Subject [jira] Commented: (VFS-169) Thrown exception reveals passwords
Date Sun, 03 Aug 2008 18:27:44 GMT


Frank commented on VFS-169:

I think too that the password should never ever be revealed once entered; not in exceptions,
nor in other debug messages.

Probably adapting the AbstractFileName.toString to not print the password would fix most of
this. Then the method getFriendlyURI can be deprecated as well. 

I have one remark though. I really dislike the format 'scheme://user:***@host' where the password
is hidden with *** ; it is ugly and I don't think it serves any purpose to show the ***. 

I would rather prefer 'scheme://user@host' in all cases; it is shorter and more to the point.

I hope you fix this soon ;-)

> If an exception occurs accessing a FileObject on a FileSystem that is addressed with
an URL containing user and password the thrown exception contains the password as part of
the error message:
> org.apache.commons.vfs.FileSystemException: Could not connect to SFTP server at "s".
> In such a case the URL should be printed as "sftp://user:***". Same applied
to log messages - at least for INFO and higher.
> This is a security risk, since in big companies exceptions and logs are normally collected
and archived in monitoring systems and may reveal the password to persons that have normally
no authorization to the target system.
