Prevent server path disclosure from Media PostSave endpoint

[shearer3000]

A security penetration test of a client website has reported that the Media upload (PostSave endpoint) can make potentially sensitive information known.

{ "ExceptionMessage": "Access to the path '<our server path removed here>\\umbraco\\Data\\TEMP\\FileUploads' is denied.", "ExceptionType": null, "StackTrace": null }

In this case, this error was raised when trying to upload an Eicar test file https://www.eicar.org/download-anti-malware-testfile/

Can Umbraco not return technical information ("ExceptionMessage") to the browser?

NB This for an environment where Umbraco is configured in production mode:
