| Title | light0011 cms f72cf46f601efb2a0618c3814cc2f61380b38930 File and Directory Information Exposure |
|---|
| Description | `Public/Home/js/uploadify/check-exists.php:9-15` and `Public/Admin/js/uploadify/check-exists.php:9-15` append an untrusted `POST filename` to `$_SERVER['DOCUMENT_ROOT'] . '/uploads/'` and disclose the result of `file_exists()` as `1` or `0`. No canonicalization or traversal rejection occurs. Where the expected `uploads` directory exists, an unauthenticated request such as `filename=../../../../etc/passwd` escapes the intended directory and reveals the existence of arbitrary server paths, aiding filesystem reconnaissance.
