CVE-2024-8294Public exploitNetwork attack vector

Authenticated code execution via upload-validation bypass

Published Aug 29, 2024 · Updated Aug 29, 2024

Unrestricted file upload in liufee FeehiCMS 2.1.1 and earlier allows remote authenticated users to execute code via FriendlyLink[image]. Setting the image field to 0 makes the Yii upload validator treat it as empty and skip dangerous-file validation while a multipart PHP file is accepted. An administrative session and valid CSRF token are required; the uploaded file reaches the shared web root, where PHP execution compromises the server.
