| 説明 | The front-end widget editor in `dmFrontPlugin/modules/dmWidget` is accessible to users with the `widget_edit` or `widget_edit_fast` credential. Its media form, `dmFrontPlugin/lib/dmWidget/media/dmWidgetContentBaseMediaForm.php`, validates uploaded files with `sfValidatorFile` without an extension or MIME allowlist and creates a `DmMedia` item in the `widget` folder. `dmCorePlugin/lib/model/doctrine/PluginDmMedia.class.php` retains the submitted extension, saves the file below `sf_upload_dir`, and exposes it through `sf_upload_dir_name`. A content editor can upload `payload.php`, which is served as `/uploads/widget/payload.php`; deployments whose PHP handler executes PHP files in the web-root upload directory are vulnerable to remote code execution as the web-server account. |
