Looking at the decoded data at the bottom of the center panel, itвЂ™s easy to identify the query. MSSQL Server 2014 Express did not have encryption enabled by default, so this data was easy to access. Clicking on that packet showed me all of the data contained within. Switching back to Wireshark, I stopped the capture and looked at the captured data. You can see the empty columns listed toward the bottom-right of the screenshot. The query was executed successfully and the empty table was returned to me. This query is designed to pull all information from the database table. There is no actual data in the table, but for this test that is unnecessary. The Products table has two columns named ProductID and ProductName. The database is called testdb and includes one table called Products. With a traffic capture underway, I switched back to the workstation and executed a query against the sample database I built for this test.

(Incidentally, I noticed that the вЂњtds.queryвЂќ filter object is not available on older versions of Wireshark.) This hides all the other traffic and displays just the TDS query packets. I configured Wireshark to use a display filter вЂњtds.queryвЂќ. It started capturing traffic on the primary interface. Once logged in, I launched Wireshark 2.0 on the SQL Server box. If my experiments were successful, I could do a lot of fun things with the SA accountвЂ™s privileges. The SA account is the system admin account in SQL Server and can do anything. In order to make this test more interesting, I used the вЂњSAвЂќ account to log in. The first thing I needed to do was to look at the MSSQL query traffic. This allows the attacker to not only see all of the data between the victims but potentially also to manipulate that traffic. The typical setup is to perform some kind of redirect, like an ARP cache poison (which is still possible in some environments), which forces traffic between two systems to be redirected through the attackerвЂ™s computer. Anitian does these a lot, as we have a lot of expertise on hacking infrastructure devices. This type of attack is known as a man-in-the-middle (MITM) attack. This was nearly identical to the setup I had at the client site. All of these systems are on the same subnet, simulating an attacker on the internal network. My attack machine was a relatively new installation of Kali 2.0 Linux.

The client machine was a Windows 10 system running MSSQL Management Studio 2014. For my investigation, I was running MSSQL Server 2014 Express on Windows Server 2012 R2. What I found was that with a little packet hacking,В I couldВ take control of a Microsoft SQL Server box without having any stolen credentials using a Man in the Middle style attack.Д«ack in my lab, I began to research this more. Was there a way to attack an SQL Server box without any credentials? I decided to take my hypothesis to the lab and try some experiments. However, I could not help thinking I was on to something. So, I had to set my curiosity aside for the time being and complete the penetration test for the client. Unfortunately, for this particular client engagement, cracking SQL Server encryption was beyond the scope of the project. If the installation uses a self-signed certificate, that is fairly easy to crack.

However, MSSQL encrypts login traffic which meant I would have to crack the encryption to get credentials. At first, I thought this might be a way to capture some authentication credentials.

During a recent penetration test, I was hacking away at some packet captures and noticed unencrypted Microsoft SQL Server (MSSQL) traffic.
