The only way to do this would be trough a console, or some companies offer the ability to repair permissions [for example server beach has a utility for this]. As soon as you login to console and repair the permissions [for SSH first and only ~ at first], make sure you the first thing you do is block ALL external communications outside of port 80 and SSH [or all communications outside at all ~ if you're in a console session, stay in console and just lock all communications] as your server might have been hacked. Coming from somebody who does security, this is the first thing I would do, lock down SSH so you can't get in and fix anything right away. If you can't get to a console, call the company that hosts it, and ask them if they can repair SSH for you and verify it's integrity (which they should be willing to do at the least) and if they can't, I guess you're screwed unless you get physical access.
