How to fix?

Upgrade commons-net:commons-net to version 3.9.0 or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure as the FTP client trusts the host from PASV responses by default. A malicious server can redirect the Commons Net code to use a different host, but the user has to connect to the malicious server in the first place. This may lead to leakage of information about services running on the private network of the client.
