FTP not enabled but port 21 opened on 3000 concentrator?

How can this be?

The VPN 3000 concentrator management software shows that FTP is not enabled, but port 21 is open when I scan the device and try to logon, but fail. I do not have admin rights to it; a network staff member showed me that it was supposed to be not enabled. I monitor an IDS 4250 and reported that the IDS sig 3171 was triggered over 200 times by a European internet IP. I believe that the FTP service is compromised. What is the worst case scenario?

Is the device owned?

Re: FTP not enabled but port 21 opened on 3000 concentrator?

update: the network staff member was looking at the wrong concentrator. the ftp was enabled according to management software. we disabled the ftp protocol and I suggested to change the password. The concentrator is safe now, RIGHT?
