| Título | https://www.campcodes.com/ Online Learning Management System V1.0 Unrestricted Upload |
|---|
| Descripción | The Online Learning Management System (OLMS) suffers from a critical vulnerability categorized as Unrestricted Upload of File with Dangerous Type (CWE-434).
This flaw exists within the lesson attachment upload functionality handled by Crud_model.php. The application fails to enforce a secure whitelist for file extensions. Instead, it renames uploaded files using an MD5 hash but blindly appends the original, user-supplied extension (e.g., .php). Furthermore, the dynamically generated filename and its exact storage path are explicitly disclosed in the HTML source code of the frontend view (lessons.php).
As a result, an attacker can upload a malicious PHP web shell, easily retrieve its hidden path from the frontend, and execute arbitrary system commands, leading to complete Remote Code Execution (RCE) and server compromise. |
