Yes, there is clearly two issues here - passwords stored on a client through
Enterprise Manager, which is what Pentester is referring to, are stored in
clear text (6.5) or with a bad encryption algorithm (7.0).

The issue you raise is cracking passwords stored in the database tables on
the server. Encryption of these passwords was added after version 4.2. If
you'd like to crack sql server passwords there are several ways out there to
accomplish this. Go to Chip Andrew's website, www.sqlsecurity.com, click on
downloads and then audit.sql. ISS also has a free prototype called SQL
Cracker written by Jon Larimer that cracks 6.x passwords - you can download
it from http://xforce.iss.net/protoworx/index.php.

Now, this was for the passwords stored
in sysxlogins that linked to the users in sysusers- I think this 'stored in
the clear' business was regarding EnterpriseManager as Todd pointed out in
his reply.

Does anyone have any more info on this?  I have penetrated many SQL boxes
and retrieved the master db, but have never been able to crack the passwords
in sysxlogins to get further down range.  I think that if it really were
simple, there would be crackers out there for it.

Additionally, if the 6.5 system users and pwds really are in the clear, why
would Pentester be asking us for the crypto?
