This came to me via an anonymous source but this is a bit of a concern. On more than one query, very sensitive password data was visible.
The original source added that only certain domains had the breach visible.

Confirmed - got sent a few whois queries to try and have seen a whole bunch of user passwords on NetSol - You can Try a Query Here - if your site is registered with NetSol then you may see your passord revealed in the results....
