| Description | Description: SourceCodester Library Management System (php-lms, commit bb68e5c) allows unauthenticated remote code execution and admin takeover. admin/session.php enforces login with header('location:index.php') but no exit/die, so PHP executes the rest of every admin page for unauthenticated requests. On admin/add_admin.php the handler runs pre-auth: it calls move_uploaded_file(FILES[′image′][′tmpname′],′upload/′._FILES['image']['name']) with only a size check and no extension, MIME, or content validation, placing a PHP web shell at the predictable URL /admin/upload/<name>, and it INSERTs an admin row with hardcoded admin_type='Admin'. One unauthenticated multipart POST yields RCE (live reproduction returned uid=0(root)) plus a working admin login. CVSS 3.1 score 9.8 Critical, vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H.
