Description
File Browser provides a file managing interface within a specified directory and it can be used to upload, delete, preview, rename and edit files. Prior to version 2.61.0, when a user creates a public share link for a directory, the withHashFile middleware in http/public.go uses filepath.Dir(link.Path) to compute the BasePathFs root. This sets the filesystem root to the parent directory instead of the shared directory itself, allowing anyone with the share link to browse and download files from all sibling directories. This issue has been patched in version 2.61.0.
Analysis
File Browser versions prior to 2.61.0 incorrectly set the filesystem root to a parent directory when generating public share links, enabling any user with a share link to access and download files from sibling directories beyond the intended shared folder. This authenticated network-based vulnerability affects Golang and Filebrowser and has public exploit code available. …
