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 2.33.10, the implementation of the allowlist is erroneous, allowing a user to execute more shell commands than they are authorized for. The concrete impact of this vulnerability depends on the commands configured, and the binaries installed on the server or in the container image. Due to the missing separation of scopes on the OS-level, this could give an attacker access to all files managed the application, including the File Browser database. This issue has been patched in version 2.33.10.

GHSA-w7qc-6grj-w7r8 — File Browser vulnerable to command execution allowlist bypass

Affected: Go: github.com/filebrowser/filebrowser/v2, Go: github.com/filebrowser/filebrowser

## Summary ##

The *Command Execution* feature of Filebrowser only allows the execution of shell command which have been predefined on a user-specific allowlist. The implementation of this allowlist is erroneous, allowing a user to execute additional commands not permitted.

## Impact ##

A user can execute more shell commands than they are authorized for. The concrete impact of this vulnerability depends on the commands configured, and the binaries installed on the server or in the container image. Due to the missing separation of *scopes* on the OS-level, this could give an attacker access to all files managed the application, including the File Browser database.

## Vulnerability Description ##

For a user to make use of the command execution feature, two things need to happen in advance:

1. An administrator needs to grant that account the `Execute commands` permission 2. The command to be executed needs to be listed in the `Commands` input field (also done by an administrator)

If a user tries to execute a different command, it gets rejected by the application.

The allowlist verification of a command happens in the function `CanExecute` in the file `users/users.go`:

```go // CanExecute checks if an user can execute a specific command. func (u *User) CanExecute(command string) bool { if !u.Perm.Execute { return false }

for _, cmd := range u.Commands { if regexp.MustCompile(cmd).MatchString(command) { return true } }

return false } ```

This check employ…
