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

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

Broken Access Control vulnerability in Kashipara Online Exam System v1.0 allows unauthenticated remote attackers to access /admin/update.php and /admin/dashboard.php directly, enabling them to view the administrator dashboard and delete valid user accounts without any authentication or authorization checks.

MitigationImplement proper authentication and session validation for all admin pages, and add role-based access control (RBAC) to ensure only authenticated administrators can access dashboard functions and perform privileged operations like user deletion.

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. Identify the installed product version
    Examine the source code, footer, or any version file in the web application for 'Kashipara Online Exam System' or 'Jayesh Online Exam System' version 1.0. Check README files, config files, or the main index page for version information.
    Affected if The application is running version 1.0 of the Jayesh Online Exam System.
  2. Locate vulnerable admin PHP files
    Check the web server document root for the presence of /admin/update.php and /admin/dashboard.php files. List the contents of the admin directory if accessible via file system or FTP.
    Affected if Both /admin/update.php and /admin/dashboard.php exist in the deployment.
  3. Verify admin page access control
    Send an HTTP GET request to http://yourdomain.com/admin/dashboard.php without providing any session cookies, authentication tokens, or credentials. Similarly test /admin/update.php with no authentication.
    Affected if The admin pages return HTTP 200 and display dashboard content or administrative functionality without requiring login.
  4. Inspect authentication logic in admin files
    Open /admin/dashboard.php and /admin/update.php in a code editor or via file read. Search for session_start(), $_SESSION checks, or include statements that validate user authentication. Check if these files include any authentication wrapper or redirect to login.
    Affected if The admin files contain no session validation, no include of an auth check file, and no redirection to a login page.

The environment is affected if the Jayesh Online Exam System version 1.0 is deployed and the /admin/update.php or /admin/dashboard.php pages are accessible without any authentication.
