| Titel | Feehi feehi cms 2.1.1 Unauthorized |
|---|
| Beschreibung | FeehiCMS 2.1.1 is configured with 'assets/*' in the backend AccessControl allowActions whitelist (backend/config/main.php), making the UEditor file upload widget accessible without authentication. The UEditor widget exposes uploadImage, uploadFile (30+ extensions), catchImage, listImage/listFile and config actions to unauthenticated attackers. CSRF protection is also explicitly disabled in UeditorAction::init().
Root cause:
- backend/config/main.php: 'assets/*' in allowActions whitelist
- backend/widgets/ueditor/UeditorAction.php: enableCsrfValidation = false
- backend/widgets/ueditor/config.json: permissive fileAllowFiles list
- No MIME type validation, only extension check
Impact:
Unauthenticated attackers can upload arbitrary files (including .txt, .md, .xml, .zip), enumerate uploaded files, and host phishing/malware content.
Proof of Concept:
curl -X POST "http://TARGET:18080/admin/index.php?r=assets/ueditor&action=uploadfile" -F "[email protected]"
Remediation:
Remove 'assets/*' from allowActions, add authentication check, re-enable CSRF validation, restrict file types, add MIME validation.
