CVE-2024-9855Public exploitNetwork attack vector

Authenticated code execution via unfiltered PHP upload

Published Oct 11, 2024 · Updated Oct 11, 2024

Unrestricted file upload in 07FLY-CMS 1.3.8 allows remote authenticated users to execute code by uploading a PHP webshell. The uploadFile path in app/common/logic/Upload.php accepts the file name and contents without server-side filtering, relying only on bypassable browser-side restrictions. Administrator access to the module plug-in handler is required, and a successful upload places executable PHP on the web server.
