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 2.33.10, 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.
