Description Chris Nystrom 2005-10-24 04:36:39 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1

Description of problem:
The default configuration allows direct root login access. The blackhats apparently know this, because I noticed dictionary attacks on my root login from many locations around the world over a period of time. Since there is nothing special about my systems, I assume this is a widespread problem.

I believe better practice would be to have the direct root login disabled. A firewall can mitigate this issue, but I believe it is poor practice to rely only on the firewall for protection. The system should be delivered secure.

I believe that implementing this fix will not cause any undo restriction as legitimate users can easily login via unprivledged accounts and su to root.

Also I note that Solaris is delivered with direct ssh login to root disabled. 

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Install FC4
2. Login via OpenSSH direct to root.
3. Unfortunately it works.

Actual Results:  You have root access to the machine.

Expected Results:  Login should be denied, forcing you to login via a non-privledged account and su to root. Users who need direct login to root can easily re-enable this feature.
