upload. The attack may be performed from remote. The exploit has been publicly disclosed and may be utilized.
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 confidenceThe Online Examination System 1.0 contains an unrestricted file upload vulnerability in /admin_pic.php, allowing remote attackers to upload arbitrary files to the server without proper validation. This can lead to remote code execution if malicious files (e.g., PHP webshells) are uploaded and accessed.

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 installation of Fabian Online Examination SystemLocate the application files and identify if the system is the Fabian Online Examination System version 1.0 by checking application directories, headers, or any identification filesAffected if The application is Fabian Online Examination System version 1.0
-
Verify admin_pic.php existsCheck for the presence of the file admin_pic.php in the web server directories, typically under an /admin/ pathAffected if The file admin_pic.php exists in the application directory
-
Test upload functionality accessibilityAttempt to access the admin_pic.php endpoint directly via HTTP request to determine if the upload form is reachableAffected if The admin_pic.php endpoint is accessible without proper authentication or authorization
-
Check for file validation in admin_pic.phpInspect the source code of admin_pic.php to determine if file type validation (extension, MIME type, or magic bytes) is implemented before allowing uploadsAffected if No file type validation is present in the code, or validation can be easily bypassed
-
Determine uploaded file storage locationIdentify where uploaded files are stored - check if they are saved within the web root and can be accessed via HTTPAffected if Uploaded files are stored in a web-accessible directory and can be executed when accessed
You are affected if Fabian Online Examination System 1.0 is installed and the admin_pic.php file upload endpoint lacks proper file type validation and stores files 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 type validation (both by extension and MIME content-type), verify file contents using magic bytes, enforce proper authentication and authorization checks, and store uploaded files outside the web root or in a non-executable directory with restricted access.
