Vulnerability Title
File Browser's Signup Grants Execution Permissions When Default Permissions Includes Execution
Vulnerability Description
File Browser is a file managing interface for uploading, deleting, previewing, renaming, and editing files within a specified directory. Prior to version 2.62.2, the signupHandler in File Browser applies default user permissions via d.settings.Defaults.Apply(user), then strips only Admin. The Execute permission and Commands list from the default user template are not stripped. When an administrator has enabled signup, server-side execution, and set Execute=true in the default user template, any unauthenticated user who self-registers inherits shell execution capabilities and can run arbitrary commands on the server. This issue has been patched in version 2.62.2.
