Hi !

Yep IDS can nowadays detect SQL injection attempts, famous Snort can do this for instance.

What you can also do (what I've done) is to get your web server's logs in real-time and load them into a database. Then 
you can set up as many home-made triggers as you wish on this DB. Quite long but customizable to one's liking !

Pardon the ignorance, but is there any hardware/software based device that can outright prevent/mitigate (detect?) SQL 
injections? Would an IDS be able to prevent this?

tcpdump/ethereal/your favorite packet capturing program.  This will 
definitely yield the 'sa' password (as well as others).

If you're using Windows on your attack platform, consider using Cain & 
Abel as it can do the Man-in-the-Middle/SQL password capture all in one.

Hugo,

Based on the limited info you have provided, here is my advice.

Have you done UDP port scans? If you haven't done so, scan to 
determine what UDP ports are open. Depending on what you find this 
could be helpful. For example, if SNMP is available with a default 
or guessable community name it will provide usernames among other 
goodies.

Re: obtaining the SQL version; since the OS is Win3k the SQL server 
will likely be SQL 2000 with SP3 or later. If you really want to 
find out try SQLVer (www.sqlsecurity.com) as Chip already mentioned 
and try SQLRecon (www.SpecialOpsSecurity.com -click on LABS).

With that said don't give up on the SQL "SA" brute force attacks. 
There is no account lock out for SA so rock and roll. SQLDict.exe 
works pretty well if you have a big dictionary file. Another option 
is ForceSQL.exe because it brute forces an account (sa) based on a 
user specified character set (charset.txt) up to a user specified 
max password length.

You also mentioned DNS: 53. Not sure if you are referring to UDP or 
TCP?
If it is TCP then you should try a zone transfer.

Also don't forget full (1-65535) TCP port scans and source port 
scans
(SRC=20,53,88,80,etc...)

Finally use tracerouting, hping2, tcpdump, etc to determine if the 
blocking ACLs are on the host or a network device. Something is 
facilitating the firewalling that is hiding juicy MS specific ports 
like TCP 135 and 445. Is it ICF, IPSec, a personal firewall, network 
firewall, perimeter router or what? Once you know this it will help 
direct your attempts to subvert that protection and get exposure to 
more ports on the target.

Let us know how it goes!

Good luck,

Hi every one, I'm doing a pen test on a client, and have found that 
he have a windows 2003 server box on one segment of his public 
addresses this is his dns/web/mail server:

- mssql :1433
- terminal services :3389
- iis 6 :80
- smtp :25
- pop3 :110
- dns : 53
- ftp : filtered

ports opened, i logged on the terminal services port whit the winxp 
remote desktop utility and it connects perfectly.

i tried a dictionari atack on mssql server whit the "sa" account and 
others user names i collected.
 Hydra from THC was the tool, but no succes on this atack.
also tried the tsgrinder for terminal services , but no success.


well here come some questions:

- What others Usernames should i try for sql and terminal services?
  i tried whit "sa" for sql and "Administrator" for TS

- Any one knows how could i identify what version of sql server is 
running.
- What other services of this host can be exploited?

any comments, ideas, suggestions would be greatly appreciated.
