| 标题 | SourceCodester Online Examination & Learning Management System 1.0 Unrestricted Upload |

| 描述 | The file /process_lesson.php in Online Examination & Learning Management System 1.0 does not validate file extensions during lesson file upload. Any authenticated user, including a student, can upload a .php webshell to uploads/lessons/ and achieve remote code execution. The authorization check only verifies $_SESSION['user_id'] exists, without inspecting the user's role. No .htaccess exists to block PHP execution in the upload directory. |
