What database does GoAnywhere Managed File Transfer use, and how can I query it?

GoAnywhere MFT uses the Apache Derby database, located by default in the `userdata/database/goanywhere` folder. You can query it using the Derby ij tool from the command line, for example: `connect 'jdbc:derby:C:\Program Files\HelpSystems\GoAnywhere\userdata\database\goanywhere;';` followed by `SELECT * FROM DPA_USER;`. Alternatively, use a GUI tool like DBSchema with the Derby embedded driver. Refer to the GoAnywhere Managed File Transfer Vulnerability Debugging Environment Setup for more details.
