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
An arbitrary file upload vulnerability in the component \modstudent\controller.php of Pisay Online E-Learning System using PHP/MySQL v1.0 allows attackers to execute arbitrary code via uploading a crafted file.

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 Pisay Online E-Learning System v1.0 contains an arbitrary file upload vulnerability in the modstudent/controller.php component. Attackers can upload malicious files (such as PHP scripts) through this endpoint and achieve remote code execution on the server.

MitigationImplement strict file type allowlisting, validate file MIME types and extensions server-side, store uploads outside the web root, rename uploaded files, and disable script execution in upload directories.

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 Pisay Online E-Learning System installation
    Look for the application web directory or check running web services for 'Pisay' or 'Online E-Learning System' branding. Check common web root directories for the application.
    Affected if The Pisay Online E-Learning System v1.0 is installed on the server
  2. Verify the application version
    Check for version information in the application source code, README files, or administration panel. Compare against v1.0.
    Affected if The installed version is v1.0
  3. Confirm modstudent/controller.php exists
    Locate the modstudent directory within the application web root and verify controller.php is present. This is the vulnerable upload endpoint.
    Affected if The file modstudent/controller.php exists in the application directory
  4. Check if upload functionality is accessible
    Verify the modstudent module is enabled and accessible. Test if the upload endpoint at modstudent/controller.php is reachable via HTTP POST requests.
    Affected if The modstudent module and its upload functionality are enabled and exposed to users

The system is affected if Pisay Online E-Learning System v1.0 is installed with the modstudent/controller.php file present and the upload feature accessible.
