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 SourceCodester E-Learning System 1.0 contains an unrestricted file upload vulnerability in the admin module at /admin/modules/lesson/index.php. The List of Lessons Page component fails to properly validate uploaded file types, sizes, or content, allowing remote attackers to upload malicious files (e.g., PHP webshells) to the server.

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 installed E-Learning System versionLocate and examine version files, about pages, or admin dashboard metadata that displays the software version. Compare against version 1.0.Affected if The software is SourceCodester or Janobe E-Learning System version 1.0.
-
Locate the vulnerable upload endpointCheck if the file /admin/modules/lesson/index.php exists in the web application directory.Affected if The file /admin/modules/lesson/index.php exists and is accessible.
-
Verify upload functionality is enabledAccess the admin panel and navigate to the Lessons module to confirm the file upload feature is present and functional.Affected if The lesson upload functionality is accessible and operational in the admin interface.
-
Check for file type validationInspect the source code of /admin/modules/lesson/index.php to determine if MIME type, file extension, or content validation is implemented on file uploads.Affected if The code lacks proper allowlist-based validation for file type, extension, and content headers.
-
Confirm upload directory is web-accessibleIdentify the upload directory configuration and verify uploaded files are stored within the webroot and accessible via HTTP.Affected if Uploaded files are stored in a publicly accessible web directory without random renaming.
You are affected if running SourceCodester E-Learning System version 1.0 with the lesson upload module at /admin/modules/lesson/index.php accessible and lacking proper file validation controls.
Generated from the published advisory. Verify against your own configuration.
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 validation (checking MIME type, extension, and file content/headers), store uploads outside webroot or rename with random identifiers, and restrict upload functionality to authenticated administrators with proper authorization checks.
